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)

  • Concurrency mode in SvelteKit will now prerender pages in parallel (#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)

  • A new config option adds the ability to disable service worker registration to do your own custom registration (#2988)

  • SSR route-splitting is here - breaking monolithic builds into smaller pieces for improved startup and routing performance (#2931)

  • request.origin/path/query is now request.url - simplifying the config and page load functions (#3126)

  • After the update to Vite 2.7, SvelteKit users are reporting significant performance improvements 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)

Other new bits from svelte/*

  • Svelte 3.44.3 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)

  • The Svelte REPL got a nice upgrade as well - letting you delete saved REPLs. Try it out by logging in at svelte.dev/apps


Community Showcase

Apps & Sites

  • Discover Twitter Spaces is a tool that helps you find the Twitter Spaces

  • Modern Fluid Typography Editor helps create beautiful fluid typography using CSS clamp

  • Unnwhiteboard is a job board for companies (or teams) that don't do "whiteboard" interviews

  • Secret Santa is a gift giving coordination app developed with easiness in mind

  • Version 0.2 of Tangent, a Svelte-based note writing app, is now in beta

  • Intl Explorer is a tool for viewing output for all possible formatters for Intl

A lot of work this month has gone into migrating the Svelte main website and Svelte REPL to live in the https://github.com/sveltejs/sites repository - including a brand new homepage for svelte.dev. Thanks to all the contributors who made this possible!
