Type safety without writing the types yourself? This is now possible for all methods and variables with special meaning to SvelteKit!

This all started with @shuding_ sharing his work of auto-typings for Next.js. It got us inspired to see what this could look like for SvelteKit. I prototyped this and we immediately felt an improvement in productivity and DX.

While this is super convenient, this isn't just about that. It's also about correctness: I forgot or got some types mixed up more than once - the computer never will.

This is in line with Svelte's major insight that by writing code in a declarative way we can get the machine to do the bulk of the work for us, correctly and efficiently.

As usual, you and your team's work is incredible and appreciated!

Hyped!!! I guess that we have some homework to do over the weekend now 😅 +page.gql 😉

One of the things I love about @nuxt_js 3 💚

This is amazing! Great work 🎉 Would be perfect to have typescript syntax working on template as well for full type-safety everywhere in Svelte. Fingers crossed!

wait wait wait wait wait. How in the world does that export validation work 👀👀

It's part of the typescript plugin. It looks at the TS AST to check the top level exports and adds a custom error message if there's an invalid one
