Svelte

Remote Functions are coming to SvelteKit.

They're defined in `.remote.ts` files, come in four flavors (`query` / `form` / `command` / `prerender`) and support any validation library adhering to the Standard Schema protocol.

Benefits: end-to-end type-safety across frontend and backend, progressively enhanced forms that work with JavaScript disabled, and a slew of modern async request caching and invalidation patterns (single-flight mutations, partial pre-rendering, optimistic updates) built right in.

Svelte is adding support for the `await` keyword directly inside of the top-level `<script>`, `$derived()` expressions, and component markup.

HUGE unlock for making asynchronous reactive programming accessible for the masses.

This is all building upon another huge effort to `async`-ify all the Svelte primitives, which you can read all about here:

For the React / Next.js devs – this is like all the best parts of tRPC, TanStack Query, React Server Functions and old Remix – but now built right into the full-stack framework.

Not to mention all the client-side signal-based fine-grained reactivity goodies that every other framework has gotten to enjoy (and that you are sorely missing out on!).

Amusement, wonder, and uncertainty. now [redacted], prev @neynar ✴︎ libred.org

Yes, React’s and Solid’s. Svelte’s approach much cleaner — as usual :)

You’re referring to React Server Functions?

The Svelte team is learning from that and taking things in a different direction. Notably, not co-locating server code in the same file as client-side code.

Hell has frozen. The community was quite contra server functions but I guess that's becoming a standard now
