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.

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.

To illustrate, let's look at a very simple component implemented in React, Vue and Svelte. First, the Svelte version: - -

- -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 ( -
- - - -

{a} + {b} = {a + b}

- ); -}; -``` - -Here's an equivalent component in Vue: - -```html - - - -``` - - - -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 `
`, 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 `
