What's new in Svelte: September 2022

Migrating to SvelteKit's new filesystem-based router

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 🎉

With the redesign of SvelteKit's filesystem-based router merging early last month, there's lots to cover this month - from the migration script 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 (1.0.0-next.405, PR)

• $env/static/* are now virtual to prevent writing sensitive values to disk (1.0.0-next.413, PR)

• $app/stores can now be used from anywhere on the browser (1.0.0-next.428, PR)

• config.kit.env.dir is a new config that sets the directory to search for .env files (1.0.0-next.430, PR)

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 (PR, Issue)

• event.session has been removed from load along with the session store and getSession. Use event.locals instead (1.0.0-next.415, PR)

• Named layouts have been removed in favor of (groups) (1.0.0-next.432, Docs, PR & Migration Instructions)

• event.clientAddress is now event.getClientAddress() (1.0.0-next.438, PR)

• $app/env has been renamed to $app/environment, to disambiguate with $env/... (1.0.0-next.445, PR)

For a full list of changes, check out kit's CHANGELOG.

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)
