We recently undertook an effort to improve the reliability of Rust Workers, which involved implementing panic=unwind and abort recovery in Wasm Bindgen using WebAssembly Exception Handling. Excited to be able to share this work! blog.cloudflare.com/making-rust-...

PSA: If you want to use standard CSS Modules before they ships in Safari and Firefox, I built a Rollup plugin to support them: www.npmjs.com/package/roll... Converting CSS Modules to JS this way also support bundling before @sheet (which lets you put multiple stylsheets in one CSS file) lands.

Blink: Intent to Prototype: Source phase imports

It blows my mind when JS packages publish for every commit and end up with thousands of versions on npm. For example Primer React (www.npmjs.com/package/@pri...) publishes ~20 - 30 times a day via commit-based CI. Good dev pattern, or misuse of npm?
