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: Daniel Sandoval
|
||||
authorURL: https://desandoval.net
|
||||
---
|
||||
|
||||
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))

Sometimes we don't know in advance what kind of DOM element to render. `<svelte:element>` comes in handy here. Instead of a sequence of `if` blocks...
|
||||
|
||||
```html
|
||||
{#if selected === 'h1'}
|
||||
<h1>I'm a h1 tag</h1>
|
||||
{:else if selected === 'h3'}
|
||||
<h3>I'm a h3 tag</h3>
|
||||
{:else if selected === 'p'}
|
||||
<p>I'm a p tag</p>
|
||||
{/if}
|
||||
```
|
||||
|
||||
...we can have a single dynamic component:
|
||||
|
||||
```html
|
||||
<svelte:element this={selected}>I'm a {selected} tag</svelte:element>
|
||||
```
|
||||
|
||||

* Actions can return an object containing the two properties defined in this interface. Both are optional.
|

* - update: An action can have a parameter. This method will be called whenever that parameter changes,
|

* immediately after Svelte has applied updates to the markup.
|
||||
* - destroy: Method that is called after the element is unmounted
|
||||
*
|
||||
* Example usage:
|

* ```ts
|

* export function myAction(node: HTMLElement, parameter: Parameter): ActionReturn<Parameter> {
|
||||
* // ...
|
||||
* return {
