# create-svelte
## Running locally
Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/master/packages/create-svelte).
A local database is only required in dev mode if you want to test reading and writing saved REPLs on it. Without a local database in dev mode, the REPL will be able to load saved REPLs from the production database, but not save them.
## Creating a project
Note also that in dev mode, the REPL will currently only work in Chrome, [as noted in the Vite documentation](https://vitejs.dev/guide/features.html#web-workers), pending support in Firefox for `import` statements in web workers.
If you're seeing this, you've probably already done this step. Congrats!
If you do want to use a database, set it up on [Supabase](https://supabase.com) with the instructions [here](../../db) and set the corresponding environment variables.
```bash
# create a new project in the current directory
npm create svelte@latest
Run the site sub-project:
# create a new project in my-app
npm create svelte@latest my-app
```bash
pnpm install
pnpm dev
```
## Developing
and navigate to [localhost:5173](http://localhost:5173).
Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
The first time you run the site locally, it will update the list of Contributors and REPL dependencies. After this it won't run again unless you force it by running:
```bash
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
pnpm update
```
## Building
## Running using the local copy of Svelte
By default, the REPL will fetch the most recent version of Svelte from https://unpkg.com/svelte. When running the site locally, you can also use your local copy of Svelte.
To create a production version of your app:
To produce the proper browser-compatible UMD build of the compiler, you will need to run `npm run build` (or `npm run dev`) in the `svelte` repository with the `PUBLISH` environment variable set to any non-empty string:
```bash
npm run build
git clone https://github.com/sveltejs/svelte.git
cd svelte
npm ci
PUBLISH=1 npm run build
```
You can preview the production build with `npm run preview`.
The default configuration assumes that the `sites` repository and the `svelte` repository are in the same directory. If not, you can set `LOCAL_SVELTE_PATH` in `sites/svelte.dev/.env` to a different path to the local copy of Svelte.
Then visit the REPL at [localhost:5173/repl?version=local](http://localhost:5173/repl?version=local). Please note that the local REPL only works with `pnpm dev` and not when building the site for production usage.
## REPL GitHub integration
In order for the REPL's GitHub integration to work properly when running locally, you will need to:
- [create a GitHub OAuth app](https://github.com/settings/developers):
- set `Authorization callback URL` to `http://localhost:5173/auth/callback`;
- set `Application name` as you like, and `Homepage URL` as `http://localhost:5173/`;
- create the app and take note of `Client ID` and `Client Secret`
- in this directory, create an `.env.local` file (see `.env.example`) containing:
```
GITHUB_CLIENT_ID=[your app's Client ID]
GITHUB_CLIENT_SECRET=[your app's Client Secret]
```
The GitHub app requires a specific callback URL, and so cannot be used with the preview deployment in the staging environment.
## Building the site
To build the website, run `pnpm build`. The output can be found in `build`.
## Testing
Tests can be run using `pnpm test`.
## Translating the API docs
Anchors are automatically generated using headings in the documentation and by default (for the english language) they are latinised to make sure the URL is always conforming to RFC3986.
> To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.
If we need to translate the API documentation to a language using unicode chars, we can setup this app to export the correct anchors by setting up `SLUG_PRESERVE_UNICODE` to `true` in `config.js`.

export const SLUG_PRESERVE_UNICODE = false;

title: "Frameworks without the framework: why didn't we think of this sooner?"
description: You can't write serious applications in vanilla JavaScript without hitting a complexity wall. But a compiler can do it for you.
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
> Wait, this new framework has a *runtime*? Ugh. Thanks, I'll pass.
> ** front end developers in 2018**
We're shipping too much code to our users. Like a lot of front end developers, I've been in denial about that fact, thinking that it was fine to serve 100kb of JavaScript on page load just use [one less .jpg!](https://twitter.com/miketaylr/status/227056824275333120) and that what *really* mattered was performance once your app was already interactive.
But I was wrong. 100kb of .js isn't equivalent to 100kb of .jpg. It's not just the network time that'll kill your app's startup performance, but the time spent parsing and evaluating your script, during which time the browser becomes completely unresponsive. On mobile, those milliseconds rack up very quickly.
If you're not convinced that this is a problem, follow [Alex Russell](https://twitter.com/slightlylate) on Twitter. Alex [hasn't been making many friends in the framework community lately](https://twitter.com/slightlylate/status/728355959022587905), but he's not wrong. But the proposed alternative to using frameworks like Angular, React and Ember [Polymer](https://www.polymer-project.org/1.0/) hasn't yet gained traction in the front end world, and it's certainly not for a lack of marketing.
Perhaps we need to rethink the whole thing.
## What problem do frameworks *really* solve?
The common view is that frameworks make it easier to manage the complexity of your code: the framework abstracts away all the fussy implementation details with techniques like virtual DOM diffing. But that's not really true. At best, frameworks *move the complexity around*, away from code that you had to write and into code you didn't.
Instead, the reason that ideas like React are so wildly and deservedly successful is that they make it easier to manage the complexity of your *concepts*. Frameworks are primarily a tool for structuring your thoughts, not your code.
Given that, what if the framework *didn't actually run in the browser*? What if, instead, it converted your application into pure vanilla JavaScript, just like Babel converts ES2016+ to ES5? You'd pay no upfront cost of shipping a hefty runtime, and your app would get seriously fast, because there'd be no layers of abstraction between your app and the browser.
## Introducing Svelte
Svelte is a new framework that does exactly that. You write your components using HTML, CSS and JavaScript (plus a few extra bits you can [learn in under 5 minutes](https://v2.svelte.dev/guide)), and during your build process Svelte compiles them into tiny standalone JavaScript modules. By statically analysing the component template, we can make sure that the browser does as little work as possible.
The [Svelte implementation of TodoMVC](https://svelte-todomvc.surge.sh/) weighs 3.6kb zipped. For comparison, React plus ReactDOM *without any app code* weighs about 45kb zipped. It takes about 10x as long for the browser just to evaluate React as it does for Svelte to be up and running with an interactive TodoMVC.
And once your app *is* up and running, according to [js-framework-benchmark](https://github.com/krausest/js-framework-benchmark) **Svelte is fast as heck**. It's faster than React. It's faster than Vue. It's faster than Angular, or Ember, or Ractive, or Preact, or Riot, or Mithril. It's competitive with Inferno, which is probably the fastest UI framework in the world, for now, because [Dominic Gannaway](https://twitter.com/trueadm) is a wizard. (Svelte is slower at removing elements. We're [working on it](https://github.com/sveltejs/svelte/issues/26).)
It's basically as fast as vanilla JS, which makes sense because it *is* vanilla JS  just vanilla JS that you didn't have to write.
## But that's not the important thing
Well, it *is* important performance matters a great deal. What's really exciting about this approach, though, is that we can finally solve some of the thorniest problems in web development.
Consider interoperability. Want to `npm install cool-calendar-widget` and use it in your app? Previously, you could only do that if you were already using (a correct version of) the framework that the widget was designed for if `cool-calendar-widget` was built in React and you're using Angular then, well, hard cheese. But if the widget author used Svelte, apps that use it can be built using whatever technology you like. (On the TODO list: a way to convert Svelte components into web components.)
Or [code splitting](https://twitter.com/samccone/status/797528710085652480). It's a great idea (only load the code the user needs for the initial view, then get the rest later), but there's a problem even if you only initially serve one React component instead of 100, *you still have to serve React itself*. With Svelte, code splitting can be much more effective, because the framework is embedded in the component, and the component is tiny.
Finally, something I've wrestled with a great deal as an open source maintainer: your users always want *their* features prioritised, and underestimate the cost of those features to people who don't need them. A framework author must always balance the long-term health of the project with the desire to meet their users' needs. That's incredibly difficult, because it's hard to anticipate much less articulate the consequences of incremental bloat, and it takes serious soft skills to tell people (who may have been enthusiastically evangelising your tool up to that point) that their feature isn't important enough. But with an approach like Svelte's, many features can be added with absolutely no cost to people who don't use them, because the code that implements those features just doesn't get generated by the compiler if it's unnecessary.
## We're just getting started
Svelte is very new. There's a lot of work still left to do creating build tool integrations, adding a server-side renderer, hot reloading, transitions, more documentation and examples, starter kits, and so on.
But you can already build rich components with it, which is why we've gone straight to a stable 1.0.0 release. [Read the guide](https://v2.svelte.dev/guide), [try it out in the REPL](/repl), and head over to [GitHub](https://github.com/sveltejs/svelte) to help kickstart the next era of front end development.

title: The easiest way to get started with Svelte
description: This'll only take a minute.
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
Svelte is a [new kind of framework](/blog/frameworks-without-the-framework). Rather than putting a `<script src='svelte.js'>` tag on the page, or bringing it into your app with `import` or `require`, Svelte is a compiler that works behind the scenes to turn your component files into beautifully optimised JavaScript.
Because of that, getting started with it can be a little bit confusing at first. How, you might reasonably ask, do you make a Svelte app?
## 1. Use the REPL
The [Svelte REPL](/repl) (Read-Eval-Print Loop) is the easiest way to begin. This is an interactive environment that allows you to modify code and instantly see the result.
You can choose from a list of [examples](/examples/), click the [REPL](/repl) link, and then tweak them until they do what you want.
<aside><p>You'll need to have <a href="https://nodejs.org/">Node.js</a> installed, and know how to use the terminal</p></aside>
At some point, your app will outgrow the REPL. Click the **download** button to save a `svelte-app.zip` file to your computer and uncompress it.
Open a terminal window and set the project up...
```bash
cd /path/to/svelte-app
npm install
```
...then start up a development server:
```bash
npm run dev
```
This will serve your app on [localhost:8080](http://localhost:8080) and rebuild it with [Rollup](https://rollupjs.org) every time you make a change to the files in `svelte-app/src`.
## 2. Use degit
When you download from the REPL, you're getting a customised version of the [sveltejs/template](https://github.com/sveltejs/template) repo. You can skip messing around with zip files by using [degit](https://github.com/Rich-Harris/degit), a project scaffolding tool.
In the terminal, you can instantly create a new project like so:
```bash
npx degit sveltejs/template my-svelte-project
cd my-svelte-project
# to use TypeScript run:
# node scripts/setupTypeScript.js
npm install
npm run dev
```
This will create a new project in the `my-svelte-project` directory, install its dependencies, and start a server on http://localhost:8080.
You can find more information about using TypeScript [here](/blog/svelte-and-typescript).
Once you've tinkered a bit and understood how everything fits together, you can fork [sveltejs/template](https://github.com/sveltejs/template) and start doing this instead:
```bash
npx degit your-name/template my-new-project
```
And that's it! Do `npm run build` to create a production-ready version of your app, and check the project template's [README](https://github.com/sveltejs/template/blob/master/README.md) for instructions on how to easily deploy your app to the web with [Vercel](https://vercel.com) or [Surge](http://surge.sh/).
You're not restricted to using Rollup — there are also integrations for [webpack](https://github.com/sveltejs/svelte-loader), [Browserify](https://github.com/tehshrike/sveltify) and others, or you can use the [Svelte CLI](https://github.com/sveltejs/svelte-cli) (Update from 2019: with Svelte 3 the CLI was deprecated and we now use [sirv-cli](https://www.npmjs.com/package/sirv-cli) in our template. Feel free to use whatever tool you like!) or the [API](https://github.com/sveltejs/svelte/tree/v2#api) directly. If you make a project template using one of these tools, please share it with the [Svelte Discord chatroom](https://svelte.dev/chat), or via [@sveltejs](https://twitter.com/sveltejs) on Twitter!

title: The zen of Just Writing CSS
description: I would say this is the future, but we're already doing it.
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
It's fashionable to dislike CSS. There are lots of reasons why that's the case, but it boils down to this: CSS is *unpredictable*. If you've never had the experience of tweaking a style rule and accidentally breaking some layout that you thought was completely unrelated — usually when you're trying to ship — then you're either new at this or you're a much better programmer than the rest of us.
So the JavaScript community rolled up its sleeves and got to work. Over the last couple of years, there's been a Cambrian explosion of libraries aimed at making CSS behave, collectively referred to as *CSS-in-JS*.
What you might not realise is that **the biggest problems with CSS can be solved without CSS-in-JS**. Without those problems, writing CSS isn't just tolerable — it's enjoyable. And you don't have to find solutions to the additional problems that CSS-in-JS introduces.
This article isn't in any way intended as criticism of the hard work the CSS-in-JS community has done. It's one of the most active corners of the JS ecosystem, and new ideas are springing up every week. Instead, my purpose is to illustrate why an alternative approach — based on Single File Components with real CSS — is so damn delightful.
## The biggest problem with CSS
Everything in CSS is global. Because of that, styles intended for one bit of markup often end up affecting another. Because of *that*, developers often resort to wild namespacing conventions (not 'rules', since they're very difficult to enforce) that mostly just increase your risk of RSI.
It gets worse when you're working on a team. No-one dares touch styles authored by someone else, because it's often unclear what they're doing, what markup they apply to, and what disasters will unfold if you remove them.
The consequence of all this is the **append-only stylesheet**. There's no way of knowing which code can safely be removed, so it's common to undo some existing style with another, more specific style — even on relatively small projects.
## Single File Components change all that
The idea behind SFCs is simple: you write your components in an HTML file that (optionally) contains a `<style>` and `<script>` attribute describing the component's styles and behaviour. Svelte, Ractive, Vue and Polymer all follow this basic pattern.
<aside>
<p><a href="/blog/frameworks-without-the-framework">Read the introductory blog post</a> if you're new to Svelte. Or <a href="https://twitter.com/padolsey/status/899717303234908160">read</a> <a href="https://twitter.com/sveltejs/status/901818357644701696">the</a> <a href="https://twitter.com/sveltejs/status/901818106309476352">testimonials</a>.</p>
</aside>
(For the rest of this article we'll be using Svelte, obviously. But if the idea of using a template language makes you shudder — your fears are misplaced, but that's a topic for another day — then just use Vue which lets you use JSX in your SFCs.)
Several wonderful things happen as a result:
* Your styles are *scoped to the component*. No more leakage, no more unpredictable cascade. And no more sesquipedalian classnames designed to prevent conflicts.
* You don't need to go spelunking through your folder structure to find the rules that are breaking your stuff.
* The compiler (in Svelte's case) can **identify and remove unused styles**. No more append-only stylesheets!
Let's see what that looks like in practice.
<figure>

<source type='video/mp4' src='https://svelte-technology-assets.surge.sh/just-write-css.mp4'>
</video>
<figcaption>
Is this what they mean by 'use the platform'?
</figcaption>
</figure>
Every code editor already knows about CSS, so there's a good chance that you'll get autocomplete, linting, syntax highlighting and so on — all without additional JS-fatigue-inducing tools.
And because it's real CSS, rather than some camelCased quotes-everywhere impostor, we can take advantage of the 'tweak in devtools, paste back into our source code' workflow, which I personally couldn't live without. Notice that we get CSS sourcemaps out of the box, so you can instantly pinpoint the lines in question. It's hard to overstate the importance of this: when you're in WYSIWYG mode, you're not thinking in terms of your component tree, so having a robust way to figure out *where these damn styles came from* is essential. Doubly so if someone else originally wrote the component. (I promise you, this is the single biggest productivity boost to your CSS workflow. If you're writing styles without sourcemaps, you are almost certainly wasting a lot of time. I know I was.)
Svelte transforms your selectors (using an attribute that's also applied to affected elements, though the exact mechanism is unimportant and subject to change) to achieve the scoping. It warns on and removes any unused rules, then it minifies the result and lets you write it out to a `.css` file. There's also an experimental new option to compile to web components, using shadow DOM to encapsulate the styles, if that's your jam.
This is all possible because your CSS is parsed (with [css-tree](https://github.com/csstree/csstree)) and statically analysed in the context of your markup. Static analysis opens the doors to all kinds of exciting future possibilities — smarter optimisations, a11y hints — that are much harder if your styles are computed dynamically at runtime. We're just getting started.
## But we can add tools to do [x]!
If your reaction to the video was 'fine, but if we use TypeScript and write plugins for each editor then we can get all the autocomplete and syntax highlighting stuff' — in other words, if you believe that in order to achieve parity with CSS it makes sense to build, document, promote and maintain a fleet of ancillary projects — then, well, you and I may never see eye to eye!
## We don't have all the answers — yet
Having said all that, CSS-in-JS does point to answers to some lingering questions:
* How can we install styles from npm?
* How can we reuse constants that are defined in a single place?
* How can we compose declarations?
Personally, I haven't found these issues to outweigh the benefits of the approach outlined above. You may well have a different set of priorities, and they may be reason enough for you to abandon CSS.
But at the end of the day, you have to know CSS anyway. Love it or loathe it, you must at least *learn* it. As custodians of the web, we have a choice: create abstractions that steepen the web dev learning curve yet further, or work together to fix the bad parts of CSS. I know which I choose.

title: 'Sapper: Towards the ideal web app framework'
description: Taking the next-plus-one step
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
> Quickstart for the impatient: [the Sapper docs](https://sapper.svelte.dev), and the [starter template](https://github.com/sveltejs/sapper-template)
If you had to list the characteristics of the perfect Node.js web application framework, you'd probably come up with something like this:
1. It should do server-side rendering, for fast initial loads and no caveats around SEO
2. As a corollary, your app's codebase should be universal — write once for server _and_ client
3. The client-side app should _hydrate_ the server-rendered HTML, attaching event listeners (and so on) to existing elements rather than re-rendering them
4. Navigating to subsequent pages should be instantaneous
5. Offline, and other Progressive Web App characteristics, must be supported out of the box
6. Only the JavaScript and CSS required for the first page should load initially. That means the framework should do automatic code-splitting at the route level, and support dynamic `import(...)` for more granular manual control
7. No compromise on performance
8. First-rate developer experience, with hot module reloading and all the trimmings
9. The resulting codebase should be easy to grok and maintain
10. It should be possible to understand and customise every aspect of the system — no webpack configs locked up in the framework, and as little hidden 'plumbing' as possible
11. Learning the entire framework in under an hour should be easy, and not just for experienced developers
[Next.js](https://github.com/zeit/next.js) is close to this ideal. If you haven't encountered it yet, I strongly recommend going through the tutorials at [learnnextjs.com](https://learnnextjs.com). Next introduced a brilliant idea: all the pages of your app are files in a `your-project/pages` directory, and each of those files is just a React component.
Everything else flows from that breakthrough design decision. Finding the code responsible for a given page is easy, because you can just look at the filesystem rather than playing 'guess the component name'. Project structure bikeshedding is a thing of the past. And the combination of SSR (server-side rendering) and code-splitting — something the React Router team [gave up on](https://reacttraining.com/react-router/web/guides/code-splitting), declaring 'Godspeed those who attempt the server-rendered, code-split apps' — is trivial.
But it's not perfect. As churlish as it might be to list the flaws in something _so, so good_, there are some:
- Next uses something called 'route masking' to create nice URLs (e.g. `/blog/hello-world` instead of `/post?slug=hello-world`). This undermines the guarantee about directory structure corresponding to app structure, and forces you to maintain configuration that translates between the two forms
- All your routes are assumed to be universal 'pages'. But it's very common to need routes that only render on the server, such as a 301 redirect or an API endpoint that serves the data for your pages, and Next doesn't have a great solution for this. You can add logic to your `server.js` file to handle these cases, but it feels at odds with the declarative approach taken for pages
- To use the client-side router, links can't be standard `<a>` tags. Instead, you have to use framework-specific `<Link>` components, which is impossible in the markdown content for a blog post such as this one, for example
The real problem, though, is that all that goodness comes for a price. The simplest possible Next app — a single 'hello world' page that renders some static text — involves 66kb of gzipped JavaScript. Unzipped, it's 204kb, which is a non-trivial amount of code for a mobile device to parse at a time when performance is a critical factor determining whether or not your users will stick around. And that's the _baseline_.
We can do better!
## The compiler-as-framework paradigm shift
[Svelte introduced a radical idea](/blog/frameworks-without-the-framework): what if your UI framework wasn't a framework at all, but a compiler that turned your components into standalone JavaScript modules? Instead of using a library like React or Vue, which knows nothing about your app and must therefore be a one-size-fits-all solution, we can ship highly-optimised vanilla JavaScript. Just the code your app needs, and without the memory and performance overhead of solutions based on a virtual DOM.
The JavaScript world is [moving towards this model](https://tomdale.net/2017/09/compilers-are-the-new-frameworks/). [Stencil](https://stenciljs.com), a Svelte-inspired framework from the Ionic team, compiles to web components. [Glimmer](https://glimmerjs.com) _doesn't_ compile to standalone JavaScript (the pros and cons of which deserve a separate blog post), but the team is doing some fascinating research around compiling templates to bytecode. (React is [getting in on the action](https://twitter.com/trueadm/status/944908776896978946), though their current research focuses on optimising your JSX app code, which is arguably more similar to the ahead-of-time optimisations that Angular, Ractive and Vue have been doing for a few years.)
What happens if we use the new model as a starting point?
## Introducing Sapper
<aside><p>The <a href="https://sapper.svelte.dev/docs#Why_the_name">name comes from</a> the term for combat engineers, and is also short for Svelte app maker</p></aside>
[Sapper](https://sapper.svelte.dev) is the answer to that question. **Sapper is a Next.js-style framework that aims to meet the eleven criteria at the top of this article while dramatically reducing the amount of code that gets sent to the browser.** It's implemented as Express-compatible middleware, meaning it's easy to understand and customise.
The same 'hello world' app that took 204kb with React and Next weighs just 7kb with Sapper. That number is likely to fall further in the future as we explore the space of optimisation possibilities, such as not shipping any JavaScript _at all_ for pages that aren't interactive, beyond the tiny Sapper runtime that handles client-side routing.
What about a more 'real world' example? Conveniently, the [RealWorld](https://github.com/gothinkster/realworld) project, which challenges frameworks to develop an implementation of a Medium clone, gives us a way to find out. The [Sapper implementation](https://github.com/sveltejs/realworld) takes 39.6kb (11.8kb zipped) to render an interactive homepage.
<aside><p>Code-splitting isn't free — if the reference implementation used code-splitting, it would be larger still</p></aside>
The entire app costs 132.7kb (39.9kb zipped), which is significantly smaller than the reference React/Redux implementation at 327kb (85.7kb), but even if it was as large it would _feel_ faster because of code-splitting. And that's a crucial point. We're told we need to code-split our apps, but if your app uses a traditional framework like React or Vue then there's a hard lower bound on the size of your initial code-split chunk — the framework itself, which is likely to be a significant portion of your total app size. With the Svelte approach, that's no longer the case.
But size is only part of the story. Svelte apps are also extremely performant and memory-efficient, and the framework includes powerful features that you would sacrifice if you chose a 'minimal' or 'simple' UI library.
## Trade-offs
The biggest drawback for many developers evaluating Sapper would be 'but I like React, and I already know how to use it', which is fair.
If you're in that camp, I'd invite you to at least try alternative frameworks. You might be pleasantly surprised! The [Sapper RealWorld](https://github.com/sveltejs/realworld) implementation totals 1,201 lines of source code, compared to 2,377 for the reference implementation, because you're able to express concepts very concisely using Svelte's template syntax (which [takes all of five minutes to master](https://v2.svelte.dev/guide#template-syntax)). You get [scoped CSS](/blog/the-zen-of-just-writing-css), with unused style removal and minification built-in, and you can use preprocessors like LESS if you want. You no longer need to use Babel. SSR is ridiculously fast, because it's just string concatenation. And we recently introduced [svelte/store](https://v2.svelte.dev/guide#state-management), a tiny global store that synchronises state across your component hierarchy with zero boilerplate. The worst that can happen is that you'll end up feeling vindicated!
But there are trade-offs nonetheless. Some people have a pathological aversion to any form of 'template language', and maybe that applies to you. JSX proponents will clobber you with the 'it's just JavaScript' mantra, and therein lies React's greatest strength, which is that it is infinitely flexible. That flexibility comes with its own set of trade-offs, but we're not here to discuss those.
And then there's _ecosystem_. The universe around React in particular — the devtools, editor integrations, ancillary libraries, tutorials, StackOverflow answers, hell, even job opportunities — is unrivalled. While it's true that citing 'ecosystem' as the main reason to choose a tool is a sign that you're stuck on a local maximum, apt to be marooned by the rising waters of progress, it's still a major point in favour of incumbents.
## Roadmap
We're not at version 1.0.0 yet, and a few things may change before we get there. Once we do (soon!), there are a lot of exciting possibilities.
I believe the next frontier of web performance is 'whole-app optimisation'. Currently, Svelte's compiler operates at the component level, but a compiler that understood the boundaries _between_ those components could generate even more efficient code. The React team's [Prepack research](https://twitter.com/trueadm/status/944908776896978946) is predicated on a similar idea, and the Glimmer team is doing some interesting work in this space. Svelte and Sapper are well positioned to take advantage of these ideas.
Speaking of Glimmer, the idea of compiling components to bytecode is one that we'll probably steal in 2018. A framework like Sapper could conceivably determine which compilation mode to use based on the characteristics of your app. It could even serve JavaScript for the initial route for the fastest possible startup time, then lazily serve a bytecode interpreter for subsequent routes, resulting in the optimal combination of startup size and total app size.
Mostly, though, we want the direction of Sapper to be determined by its users. If you're the kind of developer who enjoys life on the bleeding edge and would like to help shape the future of how we build web apps, please join us on [GitHub](https://github.com/sveltejs/svelte) and [Discord](https://svelte.dev/chat).

title: Svelte v2 is out!
description: Here's what you need to know
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
<aside>Our motto is 'move slowly and break things'. No, wait, that came out wrong...</aside>
Almost a year after we first started talking about version 2 on the Svelte issue tracker, it's finally time to make some breaking changes. This blog post will explain what changed, why it changed, and what you need to do to bring your apps up to date.
## tl;dr
Each of these items is described in more depth below. If you get stuck, ask for help in our friendly [Discord chatroom](https://svelte.dev/chat).
- Install Svelte v2 from npm
- Upgrade your templates with [svelte-upgrade](https://github.com/sveltejs/svelte-upgrade)
- Remove calls to `component.observe`, or add the `observe` method from [svelte-extras](https://github.com/sveltejs/svelte-extras)
- Rewrite calls to `component.get('foo')` as `component.get().foo`
- Return `destroy` from your custom event handlers, rather than `teardown`
- Make sure you're not passing numeric string props to components
## New template syntax
The most visible change: we've made some improvements to the template syntax.
A common piece of feedback we heard was 'ewww, Mustache' or 'ewww, Handlebars'. A lot of people who used string-based templating systems in a previous era of web development *really* dislike them. Because Svelte adopted the `{{curlies}}` from those languages, a lot of people assumed that we somehow shared the limitations of those tools, such as weird scoping rules or an inability to use arbitrary JavaScript expressions.
<aside>If you need to show an actual `{` character, it's as easy as `&amp;#123;`</aside>
Beyond that, JSX proved that double curlies are unnecessary. So we've made our templates more... svelte, by adopting single curlies. The result feels much lighter to look at and is more pleasant to type:
```html
<h1>Hello {name}!</h1>
```
There are a few other updates. But you don't need to make them manually — just run [svelte-upgrade](https://github.com/sveltejs/svelte-upgrade) on your codebase:
```bash
npx svelte-upgrade v2 src
```
This assumes any `.html` files in `src` are Svelte components. You can specify whichever directory you like, or target a different directory — for example, you'd do `npx svelte-upgrade v2 routes` to update a [Sapper](https://sapper.svelte.technology) app.
To see the full set of changes, consult the [svelte-upgrade README](https://github.com/sveltejs/svelte-upgrade#svelte-v2-syntax-changes).
## Computed properties
Another thing that people often found confusing about Svelte is the way computed properties work. To recap, if you had a component with this...
```js
export default {
computed: {
d: (a, b, c) => a = b + c
}
};
```
...then Svelte would first look at the function arguments to see which values `d` depended on, and then it would write code that updated `d` whenever those values changed, by injecting them into the function. That's cool, because it allows you to derive complex values from your component's inputs without worrying about when they need to recomputed, but it's also... *weird*. JavaScript doesn't work that way!
In v2, we use [destructuring](http://www.jstips.co/en/javascript/use-destructuring-in-function-parameters/) instead:
```js
export default {
computed: {
d: ({ a, b, c }) => a = b + c
}
};
```
The Svelte compiler can still see which values `d` depends on, but it's no longer injecting values — it just passes the component state object into each computed property.
Again, you don't need to make this change manually — just run svelte-upgrade on your components, as shown above.
## Sorry, IE11. It's not you, it's... well actually, yeah. It's you
Svelte v1 was careful to only emit ES5 code, so that you wouldn't be forced to faff around with transpilers in order to use it. But it's 2018 now, and almost all browsers support modern JavaScript. By ditching the ES5 constraint, we can generate leaner code.
If you need to support IE11 and friends, you will need to use a transpiler like [Babel](https://babeljs.io/repl) or [Bublé](https://buble.surge.sh/).
## New lifecycle hooks
In addition to `oncreate` and `ondestroy`, Svelte v2 adds two more [lifecycle hooks](https://v2.svelte.dev/guide#lifecycle-hooks) for responding to state changes:
```js
export default {
onstate({ changed, current, previous }) {
// this fires before oncreate, and
// whenever state changes
},
onupdate({ changed, current, previous }) {
// this fires after oncreate, and
// whenever the DOM has been updated
// following a state change
}
};
```
You can also listen to those events programmatically:
```js
component.on('state', ({ changed, current, previous }) => {
// ...
});
```
## component.observe
With the new lifecycle hooks, we no longer need the `component.observe(...)` method:
```js
// before
export default {
oncreate() {
this.observe('foo', foo => {
console.log(`foo is now ${foo}`);
});
}
};
// after
export default {
onstate({ changed, current }) {
if (changed.foo) {
console.log(`foo is now ${current.foo}`);
}
}
};
```
This shrinks the amount of code Svelte needs to generate, and gives you more flexibility. For example, it's now very easy to take action when any one of *several* properties have changed, such as redrawing a canvas without debouncing several observers.
However, if you prefer to use `component.observe(...)`, then you can install it from [svelte-extras](https://github.com/sveltejs/svelte-extras):
```js
import { observe } from 'svelte-extras';
export default {
methods: {
observe
}
};
```
## component.get
This method no longer takes an optional `key` argument — instead, it always returns the entire state object:
```js
// before
const foo = this.get('foo');
const bar = this.get('bar');
// after
const { foo, bar } = this.get();
```
This change might seem annoying initially, but it's the right move: among other things, it's likely to play better with type systems as we explore that space more fully in future.
## event_handler.destroy
If your app has [custom event handlers](https://v2.svelte.dev/guide#custom-event-handlers), they must return an object with a `destroy` method, *not* a `teardown` method (this aligns event handlers with the component API).
## No more type coercion
Previously, numeric values passed to components were treated as numbers:
```html
<Counter start='1'/>
```
That causes unexpected behaviour, and has been changed: if you need to pass a literal number, do so as an expression:
```html
<Counter start={1}/>
```
## Compiler changes
In most cases you'll never need to deal with the compiler directly, so this shouldn't require any action on your part. It's worth noting anyway: the compiler API has changed. Instead of an object with a mish-mash of properties, the compiler now returns `js`, `css`, `ast` and `stats`:
```js
const { js, css, ast, stats } = svelte.compile(source, options);
```
`js` and `css` are both `{ code, map }` objects, where `code` is a string and `map` is a sourcemap. The `ast` is an abstract syntax tree of your component, and the `stats` object contains metadata about the component, and information about the compilation.
Before, there was a `svelte.validate` method which checked your component was valid. That's been removed — if you want to check a component without actually compiling it, just pass the `generate: false` option.
## My app is broken! Help!
Hopefully this covers everything, and the update should be easier for you than it was for us. But if you find bugs, or discover things that aren't mentioned here, swing by [Discord chatroom](https://svelte.dev/chat) or raise an issue on the [tracker](https://github.com/sveltejs/svelte/issues).

title: Using CSS-in-JS with Svelte
description: You don't need to, but you can
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
CSS is a core part of any web app. By extension, a UI framework that doesn't have a built-in way to add styles to your components is unfinished.
That's why Svelte allows you to add CSS in a component's `<style>` tag. Co-locating your CSS with your markup means we can [solve the biggest problems developers face when writing CSS](/blog/the-zen-of-just-writing-css) without introducing new ones, all while providing a rather nice development experience.
But Svelte's style handling does have some limitations. It's too difficult to share styles between components, or apply app-level optimisations. These are areas we plan to address in future versions, but in the meantime if you need those things you can use any framework-agnostic CSS-in-JS library.
## For example
Here, we're using [Emotion](https://emotion.sh) to generate scoped class names that can be used across multiple components:
<div class="max">
<iframe
title="Aphrodite example"
src="/repl/embed?example=blog-svelte-css-in-js"
scrolling="no"
></iframe>
</div>
It's important to note that most CSS-in-JS libraries have a runtime library, and many don't support statically extracting styles out into a separate <code>.css</code> file at build time (which is essential for the best performance). You should therefore only use CSS-in-JS if it's necessary for your application!
Note that you can mix-and-match — you can still use Svelte's built-in CSS handling alongside a CSS-in-JS library.

title: Virtual DOM is pure overhead
description: Let's retire the 'virtual DOM is fast' myth once and for all
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
If you've used JavaScript frameworks in the last few years, you've probably heard the phrase 'the virtual DOM is fast', often said to mean that it's faster than the *real* DOM. It's a surprisingly resilient meme — for example people have asked how Svelte can be fast when it doesn't use a virtual DOM.
It's time to take a closer look.
## What is the virtual DOM?
In many frameworks, you build an app by creating `render()` functions, like this simple [React](https://reactjs.org/) component:
```js
function HelloMessage(props) {
return (
<div className="greeting">
Hello {props.name}
</div>
);
}
```
You can do the same thing without JSX...
```js
function HelloMessage(props) {
return React.createElement(
'div',
{ className: 'greeting' },
'Hello ',
props.name
);
}
```
...but the result is the same — an object representing how the page should now look. That object is the virtual DOM. Every time your app's state updates (for example when the `name` prop changes), you create a new one. The framework's job is to *reconcile* the new one against the old one, to figure out what changes are necessary and apply them to the real DOM.
## How did the meme start?
Misunderstood claims about virtual DOM performance date back to the launch of React. In [Rethinking Best Practices](https://www.youtube.com/watch?v=x7cQ3mrcKaY), a seminal 2013 talk by former React core team member Pete Hunt, we learned the following:
> This is actually extremely fast, primarily because most DOM operations tend to be slow. There's been a lot of performance work on the DOM, but most DOM operations tend to drop frames.
<figure>
<img alt="Pete Hunt at JSConfEU 2013" src="/media/rethinking-best-practices.jpg">
<figcaption>Screenshot from <a href="https://www.youtube.com/watch?v=x7cQ3mrcKaY">Rethinking Best Practices</a> at JSConfEU 2013</figcaption>
</figure>
But hang on a minute! The virtual DOM operations are *in addition to* the eventual operations on the real DOM. The only way it could be faster is if we were comparing it to a less efficient framework (there were plenty to go around back in 2013!), or arguing against a straw man — that the alternative is to do something no-one actually does:
```js
onEveryStateChange(() => {
document.body.innerHTML = renderMyApp();
});
```
Pete clarifies soon after...
> React is not magic. Just like you can drop into assembler with C and beat the C compiler, you can drop into raw DOM operations and DOM API calls and beat React if you wanted to. However, using C or Java or JavaScript is an order of magnitude performance improvement because you don't have to worry...about the specifics of the platform. With React you can build applications without even thinking about performance and the default state is fast.
...but that's not the part that stuck.
## So... is the virtual DOM *slow*?
Not exactly. It's more like 'the virtual DOM is usually fast enough', but with certain caveats.
The original promise of React was that you could re-render your entire app on every single state change without worrying about performance. In practice, I don't think that's turned out to be accurate. If it was, there'd be no need for optimisations like `shouldComponentUpdate` (which is a way of telling React when it can safely skip a component).
Even with `shouldComponentUpdate`, updating your entire app's virtual DOM in one go is a lot of work. A while back, the React team introduced something called React Fiber which allows the update to be broken into smaller chunks. This means (among other things) that updates don't block the main thread for long periods of time, though it doesn't reduce the total amount of work or the time an update takes.
## Where does the overhead come from?
Most obviously, [diffing isn't free](https://twitter.com/pcwalton/status/1015694528857047040). You can't apply changes to the real DOM without first comparing the new virtual DOM with the previous snapshot. To take the earlier `HelloMessage` example, suppose the `name` prop changed from 'world' to 'everybody'.
1. Both snapshots contain a single element. In both cases it's a `<div>`, which means we can keep the same DOM node
2. We enumerate all the attributes on the old `<div>` and the new one to see if any need to be changed, added or removed. In both cases we have a single attribute — a `className` with a value of `"greeting"`
3. Descending into the element, we see that the text has changed, so we'll need to update the real DOM
Of these three steps, only the third has value in this case, since — as is the case in the vast majority of updates — the basic structure of the app is unchanged. It would be much more efficient if we could skip straight to step 3:
```js
if (changed.name) {
text.data = name;
}
```
(This is almost exactly the update code that Svelte generates. Unlike traditional UI frameworks, Svelte is a compiler that knows at *build time* how things could change in your app, rather than waiting to do the work at *run time*.)
## It's not just the diffing though
The diffing algorithms used by React and other virtual DOM frameworks are fast. Arguably, the greater overhead is in the components themselves. You wouldn't write code like this...
```js
function StrawManComponent(props) {
const value = expensivelyCalculateValue(props.foo);
return (
<p>the value is {value}</p>
);
}
```
...because you'd be carelessly recalculating `value` on every update, regardless of whether `props.foo` had changed. But it's extremely common to do unnecessary computation and allocation in ways that seem much more benign:
```js
function MoreRealisticComponent(props) {
const [selected, setSelected] = useState(null);
return (
<div>
<p>Selected {selected ? selected.name : 'nothing'}</p>
<ul>
{props.items.map(item =>
<li>
<button onClick={() => setSelected(item)}>
{item.name}
</button>
</li>
)}
</ul>
</div>
);
}
```
Here, we're generating a new array of virtual `<li>` elements — each with their own inline event handler — on every state change, regardless of whether `props.items` has changed. Unless you're unhealthily obsessed with performance, you're not going to optimise that. There's no point. It's plenty fast enough. But you know what would be even faster? *Not doing that.*
<aside><p><a href="https://reactjs.org/docs/hooks-intro.html">React Hooks</a> doubles down on defaulting to doing unnecessary work, with <a href="https://twitter.com/thekitze/status/1078582382201131008">predictable results</a>.</p></aside>
The danger of defaulting to doing unnecessary work, even if that work is trivial, is that your app will eventually succumb to 'death by a thousand cuts' with no clear bottleneck to aim at once it's time to optimise.
Svelte is explicitly designed to prevent you from ending up in that situation.
## Why do frameworks use the virtual DOM then?
It's important to understand that virtual DOM *isn't a feature*. It's a means to an end, the end being declarative, state-driven UI development. Virtual DOM is valuable because it allows you to build apps without thinking about state transitions, with performance that is *generally good enough*. That means less buggy code, and more time spent on creative tasks instead of tedious ones.
But it turns out that we can achieve a similar programming model without using virtual DOM — and that's where Svelte comes in.

Earlier this month, I had the privilege of appearing on [The Changelog](https://changelog.com/podcast), a podcast about software development. We had a fun (for me) and wide-ranging conversation:
* life as a coder inside a newsroom
* the big compilers-as-frameworks trend
* scalability
* the [Great Divide](https://css-tricks.com/the-great-divide/)
...and, most importantly, Svelte 3.
Unless you hang out in our [Discord server](https://svelte.dev/chat) or follow [@sveltejs](https://twitter.com/sveltejs) on Twitter, you might not know that Svelte 3 is just around the corner, and it's going to be a huge release. We've rethought the developer experience from the ground up, and while it *will* be a nuisance if you need to upgrade a Svelte 2 app (more on that soon) we think you're going to love it.
On the podcast [Adam](https://twitter.com/adamstac), [Jerod](https://twitter.com/jerodsanto) and I talk about some of the changes and why we're making them. You can listen here or on the [podcast page](https://changelog.com/podcast/332).

title: Setting up your editor
description: Instructions for configuring linting and syntax highlighting
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
draft: true
---
*__Coming soon__*
This post will walk you through setting up your editor so that it recognises Svelte files:
* eslint-plugin-svelte3
* svelte-vscode
* associating .svelte files with HTML in VSCode, Sublime, etc.
## Atom
To treat `*.svelte` files as HTML, open *__Edit → Config...__* and add the following lines to your `core` section:
```cson
"*":
core:
customFileTypes:
"text.html.basic": [
"svelte"
]
```
## Vim/Neovim
You can use the [coc-svelte extension](https://github.com/coc-extensions/coc-svelte) which utilises the official language-server.
As an alternative you can treat all `*.svelte` files as HTML. Add the following line to your `init.vim`:
```
au! BufNewFile,BufRead *.svelte set ft=html
```
To temporarily turn on HTML syntax highlighting for the current buffer, use:
```
:set ft=html
```
To set the filetype for a single file, use a [modeline](https://vim.fandom.com/wiki/Modeline_magic):
```
<!-- vim: set ft=html :-->
```
## Visual Studio Code
We recommend using the official [Svelte for VS Code extension](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode).
## JetBrains WebStorm
The [Svelte Framework Integration](https://plugins.jetbrains.com/plugin/12375-svelte/) can be used to add support for Svelte to WebStorm, or other Jetbrains IDEs. Consult the [WebStorm plugin installation guide](https://www.jetbrains.com/help/webstorm/managing-plugins.html) on the JetBrains website for more details.
## Sublime Text 3
Open any `.svelte` file.
Go to *__View → Syntax → Open all with current extension as... → HTML__*.

title: Svelte for new developers
description: Never used Node.js or the command line? No problem
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
This short guide is designed to help you — someone who has looked at the [tutorial](/tutorial) and wants to start creating Svelte apps, but doesn't have a ton of experience using JavaScript build tooling — get up and running.
If there are things that don't make sense, or that we're glossing over, feel free to [raise an issue](https://github.com/sveltejs/svelte/issues) or [suggest edits to this page](https://github.com/sveltejs/svelte/blob/master/site/content/blog/2019-04-16-svelte-for-new-developers.md) that will help us help more people.
If you get stuck at any point following this guide, the best place to ask for help is in the [chatroom](https://svelte.dev/chat).
## First things first
You'll be using the *command line*, also known as the terminal. On Windows, you can access it by running **Command Prompt** from the Start menu; on a Mac, hit `Cmd` and `Space` together to bring up **Spotlight**, then start typing `Terminal.app`. On most Linux systems, `Ctrl-Alt-T` brings up the command line.
The command line is a way to interact with your computer (or another computer! but that's a topic for another time) with more power and control than the GUI (graphical user interface) that most people use day-to-day.
Once on the command line, you can navigate the filesystem using `ls` (`dir` on Windows) to list the contents of your current directory, and `cd` to change the current directory. For example, if you had a `Development` directory of your projects inside your home directory, you would type
```bash
cd Development
```
to go to it. From there, you could create a new project directory with the `mkdir` command:
```bash
mkdir svelte-projects
cd svelte-projects
```
A full introduction to the command line is out of the scope of this guide, but here are a few more useful commands:
* `cd ..` — navigates to the parent of the current directory
* `cat my-file.txt` — on Mac/Linux (`type my-file.txt` on Windows), lists the contents of `my-file.txt`
* `open .` (or `start .` on Windows) — opens the current directory in Finder or File Explorer
## Installing Node.js
[Node](https://nodejs.org/en/) is a way to run JavaScript on the command line. It's used by many tools, including Svelte. If you don't yet have it installed, the easiest way is to download the latest version straight from the [website](https://nodejs.org/en/).
Once installed, you'll have access to three new commands:
* `node my-file.js` — runs the JavaScript in `my-file.js`
* `npm [subcommand]` — [npm](https://www.npmjs.com/) is a way to install 'packages' that your application depends on, such as the [svelte](https://www.npmjs.com/package/svelte) package
* `npx [subcommand]` — a convenient way to run programs available on npm without permanently installing them
## Installing a text editor
To write code, you need a good editor. The most popular choice is [Visual Studio Code](https://code.visualstudio.com/) or VSCode, and justifiably so — it's well-designed and fully-featured, and has a wealth of extensions ([including one for Svelte](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode), which provides syntax highlighting and diagnostic messages when you're writing components).
## Creating a project
We're going to use the [Svelte + Vite](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-svelte) template. You don't have to use a project template, but it means you have to do a lot less setup work.
On the command line, navigate to where you want to create a new project, then type the following lines (you can paste the whole lot, but you'll develop better muscle memory if you get into the habit of writing each line out one at a time then running it):
```bash
npm create vite@latest my-svelte-project -- --template svelte
cd my-svelte-project
npm install
```
> You can replace `--template svelte` with `--template svelte-ts`, if you prefer TypeScript.
This creates a new directory, `my-svelte-project`, adds files from the [create-vite/template-svelte](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-svelte) template, and installs a number of packages from npm. Open the directory in your text editor and take a look around. The app's 'source code' lives in the `src` directory, while the files your app can load are in `public`.
In the `package.json` file, there is a section called `"scripts"`. These scripts define shortcuts for working with your application — `dev`, `build` and `preview`. To launch your app in development mode, type the following:
```bash
npm run dev
```
Running the `dev` script starts a program called [Vite](https://vitejs.dev/). Vite's job is to take your application's source files, pass them to other programs (including Svelte, in our case) and convert them into the code that will actually run when you open the application in a browser.
Speaking of which, open a browser and navigate to http://localhost:5173. This is your application running on a local *web server* (hence 'localhost') on port 5173.
Try changing `src/App.svelte` and saving it. The application will update with your changes.
## Building your app
In the last step, we were running the app in 'development mode'. In dev mode, Svelte adds extra code that helps with debugging, and Vite skips the final step where your app's JavaScript is compressed.
When you share your app with the world, you want to build it in 'production mode', so that it's as small and efficient as possible for end users. To do that, use the `build` command:
```bash
npm run build
```
Your `dist` directory now contains an optimised version of your app. You can run it like so:
```bash
npm run preview
```

title: Write less code
description: The most important metric you're not paying attention to
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
All code is buggy. It stands to reason, therefore, that the more code you have to write the buggier your apps will be.
Writing more code also takes more time, leaving less time for other things like optimisation, nice-to-have features, or being outdoors instead of hunched over a laptop.
In fact it's widely acknowledged that [project development time](https://blog.codinghorror.com/diseconomies-of-scale-and-lines-of-code/) and [bug count](https://www.mayerdan.com/ruby/2012/11/11/bugs-per-line-of-code-ratio) grow *quadratically*, not linearly, with the size of a codebase. That tracks with our intuitions: a ten-line pull request will get a level of scrutiny rarely applied to a 100-line one. And once a given module becomes too big to fit on a single screen, the cognitive effort required to understand it increases significantly. We compensate by refactoring and adding comments — activities that almost always result in *more* code. It's a vicious cycle.
Yet while we obsess — rightly! — over performance numbers, bundle size and anything else we can measure, we rarely pay attention to the amount of code we're writing.
## Readability is important
I'm certainly not claiming that we should use clever tricks to scrunch our code into the most compact form possible at the expense of readability. Nor am I claiming that reducing *lines* of code is necessarily a worthwhile goal, since it encourages turning readable code like this...
```js
for (let i = 0; i <= 100; i += 1) {
if (i % 2 === 0) {
console.log(`${i} is even`);
}
}
```
...into something much harder to parse:
```js
for (let i = 0; i <= 100; i += 1) if (i % 2 === 0) console.log(`${i} is even`);
```
Instead, I'm claiming that we should favour languages and patterns that allow us to naturally write less code.
## Yes, I'm talking about Svelte
Reducing the amount of code you have to write is an explicit goal of Svelte. To illustrate, let's look at a very simple component implemented in React, Vue and Svelte. First, the Svelte version:
<div class="max">
<iframe
title="Simple component example"
src="/repl/embed?example=blog-write-less-code"
scrolling="no"
></iframe>
</div>
How would we build this in React? It would probably look something like this:
```js
import React, { useState } from 'react';
export default () => {
const [a, setA] = useState(1);
const [b, setB] = useState(2);
function handleChangeA(event) {
setA(+event.target.value);
}
function handleChangeB(event) {
setB(+event.target.value);
}
return (
<div>
<input type="number" value={a} onChange={handleChangeA}/>
<input type="number" value={b} onChange={handleChangeB}/>
<p>{a} + {b} = {a + b}</p>
</div>
);
};
```
Here's an equivalent component in Vue:
```html
<template>
<div>
<input type="number" v-model.number="a">
<input type="number" v-model.number="b">
<p>{{a}} + {{b}} = {{a + b}}</p>
</div>
</template>
<script>
export default {
data: function() {
return {
a: 1,
b: 2
};
}
};
</script>
```
<aside>
<p>I'm counting by copying the source code to the clipboard and running `pbpaste | wc -c` in my terminal</p>
</aside>
In other words, it takes 442 characters in React, and 263 characters in Vue, to achieve something that takes 145 characters in Svelte. The React version is literally three times larger!
It's unusual for the difference to be *quite* so obvious — in my experience, a React component is typically around 40% larger than its Svelte equivalent. Let's look at the features of Svelte's design that enable you to express ideas more concisely:
### Top-level elements
In Svelte, a component can have as many top-level elements as you like. In React and Vue, a component must have a single top-level element — in React's case, trying to return two top-level elements from a component function would result in syntactically invalid code. (You can use a fragment — `<>` instead of a `<div>`, but it's the same basic idea, and still results in an extra level of indentation).
In Vue, your markup must be wrapped in a `<template>` element, which I'd argue is redundant.
### Bindings
In React, we have to respond to input events ourselves:
```js
function handleChangeA(event) {
setA(+event.target.value);
}
```
This isn't just boring plumbing that takes up extra space on the screen, it's also extra surface area for bugs. Conceptually, the value of the input is bound to the value of `a` and vice versa, but that relationship isn't cleanly expressed — instead we have two tightly-coupled but physically separate chunks of code (the event handler and the `value={a}` prop). Not only that, but we have to remember to coerce the string value with the `+` operator, otherwise `2 + 2` will equal `22` instead of `4`.
Like Svelte, Vue does have a way of expressing the binding — the `v-model` attribute, though again we have to be careful to use `v-model.number` even though it's a numeric input.
### State
In Svelte, you update local component state with an assignment operator:
```js
let count = 0;
function increment() {
count += 1;
}
```
In React, we use the `useState` hook:
```js
const [count, setCount] = useState(0);
function increment() {
setCount(count + 1);
}
```
This is much *noisier* — it expresses the exact same concept but with over 60% more characters. As you're reading the code, you have to do that much more work to understand the author's intent.
In Vue, meanwhile, we have a default export with a `data` function that returns an object literal with properties corresponding to our local state. Things like helper functions and child components can't simply be imported and used in the template, but must instead be 'registered' by attaching them to the correct part of the default export.
## Death to boilerplate
These are just some of the ways that Svelte helps you build user interfaces with a minimum of fuss. There are plenty of others — for example, [reactive declarations](/tutorial/reactive-declarations) essentially do the work of React's `useMemo`, `useCallback` and `useEffect` without the boilerplate (or indeed the garbage collection overhead of creating inline functions and arrays on each state change).
How? By choosing a different set of constraints. Because [Svelte is a compiler](/blog/frameworks-without-the-framework), we're not bound to the peculiarities of JavaScript: we can *design* a component authoring experience, rather than having to fit it around the semantics of the language. Paradoxically, this results in *more* idiomatic code — for example using variables naturally rather than via proxies or hooks — while delivering significantly more performant apps.

title: "Svelte 3: Rethinking reactivity"
description: It's finally here
author: Rich Harris
authorURL: https://twitter.com/Rich_Harris
---
After several months of being just days away, we are over the moon to announce the stable release of Svelte 3. This is a huge release representing hundreds of hours of work by many people in the Svelte community, including invaluable feedback from beta testers who have helped shape the design every step of the way.
We think you're going to love it.
## What is Svelte?
Svelte is a component framework — like React or Vue — but with an important difference. Traditional frameworks allow you to write *declarative* state-driven code, but there's a penalty: the browser must do extra work to convert those declarative structures into DOM operations, using techniques like [virtual DOM diffing](/blog/virtual-dom-is-pure-overhead) that eat into your frame budget and tax the garbage collector.
Instead, Svelte runs at *build time*, converting your components into highly efficient *imperative* code that surgically updates the DOM. As a result, you're able to write ambitious applications with excellent performance characteristics.
The first version of Svelte was all about [testing a hypothesis](/blog/frameworks-without-the-framework) — that a purpose-built compiler could generate rock-solid code that delivered a great user experience. The second was a small upgrade that tidied things up a bit.
Version 3 is a significant overhaul. Our focus for the last five or six months has been on delivering an outstanding *developer* experience. It's now possible to write components with [significantly less boilerplate](/blog/write-less-code) than you'll find elsewhere. Try the brand new [tutorial](/tutorial) and see what we mean — if you're familiar with other frameworks we think you'll be pleasantly surprised.
To make that possible we first needed to rethink the concept at the heart of modern UI frameworks: reactivity.
<div class="max">
<figure style="max-width: 960px; margin: 0 auto">
<div style="height: 0; padding: 0 0 57.1% 0; position: relative; margin: 0 auto;">
<iframe style="position: absolute; width: 100%; height: 100%; left: 0; top: 0; margin: 0;" src="https://www.youtube-nocookie.com/embed/AdNJ3fydeao" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
</div>
<figcaption>'Rethinking Reactivity' from <a href="https://www.israel.yglfconf.com/">You Gotta Love Frontend Code Camp</a></figcaption>
</figure>
</div>
## Moving reactivity into the language
In old Svelte, you would tell the computer that some state had changed by calling the `this.set` method:
```js
const { count } = this.get();
this.set({
count: count + 1
});
```
That would cause the component to *react*. Speaking of which, `this.set` is almost identical to the `this.setState` method used in classical (pre-hooks) React:
```js
const { count } = this.state;
this.setState({
count: count + 1
});
```
There are some important technical differences (as I explain in the video above, React is not reactive) but conceptually it's the same thing.
<aside>
<p>In fact, Svelte 3 is basically <a href="https://twitter.com/threepointone/status/1057179801109311488">Sunil's fault</a>.</p>
</aside>
That all changed with the advent of [hooks](https://reactjs.org/docs/hooks-intro.html), which handle state in a very different fashion. Many frameworks started experimenting with their own implementations of hooks, but we quickly concluded it wasn't a direction we wanted to go in. Hooks have some intriguing properties, but they also involve some unnatural code and create unnecessary work for the garbage collector. For a framework that's used in [embedded devices](https://mobile.twitter.com/sveltejs/status/1088500539640418304) as well as animation-heavy interactives, that's no good.
So we took a step back and asked ourselves what kind of API would work for us... and realised that the best API is no API at all. We can just *use the language*. Updating some `count` value — and all the things that depend on it — should be as simple as this:
```js
count += 1;
```
Since we're a compiler, we can do that by instrumenting assignments behind the scenes:
```js
count += 1; $$invalidate('count', count);
```
Importantly, we can do all this without the overhead and complexity of using proxies or accessors. It's just a variable.
## New look
Your components aren't the only thing that's getting a facelift. Svelte itself has a completely new look and feel, thanks to the amazing design work of [Achim Vedam](https://vedam.de/) who created our new logo and website, which has moved from [svelte.technology](https://svelte.technology) to [svelte.dev](https://svelte.dev).
We've also changed our tagline, from 'The magical disappearing UI framework' to 'Cybernetically enhanced web apps'. Svelte has many aspects — outstanding performance, small bundles, accessibility, built-in style encapsulation, declarative transitions, ease of use, the fact that it's a compiler, etc — that focusing on any one of them feels like an injustice to the others. 'Cybernetically enhanced' is designed to instead evoke Svelte's overarching philosophy that our tools should work as intelligent extensions of ourselves — hopefully with a retro, William Gibson-esque twist.
## Upgrading from version 2
If you're an existing Svelte 2 user, I'm afraid there is going to be some manual upgrading involved. In the coming days we'll release a migration guide and an updated version of [svelte-upgrade](https://github.com/sveltejs/svelte-upgrade) which will do the best it can to automate the process, but this *is* a significant change and not everything can be handled automatically.
We don't take this lightly: hopefully once you've experienced Svelte 3 you'll understand why we felt it was necessary to break with the past.
## Still to come
As grueling as this release has been, we're nowhere near finished. We have a ton of ideas for generating smarter, more compact code, and a long feature wish-list. [Sapper](https://sapper.svelte.dev), our Next.js-style app framework, is still in the middle of being updated to use Svelte 3. The [Svelte Native](https://svelte-native.technology/) community project, which allows you to write Android and iOS apps in Svelte, is making solid progress but deserves more complete support from core. We don't yet have the bounty of editor extensions, syntax highlighters, component kits, devtools and so on that other frameworks have, and we should fix that. We *really* want to add first-class TypeScript support.
But in the meantime we think Svelte 3 is the best way to build web apps yet. Take an hour to go through the [tutorial](/tutorial) and we hope to convince you of the same. Either way, we'd love to see you in our [Discord chatroom](https://svelte.dev/chat) and on [GitHub](https://github.com/sveltejs/svelte) — everyone is welcome, especially you.

title: Svelte <3 TypeScript
description: Typernetically enhanced web apps
author: Orta Therox
authorURL: https://twitter.com/orta
---
It's been by far the most requested feature for a while, and it's finally here: Svelte officially supports TypeScript.
We think it'll give you a much nicer development experience — one that also scales beautifully to larger Svelte code bases — regardless of whether you use TypeScript or JavaScript.

</figure>
## Try it now
You can start a new Svelte TypeScript project using the [normal template](https://github.com/sveltejs/template) and by running `node scripts/setupTypeScript.js` before you do anything else:
```bash
npx degit sveltejs/template svelte-typescript-app
cd svelte-typescript-app
node scripts/setupTypeScript.js
```
If you're a VS Code user, make sure you're using the (new) [official extension](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode), which replaces the popular extension by James Birtles.
Later in this blog post, we'll detail the individual steps involved in using TypeScript in an existing Svelte project.
## What does it mean to support TypeScript in Svelte?
TypeScript support in Svelte has been possible for a long time, but you had to mix a lot of disparate tools together and each project ran independently. Today, nearly all of these tools live under the Svelte organization and are maintained by a set of people who take responsibility over the whole pipeline and have common goals.
A week before COVID was declared a pandemic, [I pitched a consolidation](https://github.com/sveltejs/svelte/issues/4518) of the best Svelte tools and ideas from similar dev-ecosystems and provided a set of steps to get first class TypeScript support. Since then, many people have pitched in and written the code to get us there.
When we say that Svelte now supports TypeScript, we mean a few different things:
* You can use TypeScript inside your `<script>` blocks — just add the `lang="ts"` attribute
* Components with TypeScript can be type-checked with the `svelte-check` command
* You get autocompletion hints and type-checking as you're writing components, even in expressions inside markup
* TypeScript files understand the Svelte component API — no more red squiggles when you import a `.svelte` file into a `.ts` module
### How does it work?
To understand the two main parts of TypeScript support, we'll compare it to the technique TypeScript uses to provide dev tools. There is a compiler `tsc` which you run on the command-line to convert `*.ts` to `*.js`, then there is a `TSServer` which is a node API that responds to requests from text editors. The `TSServer` is what provides all the JavaScript and TypeScript realtime introspection for editors while coding, and it has most of the compiler's code inside it.
For Svelte, we have the Svelte compiler, and now we have the [`svelte-language-server`](https://github.com/sveltejs/language-tools/tree/master/packages/language-server#svelte-language-server) which responds to text editor calls via the [Language Server Protocol standard](https://microsoft.github.io//language-server-protocol/overviews/lsp/overview/). First class TypeScript support means that _both_ of these two systems do a good job of handling TypeScript code.
The Svelte compiler support for TypeScript is handled by [Christian Kaisermann](https://github.com/kaisermann)'s [`svelte-preprocess`](https://github.com/sveltejs/svelte-preprocess#svelte-preprocess) which is now an official Svelte project.
For the editor level, we took inspiration from [Pine's](https://github.com/octref) work in the [Vue](https://vuejs.org) ecosystem via [Vetur](https://github.com/vuejs/vetur). Vetur provides an [LSP](https://github.com/vuejs/vetur/blob/master/server), a VS Code extension and a [CLI](https://github.com/vuejs/vetur/blob/master/vti). Svelte now also has an [LSP](https://github.com/sveltejs/language-tools/blob/master/packages/language-server), a [VS Code extension](https://github.com/sveltejs/language-tools/blob/master/packages/svelte-vscode) and a [CLI](https://github.com/sveltejs/language-tools/blob/master/packages/svelte-check).
### `*.svelte` Introspection
For the official Svelte VS Code extension, we built off the foundations which [James Birtles](https://github.com/UnwrittenFun) has created in [`UnwrittenFun/svelte-vscode`](https://github.com/UnwrittenFun/svelte-vscode) and [`UnwrittenFun/svelte-language-server`](https://github.com/UnwrittenFun/svelte-language-server/).
[Simon Holthausen](https://github.com/dummdidumm) and [Lyu, Wei-Da](https://github.com/jasonlyu123) have done great work improving the JavaScript and TypeScript introspection, including integrating [@halfnelson](https://github.com/halfnelson)'s [svelte2tsx](https://github.com/sveltejs/language-tools/tree/master/packages/svelte2tsx#svelte2tsx) which powers understanding the props on components in your codebase.
## Adding TypeScript to an existing project
Before getting started, add the dependencies:
```bash
npm install --save-dev @tsconfig/svelte typescript svelte-preprocess svelte-check
```
### 1. Compiling TypeScript
You first need to set up [`svelte-preprocess`](https://github.com/sveltejs/svelte-preprocess#svelte-preprocess), which passes the contents of your `<script lang="ts">` blocks through the TypeScript compiler.
In a Rollup project, that would look like this — note that we also need to install `@rollup/plugin-typescript` so that Rollup can handle `.ts` files:
```diff
+ import autoPreprocess from 'svelte-preprocess';
+ import typescript from '@rollup/plugin-typescript';
export default {
...,
plugins: [
svelte({
+ preprocess: autoPreprocess()
}),
+ typescript({ sourceMap: !production })
]
}
```
[Full instructions for other environments here](https://github.com/sveltejs/svelte-preprocess#usage).
To configure TypeScript, you will need to create a `tsconfig.json` in the root of your project:
```json
{
"extends": "@tsconfig/svelte/tsconfig.json",
"include": ["src/**/*", "src/node_modules"],
"exclude": ["node_modules/*", "__sapper__/*", "public/*"],
}
```
Your `include`/`exclude` may differ per project — these are defaults that should work across most Svelte projects.
### 2. Editor Support
Any editor [using an LSP](https://langserver.org/#implementations-client) can be supported. The [VS Code](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode) extension has been our primary focus, but there is work in progress [on Atom](https://github.com/sveltejs/language-tools/pull/160), and Vim via [coc-svelte](https://github.com/coc-extensions/coc-svelte) has been updated with the latest LSP.
These editor extensions will improve your coding experience even if you only use JavaScript. The editor won't offer errors, but it will offer inference and refactoring tools. You can [add `// @ts-check`](https://www.staging-typescript.org/docs/handbook/intro-to-js-ts.html) to the top of a `<script>` tag using JavaScript to get better error messages with no infra changes.
To switch a `<script>` to use TypeScript, use `<script lang="ts">` and that should be it. Hopefully you won't be seeing an ocean of red squiggles.
### 3. CI Checks
Having red squiggles is great, well, kinda. On the long run though, you want to be able to verify that there are no errors in your code. To verify your project is error free, you can use the CLI tool [`svelte-check`](https://www.npmjs.com/package/svelte-check). It acts like an editor asking for errors against all of your `.svelte` files.
You can add the dependency to your project and then add it to CI.
```bash
npx svelte-check
Loading svelte-check in workspace: /Users/ortatherox/dev/svelte/example-app
Getting Svelte diagnostics...
====================================
/Users/ortatherox/dev/svelte/example-app/src/App.svelte:3:2
Error: Type '123' is not assignable to type 'string'. (ts)
====================================
svelte-check found 1 error
error Command failed with exit code 1.
```
## What about TypeScript in Sapper projects?
TypeScript support was added to Sapper in 0.28, so if you're using an older version be sure to [upgrade](https://sapper.svelte.dev/migrating#0_27_to_0_28).
## How can I contribute?
We're so glad you asked. The work is happening in the [sveltejs/language-tools](https://github.com/sveltejs/language-tools) repo and in the [#language-tools](https://discord.gg/enV6v8K) channel in the Svelte Discord. If you'd like to report issues, submit fixes, or help out with extensions for new editors and so on, that's where you can find us. See you there!

title: "What's new in Svelte: October 2020"
description: New object methods, in-depth learning resources and tons of integration examples!
author: Dani Sandoval
authorURL: https://dreamindani.com
---
Welcome to the first edition of our "What's new in Svelte" series! We'll try to make this a monthly blog post in which you'll find out about new features, bug fixes, and a showcase of Svelte projects from around the community.
## New features
1. `use:obj.method` allows functions defined within objects to be used within actions ([Example](https://svelte.dev/repl/c305722adb4a4545b27b198ea8ff9bde?version=3.27.0), **3.26.0**, warning removed in **3.27.0**)
2. `_` is now supported as a "numerical separator", similar to a `.` or `,` ([Example](https://svelte.dev/repl/844c39e91d1248649fe54af839fab570?version=3.26.0), **3.26.0**)
3. `import.meta` now works in template expressions ([Example](https://svelte.dev/repl/9630de41957a4c80a4fce264360a6bc7?version=3.26.0), **3.26.0**)
4. CSS Selectors with `~` and `+` combinators are now supported ([Example](https://svelte.dev/repl/91ad9257d2d1430185a504a18cc60172?version=3.29.0), **3.27.0**, with a compiler fix in **3.29.0**)
5. The `{#key}` block is now available to key arbitrary content on an expression. Whenever the expression changes, the contents inside the `{#key}` block will be destroyed and recreated. For an in-depth explanation and to find out how it's implemented, check out the [new blog post](https://lihautan.com/contributing-to-svelte-implement-key-block/) of Svelte Team member Tan Li Hau. ([More info](https://github.com/sveltejs/svelte/issues/1469), **3.29.0**)
6. Slots can now be forwarded through child components! This used to only be possible by adding extra wrapper `<div>`s ([More info](https://github.com/sveltejs/svelte/issues/2079), **3.29.0**)
7. When using TypeScript, you can now type the `createEventDispatcher` method:
```html
<script lang="ts">
import { createEventDispatcher } from 'svelte';
const dispatch = createEventDispatcher<{
/**
* you can also add docs
*/
checked: boolean; // Will translate to `CustomEvent<boolean>`
hello: string;
}>();
// ...
</script>
```
This will make sure that you can invoke dispatch only with the specified event names and its types. The Svelte for VS Code extension was also updated to deal with this new feature. It will provide strong typings for these events as well as autocompletion and hover information.
**New from Sapper!**
Sapper 0.28.9 just came out. The highlights from it include much better support for CSP nonces, asset preload support for exported pages, and error details are now available in the `$page` store on error pages.
In addition, Sapper's CSS handling has been rewritten over the course of recent releases in order to fix existing CSS handling bugs, refactor the CSS handling to occur entirely within a Rollup plugin, and remove the need internally to register CSS in the routing system. Congrats and thank you to the folks working on Sapper for all their solid work!
## Impactful bug fixes
- CSS compilation will no longer remove rules for the `open` attribute on `<details>` elements ([Example](https://svelte.dev/repl/ab4c0c177d1f4fab92f46eb8539cea9a?version=3.26.0), **3.26.0**)
- `prettier-plugin-svelte` will do a better job now at dealing with whitespaces, especially around inline elements. It will also preserve formatting inside `<pre>` tags and will no longer format languages which are not supported by Prettier, like SASS, Pug or Stylus.

title: "What's new in Svelte: November 2020"
description: Slot forwarding fixes, SvelteKit for faster local development, and more from Svelte Summit
author: Dani Sandoval
authorURL: https://dreamindani.com
---
Welcome back to the "What's new in Svelte" series! This month, we're covering new features & bug fixes, last month's Svelte Summit and some stand-out sites and libraries...
## New features & impactful bug fixes
1. Destructuring Promises now works as expected by using the `{#await}` syntax
(**3.29.3**, [Example](https://svelte.dev/repl/3fd4e2cecfa14d629961478f1dac2445?version=3.29.3))
2. Slot forwarding (released in 3.29.0) should no longer hang during compilation (**3.29.3**, [Example](https://svelte.dev/repl/29959e70103f4868a6525c0734934936?version=3.29.3))
3. Better typings for the `get` function in `svelte/store` and on lifecycle hooks (**3.29.1**)
**What's going on in Sapper?**
Sapper got some new types in its `preload` function, which will make typing easier if you are using TypeScript. See the [Sapper docs](https://sapper.svelte.dev/docs#Typing_the_function) on how to use them. There also were fixes to `preload` links in exported sites. Route layouts got a few fixes too - including ensuring CSS is applied to nested route layouts. You can also better organize your files now that extensions with multiple dots are supported. (**0.28.10**)
For all the features and bugfixes see the CHANGELOGs for [Svelte](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md) and [Sapper](https://github.com/sveltejs/sapper/blob/master/CHANGELOG.md).
## [Svelte Summit](https://sveltesummit.com/) was Svelte-tacular!
- Rich Harris demoed the possible future of Svelte development in a talk titled "Futuristic Web Development". The not-yet-public project is called SvelteKit (name may change) and will bring a first-class developer experience and more flexibility for build outputs.

title: What's the deal with SvelteKit?

If you attended [Svelte Summit](https://sveltesummit.com/) last month you may have seen my talk, Futuristic Web Development, in which I finally tackled one of the most frequently asked questions about Svelte: when will Sapper reach version 1.0?
The answer: never.
This was slightly tongue-in-cheek — as the talk explains, it's really more of a rewrite of Sapper coupled with a rebrand — but it raised a lot of new questions from the community, and it's time we offered a bit more clarity on what you can expect from Sapper's successor, SvelteKit.

## What's Sapper?
[Sapper](https://sapper.svelte.dev) is an *app framework* (or 'metaframework') built on top of Svelte (which is a *component* framework). Its job is to make it easy to build Svelte apps with all the modern best practices like server-side rendering (SSR) and code-splitting, and to provide a project structure that makes development productive and fun. It uses *filesystem-based routing* (as popularised by [Next](https://nextjs.org/) and adopted by many other frameworks, albeit with some enhancements) — your project's file structure mirrors the structure of the app itself.
While the Svelte homepage and documentation encourages you to [degit](https://github.com/Rich-Harris/degit) the [sveltejs/template](https://github.com/sveltejs/template) repo to start building an app, Sapper has long been our recommended way to build apps; this very blog post is (at the time of writing!) rendered with Sapper.
## Why are we migrating to something new?
Firstly, the distinction between [sveltejs/template](https://github.com/sveltejs/template) and [sveltejs/sapper-template](https://github.com/sveltejs/sapper-template) is confusing, particularly to newcomers to Svelte. Having a single recommended way to start building apps with Svelte will bring enormous benefits: we simplify onboarding, reduce the maintenance and support burden, and can potentially begin to explore the new possibilities that are unlocked by having a predictable project structure. (This last part is deliberately vague because it will take time to fully understand what those possibilities are.)
Aside from all that, we've been tempted by the thought of rewriting Sapper for a while. This is partly because the codebase has become a little unkempt over the years ([Sapper started in 2017](/blog/sapper-towards-the-ideal-web-app-framework)), but mostly because the web has changed a lot recently, and it's time to rethink some of our foundational assumptions.
## How is this new thing different?
The first of those foundational assumptions is that you need to use a module bundler like [webpack](https://webpack.js.org/) or [Rollup](https://rollupjs.org/) to build apps. These tools trace the dependency graph of your application, analysing and transforming code along the way (turning Svelte components to JS modules, for example), in order to create bundles of code that can run anywhere. As the original creator of Rollup, I can attest that it is a surprisingly complex problem with fiendish edge cases.
You certainly needed a bundler several years ago, because browsers didn't natively support the `import` keyword, but it's much less true today. Right now, we're seeing the rise of the *unbundled development* workflow, which is radically simpler: instead of eagerly bundling your app, a dev server can serve modules (converted to JavaScript, if necessary) *on-demand*, meaning startup is essentially instantaneous however large your app becomes.
[Snowpack](https://www.snowpack.dev/) is at the vanguard of this movement, and it's what powers SvelteKit. It's astonishingly fast, and has a beautiful development experience (hot module reloading, error overlays and so on), and we've been working closely with the Snowpack team on features like SSR. The hot module reloading is particularly revelatory if you're used to using Sapper with Rollup (which has never had first-class HMR support owing to its architecture, which prioritises the most efficient output).
That's not to say we're abandoning bundlers altogether. It's still essential to optimise your app for production, and SvelteKit uses Rollup to make your apps as fast and lean as they possibly can be (which includes things like extracting styles into static `.css` files).
The other foundational assumption is that a server-rendered app needs, well, a server. Sapper effectively has two modes — `sapper build`, which creates a standalone app that has to run on a Node server, and `sapper export` which bakes your app out as a collection of static files suitable for hosting on services like GitHub Pages.
Static files can go pretty much anywhere, but running a Node server (and monitoring/scaling it etc) is less straightforward. Nowadays we're witnessing a shift towards *serverless platforms*, in which you as the app author don't need to think about the server your code is running on, with all the attendant complexity. You can get Sapper apps running on serverless platforms, thanks to things like [vercel-sapper](https://github.com/thgh/vercel-sapper), but it's certainly not what you'd call idiomatic.
<aside><p>It'll still be possible to create both Node apps and fully pre-rendered (aka exported) sites</a></p></aside>
SvelteKit fully embraces the serverless paradigm, and will launch with support for all the major serverless providers, with an 'adapter' API for targeting any platforms that we don't officially cater to. In addition, we'll be able to do partial pre-rendering, which means that static pages can be generated at build time but dynamic ones get rendered on-demand.
## When can I start using it?
If you're feeling brave, you can start right now:
```bash
npm init svelte@next
```
This will scaffold a new project and install the `@sveltejs/kit` CLI, which provides the tools for developing and building an app.
We don't recommend it though! There are no docs, and we won't be able to offer any form of support. It's also likely to break often.
The work is being done in a private monorepo while we're still in exploration mode. Our plan is to get a public beta ready and announce it here once we've closed a few issues — the repo itself will remain private at that time, but we'll create a place to collect feedback from the YOLO crowd. After that, we'll work towards a 1.0 release which will involve opening the repo up.
I'm not going to make any firm promises about timings, because I don't like to break promises. But I *think* we're talking about weeks rather than months.
## What if I don't want to use SvelteKit?
You won't have to — it will always be possible to use Svelte as a standalone package or via a bundler integration like [rollup-plugin-svelte](https://github.com/sveltejs/rollup-plugin-svelte). We think it's essential that you can bend Svelte to fit your workflow, however esoteric, and use third-party app frameworks like [Elder.js](https://github.com/Elderjs/elderjs), [Routify](https://routify.dev/), [Plenti](https://plenti.co/), [Crown](https://crownframework.com/), [JungleJS](https://www.junglejs.org/) and others.
## TypeScript?
Don't worry, we won't launch without full TypeScript support.
## How can I migrate my existing Sapper apps?
For the most part, it should be relatively straightforward to migrate a Sapper codebase.
There are some unavoidable changes (being able to run on serverless platforms means we need to replace custom `server.js` files and `(req, res) => {...}` functions with more portable equivalents), and we're taking the opportunity to fix a few design flaws, but on the whole a SvelteKit app will feel very familiar to Sapper users.
Detailed migration guides will accompany the 1.0 launch.
## How can I contribute?
Keep your eyes peeled for announcements about when we'll launch the public beta and open up the repo. (Also, blog post TODO but I would be remiss if I didn't mention that we now have an [OpenCollective](https://opencollective.com/svelte) where you can contribute financially to the project if it's been valuable to you. Many, many thanks to those of you who already have.)
## Where can I learn more?
Follow [@sveltejs](https://twitter.com/sveltejs) and [@SvelteSociety](https://twitter.com/SvelteSociety) on Twitter, and visit [svelte.dev/chat](https://svelte.dev/chat). You should also subscribe to [Svelte Radio](https://www.svelteradio.com/), where Kevin and his co-hosts will grill me about this project on an upcoming episode (and between now and next week when we record it, [reply to this Twitter thread](https://twitter.com/Rich_Harris/status/1323376048571121665) with your additional questions).

title: "What's new in Svelte: December 2020"
description: Better tooling, export maps and improvements to slots and context
author: Dani Sandoval
authorURL: https://dreamindani.com
---
It's the last "What's new in Svelte" of the year and there's lots to celebrate! This month's coverage includes updates from `rollup-plugin-svelte`, `Sapper` and `SvelteKit` and a bunch of showcases from the Svelte community!
## New features & impactful bug fixes
1. `$$props`, `$$restProps`, and `$$slots` are all now supported in custom web components (**3.29.5**, [Example](https://svelte.dev/repl/ad8e6f39cd20403dacd1be84d71e498d?version=3.29.5)) and `slot` components now support spread props: `<slot {...foo} />` (**3.30.0**)
2. A new `hasContext` lifecycle function makes it easy to check whether a `key` has been set in the context of a parent component (**3.30.0** & **3.30.1**, [Docs](https://svelte.dev/docs#run-time-svelte-hascontext))
3. There is now a new `SvelteComponentTyped` class which makes it easier to add strongly typed components that extend base Svelte components. Component library and framework authors rejoice! An example: `export class YourComponent extends SvelteComponentTyped<{aProp: boolean}, {click: MouseEvent}, {default: {aSlot: string}}> {}` (**3.31.0**, [RFC](https://github.com/sveltejs/rfcs/pull/37))
4. Transitions within `{:else}` blocks should now complete successfully (**3.29.5**, [Example](https://svelte.dev/repl/49cef205e5da459594ef2eafcbd41593?version=3.29.5))
5. Svelte now includes an export map, which explicitly states which files can be imported from its npm package (**3.29.5** with some fixes in **3.29.6**, **3.29.7** and **3.30.0**)
6. `rollup-plugin-svelte` had a new [7.0.0 release](https://github.com/sveltejs/rollup-plugin-svelte/blob/master/CHANGELOG.md). The biggest change is that the `css` option was removed. Users who were using that option should add another plugin like `rollup-plugin-css-only` as demonstrated [in the template](https://github.com/sveltejs/template/blob/5b1135c286f7a649daa99825a077586655051649/rollup.config.js#L48)
## What's going on in Sapper?
Lots of new TypeScript definition improvements to make editing Sapper apps even easier! CSS for dynamic imports also should now work in `client.js` files. (Unreleased)
## What's the deal with SvelteKit?
We're glad you asked! If you didn't catch Rich's blog post from early last month, [you can find it here](https://svelte.dev/blog/whats-the-deal-with-sveltekit)!
For all the features and bugfixes see the CHANGELOGs for [Svelte](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md) and [Sapper](https://github.com/sveltejs/sapper/blob/master/CHANGELOG.md).

title: "What's new in Svelte: January 2021"
description: A Svelte-packed showcase to kick-off the new year!
author: Dani Sandoval
authorURL: https://dreamindani.com
---
Happy new year from Svelte! In the last month we made progress on Sapper's upcoming release, fine-tuned our `SvelteComponent` typings, and have seen some amazing apps, sites, and libraries coming out in the showcase.
## What's changed in Svelte?
A new minor release replaces the `SvelteComponent` class with a `SvelteComponentTyped` class. This renaming should help with backwards compatibility. We've updated [last month's blog post](https://svelte.dev/blog/whats-new-in-svelte-december-2020) to avoid any confusion with the name change.
If you're using `SvelteComponent` or the new `SvelteComponentTyped` in your project or library, let us know what you're using it for and we'll add it to the showcase!
## What's going on in Sapper?
More quality of life features are landing in the upcoming release every day. `0.29.0` will include new TypeScript definitions, fixes to scroll tracking and prefetching behavior, and improvements to the runtime router to support encoded query parameters.
If you're upgrading from 0.28.x, check out [the migration guide](https://sapper.svelte.dev/migrating/#0_28_to_0_29) for steps on updating to Sapper 0.29.
## Is SvelteKit ready yet?
To avoid too much churn during development, SvelteKit is still being worked on in a private repo. There will be an announcement on the Discord, blog and Twitter when it's ready for a larger group of users and contributors.
In the meantime, you can explore the current build by running `npm init svelte@next` from your command line.
As cautioned in _[What's the deal with SvelteKit?](https://svelte.dev/blog/whats-the-deal-with-sveltekit)_, there are no docs or support available yet... So use at your own risk / for your own enjoyment!

title: "What's new in Svelte: February 2021"
description: Integrations and improvements at lightning speed...
author: Dani Sandoval
authorURL: https://dreamindani.com
---
With the shortest month of the year coming up, Svelte maintainers and community members alike have been busy this last month from big changes in `svelte-loader`, `prettier-plugin-svelte`, `rollup-plugin-svelte`, and `language-tools` to steady progress in Sapper and `svelte-preprocess`. Meanwhile, lots of folks have been busy integrating Svelte with other popular frameworks.
## New compiler features
- Aria roles from the [WAI-ARIA Graphics Module](https://www.w3.org/TR/graphics-aria-1.0/#role_definitions) are now recognized as valid aria roles in Svelte components (**3.31.1**)
- Compiler warnings for the common React attributes, `className` and `htmlFor`, now make it easier to port React components to Svelte (**3.31.1**)
Have a suggestion for a compiler feature or want to help implement new features/bug fixes? Check out the ["triage: good first issue" tag for Svelte](https://github.com/sveltejs/svelte/issues?q=is%3Aopen+is%3Aissue+label%3A%22triage%3A+good+first+issue%22)
## New bits in language-tools
- User disabled auto import suggestions no longer show in VS Code (**103.0.0**)
- Renaming a variable is now safer with smart additions of a prefix/suffix to renamed variables (**104.0.0**)
- Semantic (token) highlighting for TypeScript users lets theme makers apply semantic styling in their themes, if they support it (**104.0.0**)
- "Extract Component" has been added to the context menu - allowing you to extract components out of files without having to open the command window to type "Svelte: Extract Component" (**104.0.0**)
- The VS Code extension now listens to JavaScript/TypeScript file changes - you no longer need to save the files for the changes to be noticed (**104.1.0**)
For the complete list of changes, check out the language-tools [Releases page](https://github.com/sveltejs/language-tools/releases).
A great way to try the language tools is to download the [Svelte Extension for VSCode](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode). This extension provides syntax highlighting and rich intellisense for Svelte components in VS Code, using the svelte language server. Check your editor's extension sources to see if there's a Svelte plugin for your IDE or build your own (see [coc-svelte](https://github.com/coc-extensions/coc-svelte) for example)!
## Big improvements across the Svelte ecosystem
- [svelte-loader](https://github.com/sveltejs/svelte-loader) released a major version, 3.0.0 - featuring Webpack 5 and Node 14 support, better hot reloading, and new `compilerOptions` to match `rollup-plugin-svelte`. Breaking changes include dropping Svelte 2 and Node 8 support. [More info in the changelog](https://github.com/sveltejs/svelte-loader/blob/master/CHANGELOG.md)
- [rollup-plugin-svelte](https://github.com/sveltejs/rollup-plugin-svelte) is now at version 7.x - with support for relative filenames, better handling of sourcemaps, and consistent `compilerOptions`. Be sure to [checkout the changelog](https://github.com/sveltejs/rollup-plugin-svelte/blob/master/CHANGELOG.md) for breaking changes when upgrading
- [svelte-preprocess](https://github.com/sveltejs/svelte-preprocess) iterated through some 4.6.x releases this month to improve postcss and scss handling and fix sourcemap transformation for typescript users. [More info in the changelog](https://github.com/sveltejs/svelte-preprocess/blob/main/CHANGELOG.md)
- [Sapper](https://github.com/sveltejs/sapper) got some improvements in scroll tracking and handling encoding query parameters. Dynamic imports also now work as expected in browsers that don't support ES modules. These changes from 0.29.0 and a step-by-step migration guide can be found [in the changelog](https://github.com/sveltejs/sapper/blob/master/CHANGELOG.md)
- [prettier-plugin-svelte](https://github.com/sveltejs/prettier-plugin-svelte) version 2 was released. It received an overhaul and comes with a rewrite of the HTML formatting. The output is now much more in line with how standard Prettier formats HTML. Better defaults for `svelteBracketNewLine` and `options-scripts-markup-styles` should now match how the majority of users like to order the code blocks. Additionally, Prettier's `htmlWhitespaceSensitivity` setting is now supported. [More info in the changelog](https://github.com/sveltejs/prettier-plugin-svelte/blob/master/CHANGELOG.md)
New changes to the Svelte Society website include [a new cheat sheet](https://sveltesociety.dev/cheatsheet) for easy access to useful code patterns and some smaller visual fixes across the site. **Want to help make the Svelte Society website ready for prime time**?

title: "What's new in Svelte: March 2021"
description: Call for Svelte Summit Speakers! Improved SSR, non-HTML5 compilation targets, and ESLint TypeScript support
author: Dani Sandoval
authorURL: https://dreamindani.com
---
Lots to cover this month with releases from across the Svelte ecosystem. Most importantly, Svelte Summit Spring 2021 has an [Open Call for Speakers](https://sessionize.com/svelte-summit-spring-2021). **The deadline is March 14** so if you have an idea for a talk, submit it now!
Let's dive into the news 🐬
## What's new in `sveltejs/svelte`
* SSR store handling has been reworked to subscribe and unsubscribe as in DOM mode. SSR stores should work much more consistently now (**3.31.2**, see [custom stores](https://svelte.dev/examples/custom-stores) and [Server-side component API ](https://svelte.dev/docs#run-time-server-side-component-api))
* Multiple instances of the same action are now allowed on an element (**3.32.0**, [example](https://svelte.dev/repl/01a14375951749dab9579cb6860eccde?version=3.32.0))
* The new `foreign` namespace should make it easier for alternative compile targets (like Svelte Native and SvelteGUI) by disabling certain HTML5-specific behaviour and checks (**3.32.0**, [more info](https://github.com/sveltejs/svelte/pull/5652))
* Support for inline comment sourcemaps in code from preprocessors (**3.32.0**)
* Destructured defaults are now allowed to refer to other variables (**3.33.0**, [example](https://svelte.dev/repl/0ee7227e1b45465b9b47d7a5ae2d1252?version=3.33.0))
* Custom elements will now call `onMount` functions when connecting and clean up when disconnecting (**3.33.0**, checkout [this PR](https://github.com/sveltejs/svelte/pull/4522) for an interesting conversation on how folks are using Svelte with Web Components)
* A `cssHash` option has been added to the compiler options to control the classname used for CSS scoping (**3.34.0**, [docs](https://svelte.dev/docs#compile-time-svelte-compile))
* Continued improvement to TypeScript definitions
For a complete list of changes, including bug fixes and links to PRs, check out [the CHANGELOG](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md)
## New from `sveltejs/language-tools`
- For language server clients that don't support `didChangeWatchedFiles`, a fallback file watcher will be used instead
- New highlighting rules for store accessors and element directives (like `bind:` and `class:`)
- HTML tags can now be renamed together
- Mustache tags parsing is now more robust and will provide better intellisense in more situations
Haven't tried the language-tools yet? Check out [Svelte Extension for VSCode](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode) or find a plugin for your favorite IDE!
## Other changes from `sveltejs/*`

- [prettier-plugin-svelte](https://github.com/sveltejs/prettier-plugin-svelte/) released a number of minor versions to address whitespace and comment trimming issues.
- [svelte-preprocess](https://github.com/sveltejs/svelte-preprocess/) bug fixes this month include fixes to postcss transformations and support for both v2 and v3 of `postcss-load-config`
- [sapper](https://github.com/sveltejs/sapper/)'s 0.29.1 release fixes some bad imports in type definitions, updates typings to be compatible with express/polka, and restores hashing of all CSS file names.

<aside><p>Previously: <a href="/blog/whats-the-deal-with-sveltekit">What's the deal with SvelteKit?</a></p></aside>
It's time. After five months and hundreds of commits, you're finally invited to try out the SvelteKit beta. It's not finished — there are a few known bugs and several missing features — but we're really happy with how it's shaping up and can't wait for you to try it.
Starting a new project is easy:
```bash
# create the project
mkdir my-app
cd my-app
npm init svelte@next
# install dependencies
npm install
# start dev server and open a browser tab
npm run dev -- --open
```
You'll find documentation at [kit.svelte.dev/docs](https://kit.svelte.dev/docs). If you have a [Sapper](https://sapper.svelte.dev) app that you'd like to migrate to SvelteKit, you'll find instructions at [kit.svelte.dev/docs/migrating](https://kit.svelte.dev/docs/migrating).
The source code is available at [github.com/sveltejs/kit](https://github.com/sveltejs/kit). Issues and pull requests are disabled while we finish getting our house in order, but we'll be making it fully open in the near future.
## Wait, what is SvelteKit?
Think of it as [Next](https://nextjs.org/) for Svelte. It's a framework for building apps with Svelte, complete with server-side rendering, routing, code-splitting for JS and CSS, adapters for different serverless platforms and so on.
If you're familiar with [Sapper](https://sapper.svelte.dev), SvelteKit is Sapper's successor.
## From Snowpack to Vite
One thing that might seem surprising after the [announcement video](/blog/whats-the-deal-with-sveltekit), in which I waxed lyrical about [Snowpack](https://www.snowpack.dev/), is that SvelteKit uses [Vite](https://vitejs.dev) under the hood. When we tried Snowpack back when we started thinking about what form SvelteKit should take, it was love at first sight.
Snowpack created an entirely new category of dev tooling. Rather than _bundling_ your app in development, as we've been doing with webpack and Rollup for the last several years, Snowpack is an _unbundled dev server_ that uses the browser's native `import` and does 1:1 transformations of things like Svelte components on the fly. As a result you get quick startup, simple caching and instant hot module reloading. Once you experience this way of working, it will ruin you for anything else.
Vite falls into the same category as Snowpack. While Vite 1 wasn't suitable for SvelteKit — it was Vue-centric (Vite and Vue are both created by [Evan You](https://twitter.com/youyuxi)) and made server-side rendering difficult — Vite 2 is framework-agnostic and designed with SSR at the core. It also has powerful features, like CSS code-splitting, that we previously had to implement ourselves. When we evaluated the two technologies side-by-side we were forced to conclude that Vite is a closer match for SvelteKit's requirements and would give us the best chance to deliver the framework of our imaginations.
We owe a deep debt of gratitude to the Snowpack team, both for the close collaboration earlier in development and for lighting the path that web development will take over the next few years. It's a wonderful tool, and you should absolutely try it out.
## Dogfooding as extreme sport
SvelteKit is very much in beta, but that doesn't mean it hasn't been used in production.
My day job is at the New York Times, where I've spent much of the last twelve months working on our [coronavirus tracker](https://www.nytimes.com/interactive/2020/us/coronavirus-us-cases.html). It uses a customised version of the workflow that powers the majority of graphics at the Times, which isn't designed for large multi-page projects. When we decided late last year to create pages for each of the ~3,000 counties in the US, we quickly realised we would need to completely rearchitect the project.
Even though it was far from ready, SvelteKit was the only framework that matched our esoteric requirements. (Anyone who has worked in a newsroom and done battle with their CMS will know what I'm talking about.) Today it powers our [county risk pages](https://www.nytimes.com/interactive/2021/us/tom-green-texas-covid-cases.html) and we're in the process of migrating existing pages to the SvelteKit app.
<aside><p>I am eternally grateful for my coworkers' forbearance.</p></aside>
Using unfinished software to build an app that will be seen by millions of people is a risk, and in general I don't recommend it. But it has enabled us to develop the app much faster, and has made the framework itself much stronger than it otherwise would be.
## The road to 1.0
You can see the list of outstanding issues with the 1.0 milestone on our [issue tracker](https://github.com/sveltejs/kit/issues?q=is%3Aopen+is%3Aissue+milestone%3A1.0). Alongside that work, we plan to upgrade the documentation and add more [adapters](https://kit.svelte.dev/docs/adapters).
Most importantly though, we need your feedback to help us make the best possible app framework. Try it out, and let us know which pieces are missing.
Many thanks to everyone who has tried SvelteKit out despite the 'here be dragons' warnings and lack of documentation; your back-channel feedback has been invaluable. In particular, I want to acknowledge the work of [GrygrFlzr](https://github.com/GrygrFlzr), who maintained unofficial docs and a fork that added Windows support when we lacked it; and [dominikg](https://github.com/dominikg) whose work on [Svite](https://github.com/svitejs/svite) laid essential groundwork for SvelteKit's Vite integration. Both have now been welcomed onto the team.

title: "What's new in Svelte: June 2021"
description: Progress towards SvelteKit 1.0 and tighter TypeScript/Svelte integrations in language tools
author: Dani Sandoval
authorURL: https://dreamindani.com
---
This month, we saw lots of contributions to SvelteKit and its docs. The language tools also got some new features, most notably deeper integration with Svelte files within JavaScript or TypeScript files. Let's jump into the updates...
## New in SvelteKit
- `svelte.config.js` config files are now loaded in ESM format (`.js` instead of `.cjs`).
- AMP pages will now use the rendered CSS, rather than emitted CSS
- `svelte-check` has been added to the TypeScript template ([sveltejs/kit#1556](https://github.com/sveltejs/kit/pull/1556))
- Support for https keypair [sveltejs/kit#1456](https://github.com/sveltejs/kit/pull/1456)
- Now bundling Vite with SvelteKit and using an upgraded version. Remove Vite from your `package.json` if it's there
- Etags for binary responses [sveltejs/kit#1382](https://github.com/sveltejs/kit/pull/1382)
- Renamed `$layout` to `__layout` and `$error` to `__error`
- Removed `getContext` in favor of `request.locals`
- Renamed `.svelte` output directory to `.svelte-kit`. Update your `.gitignore` accordingly
- `trailingSlash: 'never' | 'always' | 'ignore'` is now available in the config. This should make it easier to build sites that work with static hosting providers that expect a trailing slash for `index.html` pages, and provides an escape hatch for anyone that needs more complex behaviour.
## Notable bug fixes in SvelteKit
- `adapter-netlify` got a fix [sveltejs/kit#1467](https://github.com/sveltejs/kit/pull/1467) and new documentation in the readme https://github.com/sveltejs/kit/tree/master/packages/adapter-netlify
- The router will no longer intercept navigation for URLs that the app does not own. This fixes a crash for apps that have `<a>` elements on the page with the same origin but don't share a base path with the app.
- Hash only changes are now handled by the router fixing the browser's "back" navigation between hash changes in some circumstances.
## New in Svelte & Language Tools
- Svelte 3.38.1 and 3.38.2 fixed an issue with hydration that was causing duplicate elements. If you're seeing this in your project, be sure to update the latest version!
- A new TypeScript plugin provides deeper integration with Svelte files within JavaScript or TypeScript files. This includes diagnostics, references and renaming of variables. It comes packaged with the VS Code extension but is turned off by default for now. You can enable it through [this setting](https://github.com/sveltejs/language-tools/tree/master/packages/svelte-vscode#svelteenable-ts-plugin). We encourage you to test it out and [provide feedback](https://github.com/sveltejs/language-tools/issues/580)
- In the latest version of `svelte-check` you can now provide the path to your `tsconfig.json` or `jsconfig.json`. Example: `svelte-check --tsconfig "./tsconfig.json"`. This ensures the diagnostics are only run on files that are referenced in that config. It also runs diagnostics on JavaScript and/or TypeScript files which removes the need to run another check (like `tsc --noEmit`) for non-Svelte files (`svelte-check` version [**1.6.0**](https://github.com/sveltejs/language-tools/releases/tag/svelte-check-1.6.0))
- The VS Code extension and `svelte-check` got a new major release. Previously, properties that had no initializer (`export let foo;`) were only required if the user was using both TypeScript and activated `strict` mode. This is changed now: People using TypeScript, and those using `checkJs` also in JavaScript files, will now always have these properties marked as required (`svelte-check` version [**2.0.0**](https://github.com/sveltejs/language-tools/releases/tag/svelte-check-2.0.0), extension version [**105.0.0**](https://github.com/sveltejs/language-tools/releases/tag/extensions-105.0.0))

title: "What's new in Svelte: July 2021"
description: Keeping cool with fixes, TypeScript tooling and tonnes of new features
author: Dani Sandoval
authorURL: https://dreamindani.com
---
As the northern hemisphere heats up, Svelte has stayed cool with lots of performance and bug fixes, better TypeScript support, and lots of new components & tools from around the ecosystem. Let's take a peek 👀
## New in SvelteKit
- `adapter-node` now precompresses assets using gzip & brotli ([#1693](https://github.com/sveltejs/kit/pull/1693))
- Support for TypeScript transpilation has been added to the `svelte-kit package` tooling ([#1633](https://github.com/sveltejs/kit/pull/1633))
- Improved caching defaults in `adapter-node` ([#1416](https://github.com/sveltejs/kit/pull/1416))
- Allow configuring Rollup output options ([#1572](https://github.com/sveltejs/kit/pull/1572))
- Fixed usage of SSL with HMR ([#1517](https://github.com/sveltejs/kit/pull/1517))
## Features & bug fixes from around svelte/*
- [Svelte 3.38.3](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md#3383) (released June 22) includes a bunch of performance and bug fixes - including hydration optimizations, `this` preservation in bubbled events, and more!
- The latest language tools releases added support for prop renaming from outside of a component, PostCSS syntax grammar, and a `.d.ts` output target in `svelte2tsx` which can be used to create type definitions from Svelte files.
- Also in language tools, some long-awaited experimental features for enhanced TypeScript support were added - including explicitly typing all possible component events or slots, and using generics. Have a look at [the RFC](https://github.com/sveltejs/rfcs/pull/38) for more details and leave feedback in [this issue](https://github.com/sveltejs/language-tools/issues/442) if you are using it.
- `svelte-scroller` got some quality-of-life fixes in 2.0.7 - fixing an initial width bug and updating its `index` more conservatively
## Coming soon to Svelte
- Constants in markup ([RFC](https://github.com/sveltejs/rfcs/blob/master/text/0000-markup-constants.md)): Adds a new `{@const ...}` tag that defines a local constant ([PR](https://github.com/sveltejs/svelte/pull/6413))

title: "What's new in Svelte: August 2021"
description: Shadow DOM, export and await - oh my!
author: Dani Sandoval
authorURL: https://dreamindani.com
---
From The Changelog ([JS Party Ep. 182](https://changelog.com/jsparty/182)) to Svelte Radio (Episodes [29](https://share.transistor.fm/s/adc23e84) and [30](https://share.transistor.fm/s/6316622d)), it seems that folks couldn't help but talk about Svelte, this month! Also, shadow DOM support and new export and await functionality are new in Svelte.
## New in Svelte
July was the most active month for the Svelte core repo since late 2019 as we really worked to reduce the number of outstanding PRs and saw the release of Svelte 3.39.0, 3.40.0, and 3.41.0. Tons of bug fixes were added as well as the following new features:
- The `|trusted` event modifier allows you to check if an event is trusted before it's called ([#6137](https://github.com/sveltejs/svelte/issues/6137))
- The new `svelte/ssr` package to support work on improving SvelteKit SSR ([#6416](https://github.com/sveltejs/svelte/pull/6416))
- A new `errorMode` compiler option to support improved preprocessing of TypeScript files ([#6194](https://github.com/sveltejs/svelte/pull/6194))
- You can now specify a `ShadowRoot` as the `target` when creating a component - making it possible to render Svelte components inside the shadow DOM ([#5869](https://github.com/sveltejs/svelte/issues/5869))
- The `export { ... } from` ([#2214](https://github.com/sveltejs/svelte/issues/2214)), `export let { ... } =` ([#5612](https://github.com/sveltejs/svelte/issues/5612)) and `{#await ... then/catch}` ([#6270](https://github.com/sveltejs/svelte/issues/6270)) syntaxes are all now supported in Svelte components
For a full list of features and bug fixes, check out the [Svelte changelog](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md).
## SvelteKit Updates
- `prerender.force` is now `prerender.onError` which lets you fine-tune which errors fail the build and which do not ([#2007](https://github.com/sveltejs/kit/pull/2007))
- esbuild's configuration is now exposed for use with SvelteKit adapters ([#1914](https://github.com/sveltejs/kit/pull/1914))
- Error messages are friendlier now for common config errors ([#1910](https://github.com/sveltejs/kit/pull/1910)) and compiler errors ([#1827](https://github.com/sveltejs/kit/pull/1827))
- Cookies will only be passed through if the target host is the same as the SvelteKit application or a more specific subdomain of it ([#1847](https://github.com/sveltejs/kit/pull/1847))
- index.js exports will now be changed to directory exports when packaging - making for nicer imports ([#1905](https://github.com/sveltejs/kit/pull/1905))
- Vite.js's `mode` is now exposed from `$app/env` ([#1789](https://github.com/sveltejs/kit/pull/1789))
- Better types across the board ([#1778](https://github.com/sveltejs/kit/pull/1778), [#1791](https://github.com/sveltejs/kit/pull/1791), [#1646](https://github.com/sveltejs/kit/pull/1646))
To see all updates to SvelteKit, check out the [SvelteKit changelog](https://github.com/sveltejs/kit/blob/master/packages/kit/CHANGELOG.md).
## Features & bug fixes from around svelte/*
- Language Tools now better support the "Workplace Trust" functionality (used in VS Code)
- In svelte2tsx, ambient type declarations are now renamed to avoid conflicting declarations in the future. Users are now expected to provide the ambient type definitions themselves - fixing JS output
- Sapper released v0.29.2 which fixes regex routes, status codes when requesting a directory, and exports when a user has not provided a `base` tag ([changelog](https://github.com/sveltejs/sapper/blob/master/CHANGELOG.md))

title: "What's new in Svelte: September 2021"
description: StackOverflow's most loved web framework
author: Dani Sandoval
authorURL: https://dreamindani.com
---
This month, Svelte was [voted StackOverflow's most loved web framework](https://insights.stackoverflow.com/survey/2021#section-most-loved-dreaded-and-wanted-web-frameworks), Tan Li Hau [talked to Svelte Radio](https://share.transistor.fm/s/84c7521b) about his [Svelte-filled YouTube channel](https://www.youtube.com/channel/UCbmC3HP3FaAFdcZkui8YoMQ), and SvelteKit made even more progress towards its 1.0 release!
## New in Svelte
- `use:actions` can now be used on `<svelte:body>` (**3.42.0**)
- `HTMLElement`, `SVGElement` (**3.42.2**) and `BigInt` (**3.42.3**) are now known globals
- There is less code in Svelte's output thanks to the following improvements in **3.42.2**:
- Whitespace is now collapsed in class and style attributes
- Hydrated components have been updated to only rely upon helpers for creating the types of elements present in the component
- Scaling is now accounted for in `flip` animations (**3.42.2**)

For a full list of features and bug fixes, check out the [Svelte changelog](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md).
## SvelteKit Updates
Svelte maintainers are [looking for help getting SvelteKit to 1.0](https://github.com/sveltejs/kit/issues/2100). We've knocked out over 100 issues that were on the 1.0 milestone. There's only a couple dozen left and we'd love a hand making that list a bit shorter!
If you'd like to help, please consider working on any of the [1.0 milestone issues](https://github.com/sveltejs/kit/issues?q=is%3Aopen+is%3Aissue+milestone%3A1.0).
The focus this past month was on continuing to iron out any kinks, with well over 100 PRs merged. A few new features went in as well...
- SvelteKit will now detect if a prerendered app is trying to access a query parameter and return an error instead of failing silently ([#2104](https://github.com/sveltejs/kit/pull/2104))
- `adapter-node` now lets you [add the Kit middleware to your own server](https://kit.svelte.dev/faq#integrations) for use with other middleware. You can also [add middleware in dev mode](https://kit.svelte.dev/faq#how-do-i-use-x-with-sveltekit-how-do-i-use-middleware) with more improvements to come in this area
- The new [`sequence` helper lets you chain together multiple `handle` calls](https://kit.svelte.dev/docs/modules#sveltejs-kit-hooks)
- A new [`handleError` hook](https://kit.svelte.dev/docs/hooks#handleerror) gives you the option to send data to an error tracking service, or to customise the formatting before printing the error to the console.
- `adapter-node` can now listen on socket path ([#2048](https://github.com/sveltejs/kit/pull/2048))

title: "What's new in Svelte: October 2021"
description: A whole year of "What's new in Svelte"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
Hey y'all 👋 It's been 1 year since "What's new in Svelte" started being cross-posted to the Svelte blog. I wanted to take this moment at the top to thank all of you for reading and for all the contributors every month. From the maintainers to everyone who posts their work in the Discord and Reddit, it's amazing to witness all the effort that goes into making the Svelte community great.
Keep up the good work, everyone! Now, let's dive into this month's news...
## New around Svelte
- New additions to Svelte's export map now expose no-op versions of lifecycle functions for SSR (Svelte **3.43.0**)
- Custom components with a `src` attribute no longer break `svelte-native` builds (Svelte **3.42.4**)
- Svelte plugin users without [the TypeScript plugin](https://www.npmjs.com/package/typescript-svelte-plugin) enabled will now be prompted to enable it. It enhances TypeScript and JavaScript files with additional intellisense to interact with Svelte files. [Please leave feedback](https://github.com/sveltejs/language-tools/issues/580) if you are using it (Svelte extensions **105.4.0**)
- Event modifiers have been added to intellisense as autocomplete and hover info (Svelte extensions **105.4.0**)
- TypeScript users no longer have to strictly separate type imports and value imports when using Svelte version 3.39 or higher and `svelte-preprocess` version 4.9.5 or higher. This means you can now write `import { MyInterface, myValue } from './somewhere'` instead of `import type { MyInterface } from './somewhere'; import { myValue } from './somewhere'`. Huge thanks to community member [@SomaticIT](https://github.com/SomaticIT) who mainly implemented this!
For a full list of features and bug fixes, check out the [Svelte changelog](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md).
## SvelteKit Updates
Nearly 100 PRs committed again this past month, but there's still lots to do and Svelte maintainers are [looking for help getting SvelteKit to 1.0](https://github.com/sveltejs/kit/issues/2100). Antony said it well in a [recent comment](https://github.com/sveltejs/kit/issues/2100#issuecomment-895446285) on the issue:
> If you think you are too n00b to contribute (you're not), then add tests, or write tests for the feature you want to add, before you add it! Start small, and learn the codebase that way.
If you'd like to help, please consider working on any of the [1.0 milestone issues labeled with "help wanted"](https://github.com/sveltejs/kit/issues?q=is%3Aopen+is%3Aissue+milestone%3A1.0+label%3A%22help+wanted%22).
Notable SvelteKit improvements this month include...
- Service workers are now allowed to access files using the `$lib` alias ([#2326](https://github.com/sveltejs/kit/pull/2326))
- Svelte libraries should now work out-of-the-box without any Vite configuration ([#2343](https://github.com/sveltejs/kit/pull/2343))
- Improvements to package exports field ([#2345](https://github.com/sveltejs/kit/pull/2345) and [#2327](https://github.com/sveltejs/kit/pull/2327))
- [breaking] The `prerender.pages` config option has been renamed to `prerender.entries` ([#2380](https://github.com/sveltejs/kit/pull/2380))
- A new generic argument has been added to allow typing Body from hooks ([#2413](https://github.com/sveltejs/kit/pull/2413))
- The `svelte` field will be added to package.json when running the package command ([#2431](https://github.com/sveltejs/kit/pull/2431))
- [breaking] The `context` parameter of the load function was renamed to `stuff` ([#2439](https://github.com/sveltejs/kit/pull/2439))
- Added an `entryPoint` option for building a custom server with `adapter-node` ([#2414](https://github.com/sveltejs/kit/pull/2414))
- `vite-plugin-svelte` improved support for [useVitePreprocess](https://github.com/sveltejs/vite-plugin-svelte/blob/main/docs/config.md#usevitepreprocess), which uses Vite to automatically preprocess TypeScript, PostCSS, Scss, etc in Svelte components ([#173](https://github.com/sveltejs/vite-plugin-svelte/pull/173))

title: "What's new in Svelte: November 2021"
description: Over 5000 stars to light up the showcase
author: Dani Sandoval
authorURL: https://dreamindani.com
---
With SvelteKit crossing the [80% complete mark](https://github.com/sveltejs/kit/milestone/2), over [5000 stars](https://github.com/sveltejs/kit) on GitHub, and now having more usage than Sapper, there's never been a better time to try it out! Many in the community have, making for quite a large showcase this month...
Also, don't miss out on [Svelte Summit](https://sveltesummit.com/) on November 20th - featuring speakers from around the world. Keep an eye out for a watch party in your area 👀
Now onto what's new!
## New in Svelte and SvelteKit
- [svelte.dev](https://svelte.dev/) now runs on SvelteKit alongside [sveltesociety.dev](https://sveltesociety.dev). svelte.dev is a relatively complicated site with live code editing, authentication, and a markdown-based blog - making it a great way for us to really test out SvelteKit
- A new compiler option, `enableSourcemap`, provides more control over the compiler output for JS and CSS sourcemaps (**3.44.0**). With this new feature, SvelteKit and the Vite Svelte plugin can now properly handle environment variables in `.svelte` templates (See [sveltejs/kit#720](https://github.com/sveltejs/kit/issues/720) and [sveltejs/vite-plugin-svelte#201](https://github.com/sveltejs/vite-plugin-svelte/pull/201))
- The Svelte Language Tools now support reading the configuration of the VS Code CSS settings ([#1219](https://github.com/sveltejs/language-tools/issues/1219))
- `vite-plugin-svelte` added a new `experimental.prebundleSvelteLibraries` option that makes it much faster to load Svelte libraries with many components like icon libraries and UI frameworks. The option can be set in the root of `svelte.config.js`. Please test it out and give us feedback!
- SvelteKit will only route endpoints on the client, unless marked as `rel="external"` - reducing the size of the client JS and making it easier to refactor the router in the future ([2656](https://github.com/sveltejs/kit/pull/2656))
- SvelteKit no longer supports Node 12 ([2604](https://github.com/sveltejs/kit/pull/2604))
- SvelteKit was upgraded from Vite 2.6.0 to Vite 2.6.12 fixing an issue where Vite would corrupt the Svelte runtime (https://github.com/vitejs/vite/issues/4306). It also included two fixes from the SvelteKit team to avoid or make diagnosing Vite issues in SvelteKit templates easier (https://github.com/vitejs/vite/pull/5192 and https://github.com/vitejs/vite/pull/5193). Vite 2.7 is currently available in beta with additional fixes for SSR
To see all updates to Svelte and SvelteKit, check out the [Svelte](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md) and [SvelteKit changelog](https://github.com/sveltejs/kit/blob/master/packages/kit/CHANGELOG.md), respectively.

description: "Faster builds with SvelteKit and a much anticipated REPL feature"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
Happy new year, Svelte Community! Lots to share this month across Svelte, SvelteKit, Language Tools and the Showcase. Thanks to everyone who made 2021 a great year to use Svelte. Looking forward to the next one 🚀
## What's new in SvelteKit
- `@sveltejs/adapter-static` for SvelteKit now has a `precompress` option to make brotli compression of assets and pages easier to do out of the box ([#3079](https://github.com/sveltejs/kit/pull/3079))
- Concurrency mode in SvelteKit will now prerender pages in parallel ([#3120](https://github.com/sveltejs/kit/pull/3120)). It is enabled by default in `1.0.0-next.205` and later
- CSS is now automatically included before JS for improved page performance ([d13efe](https://github.com/sveltejs/kit/commit/d138efe21692f5925f1e89afc0a33f42d6a1a711))
- A new config option adds the ability to disable service worker registration to do your own custom registration ([#2988](https://github.com/sveltejs/kit/pull/2988))
- SSR route-splitting is here - breaking monolithic builds into smaller pieces for improved startup and routing performance ([#2931](https://github.com/sveltejs/kit/pull/2931))
- `request.origin/path/query` is now `request.url` - simplifying the config and page `load` functions ([#3126](https://github.com/sveltejs/kit/pull/3126))
- After the [update to Vite 2.7](https://github.com/sveltejs/kit/pull/3018), SvelteKit users are [reporting significant performance improvements](https://www.reddit.com/r/sveltejs/comments/rljhfc/sveltekit_massive_compiler_improvement_by/) and loading third-parties libraries in SSR has also been greatly improved
- SvelteKit server will now automatically restart when the config files is changed ([vite-plugin-svelte#237](https://github.com/sveltejs/vite-plugin-svelte/pull/237))
## Other new bits from `svelte/*`
- [Svelte 3.44.3](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md#3443) is out with a few bug fixes in the binding and loop code
- Svelte Language Tools has introduced support for the then/catch shorthands from Svelte 3.41 and TypeScript's "go to" functionality ([105.8.0 and later](https://github.com/sveltejs/language-tools/releases/tag/extensions-105.8.0))
- The Svelte REPL got a nice upgrade as well - letting you delete saved REPLs. Try it out by logging in at [svelte.dev/apps](https://svelte.dev/apps)

title: "Accelerating Svelte's Development"
description: "Scaling the team, building partnerships, and growing the community"
author: Ben McCann
authorURL: https://www.benmccann.com/
---
[Svelte](/) is a frontend framework for building fast reactive web apps with less code. If youre new here, [check out the tutorial](/tutorial) or [examples](/examples) to get a feel for it.
Svelte was [launched 5 years ago](https://news.ycombinator.com/item?id=13069841) and has [come a long way in the time since](https://www.youtube.com/watch?v=YeY5M29-WcY). In 2021, as usage more than doubled, it was voted the [most loved](https://insights.stackoverflow.com/survey/2021#section-most-loved-dreaded-and-wanted-web-frameworks) framework with the [most satisfied](https://2020.stateofjs.com/en-US/technologies/front-end-frameworks/) developers in a pair of surveys. Alongside high-profile companies like The New York Times, Apple, Spotify, Square, Rakuten, Bloomberg, Reuters, Ikea, Brave, and countless others, Svelte is used to power everything from hobby projects to embedded systems interfaces.
To help developers build fully-featured applications with Svelte without worrying about the hard parts, weve been developing the [SvelteKit](https://kit.svelte.dev/) application framework. Were moving quickly towards a [stable 1.0 release](https://github.com/sveltejs/kit/issues?q=is%3Aopen+is%3Aissue+milestone%3A1.0) with the help of early adopters who have already downloaded SvelteKit almost one million times.
## Scaling the team
Rich Harris, Sveltes creator, has [joined Vercel to work on Svelte full-time](https://vercel.com/blog/vercel-welcomes-rich-harris-creator-of-svelte). Were incredibly excited to have Richs level of involvement in Svelte increase even more and have him steward Svelte into the future.
Svelte has been made possible by the work of a large, dedicated community. Svelte has added numerous core maintainers over the course of the pandemic, including three this past week. In alphabetical order:
- [benmccann](https://github.com/benmccann) - primary maintainer of SvelteKit for much of 2021
- [bluwy](https://github.com/bluwy) - major contributor across SvelteKit, vite-plugin-svelte, and Vite
- [dominikg](https://github.com/dominikg) - creator of vite-plugin-svelte
- [dummdidumm](https://github.com/dummdidumm) - maintainer of language-tools, which includes the VS Code extension and `svelte-check`
- [ehrencrona](https://github.com/ehrencrona) - contributor to SvelteKit and uses Svelte at work
- [geoffrich](https://github.com/geoffrich) - has driven efforts to improve the accessibility of the Svelte site and documentation
- [GrygrFlzr](https://github.com/GrygrFlzr) - holds a unique status as a maintainer of both SvelteKit and Vite
- [Halfnelson](https://github.com/Halfnelson) - creator of svelte-native
- [ignatiusmb](https://github.com/ignatiusmb) - regular SvelteKit contributor especially to TypeScript support
- [jasonlyu123](https://github.com/jasonlyu123) - maintainer of language-tools, which includes the VS Code extension and `svelte-check`
- [kaisermann](https://github.com/kaisermann) - creator of svelte-preprocess
- [RedHatter](https://github.com/RedHatter) - creator of Svelte Devtools
- [rixo](https://github.com/rixo) - creator of svelte-hmr
Svelte began accepting donations via [OpenCollective](https://opencollective.com/svelte) last year and has now had over $60,000 donated to-date with [Cohere](https://cohere.ai/) giving $10,000 just today. We hope that these funds will allow existing maintainers to spend more time on Svelte or that the funds could otherwise support Svelte on a part-time or contract basis, which we will continue to investigate.
## Partnerships
Multiple major cloud vendors are stepping up to make deploying SvelteKit applications anywhere a seamless experience. As a result of Richs new job, SvelteKit will soon run on [Vercel Edge Functions](https://vercel.com/features/edge-functions). Netlify has made [big contributions](https://github.com/sveltejs/kit/pull/2113) to the SvelteKit Netlify adapter and also [updated](https://github.com/dependents/node-precinct/pull/88) their zip-it-and-ship-it tool to better support SvelteKit. The recent [Cloudflare Pages launch](https://blog.cloudflare.com/cloudflare-pages-goes-full-stack/) featured SvelteKit as a day one partner via a [new adapter](https://github.com/sveltejs/kit/tree/master/packages/adapter-cloudflare) written by Svelte maintainers [pngwn](https://twitter.com/evilpingwin) and [lukeed](https://twitter.com/lukeed05), the latter of whom joined Cloudflare in 2021. [Begin](https://begin.com) created a [SvelteKit adapter](https://github.com/architect/sveltekit-adapter) for [Architect](https://arc.codes) apps. And community members have [contributed adapters](https://sveltesociety.dev/components#adapters) for environments such as Firebase and Deno, showcasing SvelteKits ability to run wherever JavaScript does.
Weve also been working closely with the [Vite](https://vitejs.dev) team to iron out SSR issues uncovered by SvelteKit users. Vite is the build tool that makes the SvelteKit developer experience possible, and thanks to hard work from a contributor base that includes representatives of multiple frameworks, recent releases have solved almost all the issues weve been tracking as SvelteKit 1.0 release blockers.
## A growing community
[SvelteSociety](https://sveltesociety.dev/) just hosted the [4th Svelte Summit](https://sveltesummit.com/) — [read a summary here](https://svelte.dev/blog/whats-new-in-svelte-december-2021#what-happened-at-svelte-summit) — and Kevin Åberg Kultalahti is [going full-time to lead SvelteSociety](https://twitter.com/kevmodrome/status/1463151477174714373). In addition to hosting Svelte Summit, Kevin and SvelteSociety host and manage the [Svelte Radio podcast](https://www.svelteradio.com/), the [SvelteSociety YouTube channel](https://www.youtube.com/SvelteSociety), and the [Svelte subreddit](https://www.reddit.com/r/sveltejs). SvelteSociety has become the home of all things related to the Svelte community, with the sveltejs/community and sveltejs/integrations repos being retired in favor of [sveltesociety.dev](https://sveltesociety.dev/), which has been redesigned and rebuilt in SvelteKit. In October [Brittney Postma](https://github.com/brittneypostma), [Willow aka GHOST](https://ghostdev.xyz), [Steph Dietz](https://github.com/StephDietz), and [Gen Ashley](https://twitter.com/coderinheels) founded [Svelte Sirens](https://sveltesirens.dev/), a group for women & non-binary community members and their allies.
Hundreds of developers join the Svelte Discord every week to chat about Svelte. You may have noticed that, as of recently, some members of the server have purple names. These are people with the ambassadors role, which was created to recognise some of the communitys most valued members and help manage the demands of a rapidly growing community. Svelte ambassadors are people who are well known for their helpfulness and contributions and for upholding Sveltes reputation as a friendly, welcoming community, and were deeply grateful for their involvement. The initial ambassadors in alphabetical order are:
- [babichjacob](https://github.com/babichjacob)
- [brady fractal](https://github.com/FractalHQ)
- [brittney postma](https://github.com/brittneypostma)
- [d3sandoval](https://github.com/d3sandoval)
- [geoffrich](https://github.com/geoffrich)
- [kev](https://github.com/kevmodrome)
- [puru](https://github.com/PuruVJ)
- [rainlife](https://github.com/stephane-vanraes)
- [rmunn](https://github.com/rmunn)
- [stolinski](https://github.com/stolinski)
- [swyx](https://github.com/sw-yx)
- [theo](https://github.com/theo-steiner)
Were also testing out [GitHub discussions on SvelteKit](https://github.com/sveltejs/kit/discussions) and may bring this to other repos in the Svelte organization if feedback is positive.
## Things to watch
SvelteKit is continuing to progress towards 1.0 and, in just the past week, we have added major features like [improved client-only rendering](https://github.com/sveltejs/kit/pull/2804), [routing hooks](https://github.com/sveltejs/kit/pull/3293), and [the ability to pass data from child components to layouts](https://github.com/sveltejs/kit/pull/3252) (e.g. to support easier management of `<meta>` tags). We're currently working on a number of other high priority items such as discussing API designs for features like streaming and file uploads and contributing to the upcoming Vite 2.8 release.
While a lot of effort has been going into SvelteKit recently, we continue to progress the entire ecosystem. [Svelte 3.46.0](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md#3460) was one of our biggest releases in awhile with two major new features added: [constants in markup](https://github.com/sveltejs/rfcs/blob/master/text/0007-markup-constants.md) and [style directives](https://github.com/sveltejs/rfcs/blob/master/text/0008-style-directives.md).
Svelte and SvelteKits trajectories have been accelerated by the numerous investments above and there will be many more updates to come — subscribe to the [blog](/blog) via [RSS](https://svelte.dev/blog/rss.xml) or check monthly to be the first to get them.

title: "What's new in Svelte: March 2022"
description: "Svelte Summit Spring is coming... and page endpoints are here!"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
Just announced: [Svelte Summit Spring](https://www.sveltesummit.com/) will be taking place on April 30, 2022. The 5th Virtual Svelte Conference is [looking for speakers](https://www.sveltesummit.com/#speakers) and [sponsors](https://www.sveltesummit.com/sponsors)... so it's time to dust off those proposals!
Also, some long-requested features were added to SvelteKit this month... including page endpoints! This change in how the `load` function works makes it easier to fetch data required for basic pages, redirect from POST responses and handle 404s and other errors.
More on that and other new features and fixes below!
## What's new in SvelteKit
- The docs are now searchable and multipage with type definitions and hoverable code examples - Check them out at [kit.svelte.dev/docs](https://kit.svelte.dev/docs/)
- Page endpoints significantly decrease the boilerplate needed when loading a page ([Issue](https://github.com/sveltejs/kit/issues/3532), [PR](https://github.com/sveltejs/kit/pull/3679), [Docs](https://kit.svelte.dev/docs/routing#endpoints-page-endpoints))
- Application versioning and update detection support lets you determine what to do when a route fails to load after an app update ([Issue](https://github.com/sveltejs/kit/issues/87), [PR](https://github.com/sveltejs/kit/pull/3412), [Docs](https://kit.svelte.dev/docs/configuration#version))
- A new option in `npm init svelte@next` will now set up Playwright automatically for testing ([PR](https://github.com/sveltejs/kit/pull/4056))
**Breaking Changes**
- The `target` option is no longer available. Instead, the `init` script hydrates its `parentNode` ([#3674](https://github.com/sveltejs/kit/pull/3674))
- App-level types now live in the `App` namespace which allows you to type global types like `Stuff` or `Session` ([#3670](https://github.com/sveltejs/kit/pull/3670))
- `JSONString` is now `JSONValue` ([#3683](https://github.com/sveltejs/kit/pull/3683))
- `createIndexFiles` has been removed — it is now controlled by the `trailingSlash` option ([#3801](https://github.com/sveltejs/kit/pull/3801))
- SvelteKit will no longer exclude root-relative external links from prerendering, which will cause 404s if these URLs are intended to be served by a separate app. Use a custom [`prerender.onError`](https://kit.svelte.dev/docs/configuration#prerender) handler if you need to ignore them ([#3826](https://github.com/sveltejs/kit/pull/3826))
## New in Language Tools
- Accessing properties in markups has been improved in the Svelte language tools ([105.12.0](https://github.com/sveltejs/language-tools/releases/tag/extensions-105.12.0)) - working around some known issues with autocomplete ([#538](https://github.com/sveltejs/language-tools/issues/538) / [#1302](https://github.com/sveltejs/language-tools/issues/1302))

title: "What's new in Svelte: April 2022"
description: "Goodbye fallthrough routes, hello param validators!"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
This month, we felt a shift in the way SvelteKit handles page properties. The last holdout of the use-cases that required fallthrough routes, validating parameter properties, has been replaced by a more specific solution.
More on that, and what else is new in Svelte, as we dive in...
## What's new in SvelteKit
- Param matchers allow you to check if a url parameter matches before rendering a page - replacing the need for fallthrough routes for this purpose ([Docs](https://kit.svelte.dev/docs/routing#advanced-routing-matching), [#4334](https://github.com/sveltejs/kit/pull/4334))
- Explicit redirects can now be handled directly from endpoints ([#4260](https://github.com/sveltejs/kit/pull/4260))
- `svelte-kit sync` ([#4182](https://github.com/sveltejs/kit/pull/4182)), TypeScript 4.6 ([#4190](https://github.com/sveltejs/kit/pull/4190)) and Vite 2.9 were released - adding non-blocking dependency optimization and experimental CSS source maps in dev mode as well as a number of bug fixes contributed by the SvelteKit team ([#4468](https://github.com/sveltejs/kit/pull/4468))
**New Config Options**
- `outDir` fixes path issues in monorepos and other situations where the desired output directory is outside the project directory ([Docs](https://kit.svelte.dev/docs/configuration#outdir), [#4176](https://github.com/sveltejs/kit/pull/4176))
- `endpointExtensions` prevents files other than .js and .ts files from being treated as endpoints, unless you specify endpointExtensions ([Docs](https://kit.svelte.dev/docs/configuration#endpointextensions), [#4197](https://github.com/sveltejs/kit/pull/4197))
- `prerender.default` lets you prerender every page without having to write `export const prerender = true` in every page file ([Docs](https://kit.svelte.dev/docs/configuration#prerender), [#4192](https://github.com/sveltejs/kit/pull/4192))
**Breaking Changes**
- Fallthrough routes have been removed. For migration tips, check out the PR ([#4330](https://github.com/sveltejs/kit/pull/4330))
- `tabindex="-1"` is only added to `<body>` during navigation ([#4140](https://github.com/sveltejs/kit/pull/4140) and [#4184](https://github.com/sveltejs/kit/pull/4184))
- Adapters are now required to supply a `getClientAddress` function ([#4289](https://github.com/sveltejs/kit/pull/4289))
- `InputProps` and `OutputProps` can now be typed separately in generated `Load` ([#4305](https://github.com/sveltejs/kit/pull/4305))
- The `\$` character is no longer allowed in dynamic parameters ([#4334](https://github.com/sveltejs/kit/pull/4334))
- `svelte-kit package` has been marked as experimental so changes to it after Kit 1.0 will not be considered breaking ([#4164](https://github.com/sveltejs/kit/pull/4164))
## New across the Svelte ecosystem
- Svelte: Lots of new types for TypeScript and Svelte plugin users - including `style:` directives and Svelte Actions (**3.46.4** and **3.46.5**)
- Language Tools: Svelte project files are now importable/findable through references without having them imported in a TS file ([105.13.0](https://github.com/sveltejs/language-tools/releases/tag/extensions-105.13.0))
- Language Tools: Region folding is now supported in html with `<!--#region-->`/`<!--#endregion-->` ([105.13.0](https://github.com/sveltejs/language-tools/releases/tag/extensions-105.13.0))

- Netlify Edge Functions ([#4657](https://github.com/sveltejs/kit/pull/4657)) and the Vercel build output API ([#4663](https://github.com/sveltejs/kit/pull/4663)) are now supported
- Custom `load` dependencies, array of strings representing URLs the page depends on, are now available when loading routes ([Docs](https://kit.svelte.dev/docs/loading#output-dependencies), [#4536](https://github.com/sveltejs/kit/pull/4536))
**Breaking Changes**
- Validators are now called "matchers" ([Docs](https://kit.svelte.dev/docs/routing#advanced-routing-matching), [#4358](https://github.com/sveltejs/kit/pull/4358))
- `__layout.reset` has been replaced by named layouts - which have much configurability for shared layout elements ([Docs](https://kit.svelte.dev/docs/layouts#named-layouts), [#4388](https://github.com/sveltejs/kit/pull/4388))
- Prerendering is now skipped for `rel="external"` links ([#4545](https://github.com/sveltejs/kit/pull/4545))

title: "What's new in Svelte: June 2022"
description: "Cancellable dispatched events, deeper {@const} declarations and more!"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
With last month's [Svelte Summit](https://www.youtube.com/watch?v=qqj2cBockqE) behind us, we're ready to apply everything we learned in this new month of June! Also new this month are some quality-of-life changes to `createEventDispatcher`, `@const` declarations and tons of progress toward SvelteKit 1.0.
Let's dive in!
## What's new in Svelte
- Custom events can now be cancelled in the `createEventDispatcher` function (**3.48.0**, [Docs](https://svelte.dev/docs#run-time-svelte-createeventdispatcher), [PR](https://github.com/sveltejs/svelte/pull/7064))
- The `{@const}` tag can now be used in `{#if}` blocks to conditionally define variables (**3.48.0**, [Docs](https://svelte.dev/docs#template-syntax-const), [PR](https://github.com/sveltejs/svelte/pull/7451))
- Lots of bug fixes across `<svelte:element>`, animations and various DOM elements. Check out the [CHANGELOG](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md#3480) for a deeper dive!
## What's new in SvelteKit
- Vite 2.9.9 was released as one of the last Vite 2 releases. The Svelte team has been hard at work contributing to the Vite 3 release to make the integration between SvelteKit and Vite smoother than ever ([Vite 3.0 Milestone](https://github.com/vitejs/vite/milestone/5))
- `config.kit.alias` lets you more easily declare a custom alias to replace values in `import` statements ([Docs](https://kit.svelte.dev/docs/configuration#alias), [PR](https://github.com/sveltejs/kit/pull/4964))
- Pages marked for prerendering will now fail during SSR at runtime ([PR](https://github.com/sveltejs/kit/pull/4812))
**Breaking Changes**
- Node 14 is no longer supported ([PR](https://github.com/sveltejs/kit/pull/4922))
- Requests to `/favicon.ico` will no longer be suppressed and will instead be handled as a valid route ([PR](https://github.com/sveltejs/kit/pull/5046))
- AMP support has been moved to a separate `@sveltejs/amp` package ([Docs](https://kit.svelte.dev/docs/seo#manual-setup-amp), [PR](https://github.com/sveltejs/kit/pull/4710))
- Generated types are now written to `_types` directories - update your imports accordingly ([PR](https://github.com/sveltejs/kit/pull/4705))
- `%svelte.head%` and `%svelte.body%` are now `%sveltekit.head%` and `%sveltekit.body%` in `app.html` ([Docs](https://kit.svelte.dev/docs/migrating#project-files-src-template-html), [PR](https://github.com/sveltejs/kit/pull/5016/))
- `LoadInput` is now `LoadEvent`
- Dropped support for Wrangler 1 in favor of Wrangler 2 ([PR](https://github.com/sveltejs/kit/pull/4887))

title: "What's new in Svelte: July 2022"
description: "Faster SSR, language tools improvements and a new paid contributor!"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
From faster SSR to support for Vitest and Storybook in SvelteKit, there's a lot to cover in this month's newsletter...
So let's dive in!
## OpenCollective funding drives Svelte forward
Svelte supporters have donated approximately $80,000 to [the project on OpenCollective](https://opencollective.com/svelte). We're happy to share that the funds are being drawn on to move Svelte forward in a meaningful way. **[@gtm-nayan](https://github.com/gtm-nayan)** has begun triaging and fixing SvelteKit issues this past month as a paid contributor to the project to help us get SvelteKit to a 1.0 level of stability! @gtm-nayan has been an active member of the Svelte community for quite some time and is well known for writing the bot that helps keep our Discord server running. We're happy that this funding has allowed Svelte to get much more of his time.
We will also be utilizing OpenCollective funds to allow Svelte core maintainers to attend [Svelte Summit](https://www.sveltesummit.com/) in person this fall. Thanks to everyone who has donated so far!
## What's new in Svelte & Language Tools
- [learn.svelte.dev](https://learn.svelte.dev/) is a new way to learn Svelte and SvelteKit from the ground up that is currently in development
- Faster SSR is coming in the next Svelte release. A PR two years in the making, resulting in up to 3x faster rendering in some benchmarking tests! ([PR](https://github.com/sveltejs/svelte/pull/5701))
- "Find File References" ([0.14.28](https://github.com/sveltejs/language-tools/releases/tag/language-server-0.14.28)) and "Find Component References" ([0.14.29](https://github.com/sveltejs/language-tools/releases/tag/language-server-0.14.29)) in the latest versions of the Svelte extension shows where Svelte files and components have been imported and used ([Demo](https://twitter.com/dummdidumm_/status/1532459709604716544/photo/1))
- The Svelte extension now supports CSS path completion ([0.14.29](https://github.com/sveltejs/language-tools/releases/tag/language-server-0.14.29))
## What's new in SvelteKit
- Introduced `@sveltejs/kit/experimental/vite` which allows SvelteKit to interoperate with other tools in the Vite ecosystem like Vitest and Storybook ([#5094](https://github.com/sveltejs/kit/pull/5094)). Please [leave feedback](https://github.com/sveltejs/kit/issues/5184) as to whether the feature works and is helpful as we consider taking it out of experimental and making `vite.config.js` required for all users
- Streaming in endpoints is now supported ([#3419](https://github.com/sveltejs/kit/issues/3419)). This was enabled by switching to the Undici `fetch` implementation ([#5117](https://github.com/sveltejs/kit/pull/5117))
- Static assets can now be symlinked in development environments ([#5089](https://github.com/sveltejs/kit/pull/5089))
- `server` and `prod` environment variables are now available as a corollary to `browser` and `dev` ([#5251](https://github.com/sveltejs/kit/pull/5251))

title: "What's new in Svelte: August 2022"
description: "Changes to SvelteKit's `load` before 1.0 plus support for Vite 3 and `vite.config.js`!"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
There's a lot to cover this month... big changes are coming to SvelteKit's design before 1.0 can be completed. If you haven't already, check out Rich's Discussion, [Fixing `load`, and tightening up SvelteKit's design before 1.0 #5748](https://github.com/sveltejs/kit/discussions/5748).
Also, [@dummdidumm](https://github.com/dummdidumm) (Simon H) [has joined Vercel to work on Svelte full-time](https://twitter.com/dummdidumm_/status/1549041206348222464) and [@tcc-sejohnson](https://github.com/tcc-sejohnson) has joined the group of SvelteKit maintainers! We're super excited to have additional maintainers now dedicated to working on Svelte and SvelteKit and have already been noticing their impact. July was the third largest month for SvelteKit changes since its inception!
Now onto the rest of the updates...
## What's new in SvelteKit
- Dynamically imported styles are now included during SSR ([#5138](https://github.com/sveltejs/kit/pull/5138))
- Improvements to routes and prop updates to prevent unnecessary rerendering ([#5654](https://github.com/sveltejs/kit/pull/5654), [#5671](https://github.com/sveltejs/kit/pull/5671))

- Custom Vite config locations are now supported ([#5705](https://github.com/sveltejs/kit/pull/5705))
- Private environment variables (aka "secrets") are now much more secure. Now if you accidentally import them to client-side code, you'll see an error ([#5663](https://github.com/sveltejs/kit/pull/5663), [Docs](https://kit.svelte.dev/docs/configuration#env))
- Vercel's v3 build output API is now being used in `adapter-vercel` ([#5514](https://github.com/sveltejs/kit/pull/5514))
- `vite-plugin-svelte` has reached 1.0 and now supports Vite 3. You'll notice new default ports for `dev` (port 5173) and `preview` (port 4173) ([#5005](https://github.com/sveltejs/kit/pull/5005), [vite-plugin-svelte CHANGELOG](https://github.com/sveltejs/vite-plugin-svelte/blob/main/packages/vite-plugin-svelte/CHANGELOG.md))

- `svelte-kit` CLI commands are now run using the `vite` command and `vite.config.js` is required. This will allow first-class support with other projects in the Vite ecosystem like Vitest and Storybook ([#5332](https://github.com/sveltejs/kit/pull/5332), [Docs](https://kit.svelte.dev/docs/project-structure#project-files-vite-config-js))
- `endpointExtensions` is now `moduleExtensions` and can be used to filter param matchers ([#5085](https://github.com/sveltejs/kit/pull/5085), [Docs](https://kit.svelte.dev/docs/configuration#moduleextensions))
- Node 16.9 is now the minimum version for SvelteKit ([#5395](https://github.com/sveltejs/kit/pull/5395))
- %-encoded filenames are now allowed. If you had a `%` in your route, you must now encode it with `%25` ([#5056](https://github.com/sveltejs/kit/pull/5056))
- Endpoint method names are now uppercased to match HTTP specifications ([#5513](https://github.com/sveltejs/kit/pull/5513), [Docs](https://kit.svelte.dev/docs/routing#endpoints))
- `writeStatic` has been removed to align with Vite's config ([#5618](https://github.com/sveltejs/kit/pull/5618))
- `transformPage` is now `transformPageChunk` ([#5657](https://github.com/sveltejs/kit/pull/5657), [Docs](https://kit.svelte.dev/docs/hooks#handle))
- The `prepare` script is no longer needed in `package.json` ([#5760](https://github.com/sveltejs/kit/pull/5760))
- `adapter-node` no longer does any compression while we wait for a [bug fix in the `compression` library](https://github.com/expressjs/compression/pull/183) ([#5560](https://github.com/sveltejs/kit/pull/5506))
For a full list of changes, check out kit's [CHANGELOG](https://github.com/sveltejs/kit/blob/master/packages/kit/CHANGELOG.md).

title: "What's new in Svelte: September 2022"
description: "Migrating to SvelteKit's new filesystem-based router"
author: Dani Sandoval
authorURL: https://dreamindani.com

Still looking for something to do this month? It's your last chance to get tickets to Svelte Summit, Stockholm! [Join us on Sept 8-9th](https://www.sveltesummit.com/) 🎉
With the redesign of SvelteKit's filesystem-based router merging early last month, there's lots to cover this month - from the [migration script](https://github.com/sveltejs/kit/discussions/5774) to a number of new blog posts, videos and tutorials.
But the new routing isn't the only new feature in SvelteKit...
## What's new in SvelteKit
- `Link` is now supported as an HTTP header and works out of the box with Cloudflare's [Automatic Early Hints](https://github.com/sveltejs/kit/issues/5455) (**1.0.0-next.405**, [PR](https://github.com/sveltejs/kit/pull/5735))
- `$env/static/*` are now virtual to prevent writing sensitive values to disk (**1.0.0-next.413**, [PR](https://github.com/sveltejs/kit/pull/5825))
- `$app/stores` can now be used from anywhere on the browser (**1.0.0-next.428**, [PR](https://github.com/sveltejs/kit/pull/6100))
- `config.kit.env.dir` is a new config that sets the directory to search for `.env` files (**1.0.0-next.430**, [PR](https://github.com/sveltejs/kit/pull/6175))
**Breaking changes:**
- The filesystem-based router and `load` API improves the way routes are managed. **Before installing version `@sveltejs/kit@1.0.0-next.406` or later, [follow this migration guide](https://github.com/sveltejs/kit/discussions/5774)** ([PR](https://github.com/sveltejs/kit/pull/5778), [Issue](https://github.com/sveltejs/kit/discussions/5748))
- `event.session` has been removed from `load` along with the `session` store and `getSession`. Use `event.locals` instead (**1.0.0-next.415**, [PR](https://github.com/sveltejs/kit/pull/5946))
- Named layouts have been removed in favor of `(groups)` (**1.0.0-next.432**, [Docs](https://kit.svelte.dev/docs/advanced-routing#advanced-layouts), [PR & Migration Instructions](https://github.com/sveltejs/kit/pull/6174))
- `event.clientAddress` is now `event.getClientAddress()` (**1.0.0-next.438**, [PR](https://github.com/sveltejs/kit/pull/6237))
- `$app/env` has been renamed to `$app/environment`, to disambiguate with `$env/...` (**1.0.0-next.445**, [PR](https://github.com/sveltejs/kit/pull/6334))
For a full list of changes, check out kit's [CHANGELOG](https://github.com/sveltejs/kit/blob/master/packages/kit/CHANGELOG.md).
**Updates to language tools**
- TypeScript doesn't resolve imports to SvelteKit's $types very well, the latest version of Svelte's language tools makes it better (**105.21.0**, [#1592](https://github.com/sveltejs/language-tools/pull/1592))

title: "What's new in Svelte: November 2022"
description: "Better forms, routes and inline styles across SvelteKit and Svelte"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
It's been a busy October for the Svelte community. `use:enhance` and Advanced Routes got some great improvements in SvelteKit while the Svelte compiler released a minor version to improve the day-to-day dev experience.
There's also a _huge_ showcase to cover... so let's jump in!
## What's new in SvelteKit
- The new `update` method for `use:enhance` lets you easily get back the default form behavior while augmenting it with your own logic ([docs](https://kit.svelte.dev/docs/form-actions#progressive-enhancement-use-enhance), [#7083](https://github.com/sveltejs/kit/pull/7083) and [#7326](https://github.com/sveltejs/kit/pull/7326))
- `[[optional]]` parameters are now available for routing ([docs](https://kit.svelte.dev/docs/advanced-routing#optional-parameters), [#7051](https://github.com/sveltejs/kit/pull/7051))
- `goto` now has `invalidateAll` to (re-)run all `load` functions belonging to the new active page ([docs](https://kit.svelte.dev/docs/modules#$app-navigation-goto), [#7407](https://github.com/sveltejs/kit/pull/7407))
- `config.kit.paths.base` is now used in adapters looking for static assets - fixing 404 issues across `adapter-netlify`, `adapter-vercel`, `adapter-cloudflare`, and `adapter-cloudflare-workers` ([#4448](https://github.com/sveltejs/kit/pull/4448))
**Breaking changes:**
- Errors will now be thrown when routes conflict ([#7051](https://github.com/sveltejs/kit/pull/7051))
- The global `fetch` override has been removed when prerendering ([#7318](https://github.com/sveltejs/kit/pull/7318))
- Route IDs have been prefixed with `/` ([#7338](https://github.com/sveltejs/kit/pull/7338))
## Svelte changes
- New accessibility warnings, `a11y-click-events-have-key-events` and `a11y-no-noninteractive-tabindex`, will now warn when your components lack required key events or tabindex. While `a11y-role-has-required-aria-props` will no longer warn when elements match their semantic role (**3.51.0**)
- `--style-props` are now supported on `<svelte:component>` and `<svg>` (**3.51.0**, Component Example: [Before](https://svelte.dev/repl/48984f20503f4959b70f24f4130d164b?version=3.47.0) and [After](https://svelte.dev/repl/48984f20503f4959b70f24f4130d164b?version=3.51.0), SVG Example: [Before](https://svelte.dev/repl/b7a3f94255914044b35462234ccaea43?version=3.50.0) and [After](https://svelte.dev/repl/b7a3f94255914044b35462234ccaea43?version=3.51.0))
- "nullish" values for component event handlers are now supported (**3.51.0**, [Example](https://svelte.dev/repl/9228022922af4c76af68ce42349ccbf9?version=3.51.0))
- Scoped styles can now be applied to `<svelte:element>` (**3.51.0**, [Example](https://svelte.dev/repl/23d982fc6f4f4f06a6aa227860fa2d84?version=3.51.0))
- You can now use `important` in inline style tags: `style:foo|important` (**3.52.0**, [#7365](https://github.com/sveltejs/svelte/issues/7365))
- A warning will now be thrown when using `<a target="_blank">` without `rel="noreferrer"` (**3.52.0**, [#6188](https://github.com/sveltejs/svelte/issues/6188))
Tom Smykowski also released a great summary of [all the changes in 3.52.0](https://tomaszs2.medium.com/svelte-3-52-0-improves-dev-experience-45f8c460bb96)!

title: "What's new in Svelte: December 2022"
description: "Rounding the corner to SvelteKit 1.0"
author: Dani Sandoval
authorURL: https://dreamindani.com
---
SvelteKit 1.0 is just around the corner! With [99% of the milestone issues completed](https://github.com/sveltejs/kit/milestone/2), there's a lot of new changes from the last month to cover...
Let's get to it!
## What's new in SvelteKit
- Use the `willUnload` property to find out if the navigation will result the app being unloaded (full page reload/closing/leaving to another page). ([#6813](https://github.com/sveltejs/kit/pull/6813))
- `__data.json` requests now allows for caching while ensuring we cache matching responses for all invalidation scenarios ([#7532](https://github.com/sveltejs/kit/pull/7532))
- Linking to `<a name="hash">` tags is now supported ([#7596](https://github.com/sveltejs/kit/pull/7596))
- Throwing redirects in the `handle` hook is now supported ([#7612](https://github.com/sveltejs/kit/pull/7612))
- A fallback component will now be added automatically for layouts without one ([#7619](https://github.com/sveltejs/kit/pull/7619))
- The new `preload` function within the `resolve` hook determines what files should be added to the <head> tag to preload it ([Docs](https://kit.svelte.dev/docs/hooks#server-hooks-handle), [#4963](https://github.com/sveltejs/kit/pull/4963), [#7704](https://github.com/sveltejs/kit/pull/7704))
- `version` is now available via `$app/environment` ([#7689](https://github.com/sveltejs/kit/pull/7689), [#7694](https://github.com/sveltejs/kit/pull/7694))
- `handleError` can now return a promise ([#7780](https://github.com/sveltejs/kit/pull/7780))
**Breaking changes:**
- `routeId` is now `route.id` ([#7450](https://github.com/sveltejs/kit/pull/7450))
- 'load' has been renamed to 'enter' and 'unload' to 'leave' in the `beforeNavigate` and `afterNavigate` methods. `beforeNavigate` is now called once with type 'unload' on external navigation and will no longer run during redirects ([#7502](https://github.com/sveltejs/kit/pull/7502), [#7529](https://github.com/sveltejs/kit/pull/7529), [#7588](https://github.com/sveltejs/kit/pull/7588))
- The `redirect` helper will now only allow status codes between 300-308 for redirects and only `error` status codes between 400-599 are allowed ([#7767](https://github.com/sveltejs/kit/pull/7767)) ([#7615](https://github.com/sveltejs/kit/pull/7615), [#7767](https://github.com/sveltejs/kit/pull/7767))
- Special characters will now be encoded with hex/unicode escape sequences in route directory names ([#7644](https://github.com/sveltejs/kit/pull/7644))
- devalue is now used to (de)serialize action data - this is only a breaking change for everyone who fetches the actions directly and doesn't go through `use:enhance` ([#7494](https://github.com/sveltejs/kit/pull/7494))
- `trailingSlash` is now a page option, rather than configuration ([#7719](https://github.com/sveltejs/kit/pull/7719))
- The client-side router now ignores links outside `%sveltekit.body%` ([#7766](https://github.com/sveltejs/kit/pull/7766))
- `prerendering` is now named `building`, and `config.kit.prerender.enabled` has been removed ([#7762](https://github.com/sveltejs/kit/pull/7762))
- `getStaticDirectory()` has been removed from the builder API ([#7809](https://github.com/sveltejs/kit/pull/7809))
- The `format` option has been removed from `generateManifest(...)` ([#7820](https://github.com/sveltejs/kit/pull/7820))
- `data-sveltekit-prefetch` has been replaced with `-preload-code` and `-preload-data`, `prefetch` is now `preloadData` and `prefetchRoutes` is now `preloadCode` ([#7776](https://github.com/sveltejs/kit/pull/7776), [#7776](https://github.com/sveltejs/kit/pull/7776))
- `SubmitFunction` has been moved from `$app/forms` into `@sveltejs/kit` ([#7003](https://github.com/sveltejs/kit/pull/7003))
## New in Svelte
- The css compiler options of `css: false` and `css: true` have been replaced with `'external' | 'injected' | 'none'` settings to speed up compilation for `ssr` builds and improve clarity (**3.53.0**)
For all the changes to the Svelte compiler, including unreleased changes, check out the [CHANGELOG](https://github.com/sveltejs/svelte/blob/master/CHANGELOG.md).

title: Announcing SvelteKit 1.0
description: Web development, streamlined
author: The Svelte team
---
After two years in development, [SvelteKit](https://kit.svelte.dev) has finally reached 1.0. As of today, its the recommended way to build Svelte apps of all shapes and sizes.
Were so excited to share this release with you. Its the culmination of thousands of hours of work, both from the Svelte core team and the wider community, and we think its the most enjoyable way to build production-grade websites, whether youre a solo developer working on a small project or part of a large team.
To get started, run `npm create svelte@latest`, and visit the [docs](https://kit.svelte.dev/docs) and (experimental!) [interactive tutorial](https://learn.svelte.dev).

## What is SvelteKit?
SvelteKit is a framework for building web applications on top of [Svelte](https://svelte.dev), a UI component framework [that](https://insights.stackoverflow.com/survey/2021#section-most-loved-dreaded-and-wanted-web-frameworks) [developers](https://2021.stateofjs.com/en-US/libraries/front-end-frameworks/) [love](https://twitter.com/Rich_Harris/status/1589675637195042817) for its performance and ease of use.
If youve used component frameworks like Svelte, youll know that they make it much easier to build user interfaces than working with the DOM directly. But they leave a lot of questions unanswered:
- How do I structure my source code?
- How do I add server-side rendering?
- How do I add routing that works on the server and in the browser?
- How do I make client-side routing accessible?
- How do I fetch data?
- How do I mutate data?
- How do I handle errors?
- How do I optimise my production build?
- How do I handle environment variables sensibly and securely?
- How do I add CSP headers and CSRF protection?
- How do I add a service worker that knows what to cache?
- How do I prepare my application for deployment?
An application framework is designed to answer these questions. SvelteKit does so with a design informed by the real world needs of an army of beta testers (many of whom have been running SvelteKit in production for some time — we salute your courage and thank you for the invaluable feedback) and the best ideas from other application frameworks including [Next.js](https://nextjs.org/) and [Remix](https://remix.run/).
## How is it different?
Web developers today are spoiled for choice. Aside from the aforementioned frameworks, there are options like [Astro](https://astro.build/), battle-tested server frameworks like [Rails](https://rubyonrails.org/) and [Laravel](https://laravel.com/), and a million static site generators. These are all wonderful tools, and you should feel good about choosing them.
SvelteKit does things a little differently, however:
**Unlike traditional multi-page app or MPA frameworks,** it defaults to client-side navigation after the initial server-rendered page load. This enables faster page transitions, state that persists between pages (such as a sidebars scroll position), and less data usage. It also avoids re-running third party scripts like analytics on every single page load.
**Unlike traditional server frameworks,** it allows you to use one language, instead of effectively having two tightly-coupled apps (one to generate HTML, one to handle client-side interaction). Because SvelteKit runs wherever JavaScript runs, you can deploy your app as a traditional Node server, or using serverless functions — including at the edge.
**Unlike static site generators,** you can build apps with personalised or dynamic data — without the performance-killing, layout-shifting effects of fetching it from the browser after the page loads.
With SvelteKit, you have flexibility. Many frameworks assume theres one correct way to build an app, but reality is more nuanced. Its not true, for example, that prerendering static pages is just a poor mans `cache-control` — it also lets you do build-time validation or render data from the filesystem that your edge functions cant access, and acts as a hedge against flaky databases. Its not true that everything needs server-side rendering — its the right default if you want robust, performant apps with good SEO, but there are countless exceptions.
In a SvelteKit app, you can make these choices with as much granularity as you need — for example the page youre looking at is prerendered, but the [REPL](/repl) is rendered with dynamic data. Switching between the two is a single line of code. We call apps built with this approach [transitional apps](https://www.youtube.com/watch?v=860d8usGC0o).
## What can I use with SvelteKit?
Because SvelteKit uses [Vite](https://vitejs.dev/), the lightning-fast build tool, it has out-of-the-box support for hot module reloading, TypeScript, and many other things that developers rely on. You can install plugins from the vast Vite and Rollup ecosystems to add support for other tools.
When creating a SvelteKit project youll be asked if you want to add [TypeScript](https://www.typescriptlang.org/), [ESLint](https://eslint.org/), [Prettier](https://prettier.io/), [Playwright](https://playwright.dev/) (for end-to-end browser tests) and [Vitest](https://vitest.dev/) (for unit tests). Integration guides already exist for many popular projects — [Tailwind](https://tailwindcss.com/docs/guides/sveltekit) and [Supabase](https://supabase.com/docs/guides/getting-started/tutorials/with-sveltekit), for example. You can use [Storybook](https://github.com/storybookjs/storybook/blob/next/code/frameworks/sveltekit/README.md) and [Histoire](https://histoire.dev/guide/svelte3/getting-started.html) for your component stories. The community-maintained [svelte-add](https://github.com/svelte-add/svelte-add) lets you add a growing list of other integrations with a single command.
And of course you have access to everything [npm](https://npmjs.com/) has to offer. (Note that some packages require Node.js, and so can only be used when deployed to Node-based platforms.)
## Where can I deploy my apps?
Anywhere! The SvelteKit CLI needs Node.js installed locally, but the framework itself has no dependencies on any platform. This means you can deploy it wherever JavaScript runs.
This is made possible by [adapters](https://kit.svelte.dev/docs/adapters). The default adapter, [adapter-auto](https://github.com/sveltejs/kit/tree/master/packages/adapter-auto), provides zero-config support for Vercel, Netlify, Cloudflare Pages and Azure Static Web Apps, with more platforms coming in the future. Community-provided adapters add support for Deno, Bun, Firebase, App Engine, AWS Lambda and many others.
You can also deploy your app as a Node.js server using [adapter-node](https://github.com/sveltejs/kit/tree/master/packages/adapter-node).
If your entire app is suitable for prerendering, or is a single-page app (SPA), you can use [adapter-static](https://github.com/sveltejs/kit/tree/master/packages/adapter-static) — which turns SvelteKit into a static site generator — with any web server including [GitHub Pages](https://pages.github.com/).
## Acknowledgements
This release was made possible by the hard work of a great many people. First and foremost, wed like to thank the Svelte community, whose insightful feedback and myriad contributions large and small have shaped this project into something were truly proud to share with the wider community of web developers.
Were also indebted to [Svelte Society](https://sveltesociety.dev/) and the community ambassadors, who, through initiatives like [Svelte Summit](https://www.sveltesummit.com/) and [Svelte Sirens](https://sveltesirens.dev/), have created a lively and welcoming space for Svelte developers, both online and IRL.
There are too many content creators to name without leaving people left out, but to everyone who has released courses and produced educational content around SvelteKit: thank you.
Back in early 2021, when we adopted Vite, we were the first major application framework to do so. At the time it was a risky bet, but were thrilled with how that bet paid off. Vite has grown to be an unstoppable force in the JavaScript world, and the Vite team have been brilliant and gracious partners.
Weve had terrific support from teams at [Vercel](https://vercel.com), [Netlify](https://netlify.app/) and [Cloudflare](https://www.cloudflare.com/) to make zero-config deployments for those platforms possible.
Our friends at [StackBlitz](https://stackblitz.com/) worked feverishly to make [learn.svelte.dev](https://learn.svelte.dev), our first-of-its-kind [WebContainer](https://blog.stackblitz.com/posts/introducing-webcontainers/)-powered interactive tutorial, a reality.
Finally, none of this could have happened without the projects financial supporters. This includes hundreds of backers on [Open Collective](https://opencollective.com/svelte), and Vercel, which employs two core developers ([Rich](https://twitter.com/Rich_Harris/) and [Simon](https://twitter.com/dummdidumm_/)) to work on Svelte full time and supports the project in many other ways, such as [Stephs](https://twitter.com/steph_dietz_) [Beginner SvelteKit](https://vercel.com/docs/beginner-sveltekit) course.
## Migrating
If you have an app built with pre-release versions of SvelteKit, we recommend upgrading to the final pre-release version — `@sveltejs/kit@1.0.0-next.588` — before upgrading to 1.0, as the stable release removes errors and warnings that were used for migrating between pre-release versions. We also recommend consulting [this migration guide](https://github.com/sveltejs/kit/discussions/5774), especially if youre currently on an older version than 1.0.0-next-406.
## Whats next?
SvelteKit 1.0 is the beginning, not the end. Its ready for production use today, but were just getting started. Our roadmap includes built-in i18n support, incremental static regeneration, granular control over deployment region and runtime, image optimisation, and many other improvements. Next year well also start work on Svelte 4 — more on that later.
But dont let us have the final word. Svelte is a community project, and many of our best ideas arent really ours at all — theyre yours. Subscribe to Svelte Society on [Twitter](https://twitter.com/SvelteSociety) and [YouTube](https://youtube.com/sveltesociety) to stay up to date, and join us in our [Discord server](https://svelte.dev/chat) and on [GitHub](https://github.com/sveltejs) to contribute back.
We cant wait to see what you build.

title: "What's new in Svelte: February 2023"
description: 'Minor versions and major satisfaction'
author: Dani Sandoval
authorURL: https://dreamindani.com
---
Since last month, we've seen a couple of minor versions across Svelte and SvelteKit, a bunch of educational content to support the 1.0 release, as well as the [State of JS survey](https://stateofjs.com) results...
Svelte, once again, increased in satisfaction and interest, so thanks to everyone who voted!
Let's dive into the updates...
## What's new in SvelteKit
Work in the Svelte ecosystem this month has been focused on SvelteKit bug fixes and addressing feedback from the 1.0 launch. One of the more awaited [bug fixes to SvelteKit's base path support](https://github.com/sveltejs/kit/issues/2958) landed, which means that you can now create SvelteKit projects on remote development environments. There have been several [new releases](https://github.com/sveltejs/kit/blob/master/packages/kit/CHANGELOG.md) with these fixes as well as a handful of new features such as:
- The submitter's value will now be included automatically when progressively enhancing <form method="get"> (**1.0.3**, [#8273](https://github.com/sveltejs/kit/pull/8273))
- Added an error in dev mode if global fetch is used with relative URL (**1.0.8**, [#8370](https://github.com/sveltejs/kit/pull/8370))
- A warning will now indicated that hydration may break if comments are removed from HTML (**1.0.11**, [#8423](https://github.com/sveltejs/kit/pull/8423))
- A warning will occur when of page options are used in `.svelte` files or a missing `<slot />` in layout is detected (**1.1.0**, [#8475](https://github.com/sveltejs/kit/pull/8475))
- The new `text(...)` helper makes it easy to generate text responses (**1.2.0**, [#8371](https://github.com/sveltejs/kit/pull/8371))
- The public env can now be accessed within app.html (**1.2.0**, [Docs](https://kit.svelte.dev/docs/project-structure#project-files-src), [#8449](https://github.com/sveltejs/kit/pull/8449))
- An error will now be thrown if cookie exceeds size limit (**1.2.1**, [#8591](https://github.com/sveltejs/kit/pull/8591))
- The generated `tsconfig` can now be modified (**1.3.0**, [#8606](https://github.com/sveltejs/kit/pull/8606))
## What's new in Svelte and Language Tools
- Added support for `html.customData` from the VS Code HTML language service (**extensions-107.0.0**, [#1824](https://github.com/sveltejs/language-tools/pull/1824))
- Autocompletion for stores that need to be imported ([#1823](https://github.com/sveltejs/language-tools/pull/1823)) and object/class member snippets ([#1817](https://github.com/sveltejs/language-tools/pull/1817)) has been added to the Svelte extension (**extensions-107.0.0**)
- Improve detection of promises that are also functions (**Svelte 3.55.1**, [#8162](https://github.com/sveltejs/svelte/pull/8162))
