Svelte is migrating from TypeScript to JSDoc

• Svelte

  632 76,402 9.9 JavaScript

  Cybernetically enhanced web apps

  

Svelte will still provide type definitions. We're working on Svelte 4 currently and are taking the opportunity to make a few small breaking changes to the type definitions for improved TypeScript support: https://github.com/sveltejs/svelte/blob/version-4/CHANGELOG....

We'll cut a preview release soon and would love help testing and feedback from folks that have given it a try.

• closure-compiler

  14 7,247 9.6 Java

  A JavaScript checker and optimizer.

  

10 years ago I have used Closure compiler from Google, https://github.com/google/closure-compiler/wiki/Annotating-T... , as a type checker. We had to use for production a different minimizer, not the closure compiler, but it was extremely useful to check for types and JSDoc-style annotations were very readable with minimal distraction.

Flow for JS from Facebook also supports types-as-comments, https://flow.org/en/docs/types/comments/ , but those are rather ugly as one has to intermix them with JS rather than using separated comment block on top.

• proposal-type-annotations

  101 4,086 4.7 JavaScript

  ECMAScript proposal for type syntax that is erased - Stage 1

  

This is great but -if I dare - wouldn't it be time to allow js to have type annotations [1] ? As in python, treat it as comments for now but with real syntax and let interesting dialects emerge from the consensus ? I like jsdoc but the syntax is urgh.

• abstract-state-router

  1 295 6.3 JavaScript

  Like ui-router, but without all the Angular. The best way to structure a single-page webapp.

I'm still using https://github.com/TehShrike/abstract-state-router which I wrote years ago after thinking "ui-router is great, but I need a version that can keep using no matter what component library I want to use in the future"
