Folks... this is a BIG DEAL. Things to know: 1. This is NOT "adding RxJS to the browser". There's a limited but solid set of functionality here. Not operator hell. 2. Adding observables to the platform means that many, many frameworks and libraries can leverage them instead of

SWC Added few small updates to woodpile: - adds `visitWithPath` , passes parent node types paths array to the callback - initial typescript definition allows to list all visit_* callbacks for the node types. npmjs.com/package/woodpi…

This is the first time I tried to use node.js's built in test runner, not a bad out of the box experience. I'd use other runners still for the complicated setups, but for the small things this would be useful. Not able to use Wallaby Team is one bad thing.

Having a reliable, isolated repro to bug report is one of the greatest way to help OSS maintainer for the OSS you use / like. Also, it'll help you as well as maintainers are likely can pick up the issue easier / faster.

Wrapping up my journey at Vercel and trying to go back to writing some more Typescript-y things. Still love Rust and hope to get back to some SWC work too.

Published a new version of woodpile (npmjs.com/package/woodpi…), SWC ast visitor in javascript. Fixed ast mutation, now `visit` returns mutated ast as js object.

Dust off swc-plugin-coverage-instrument (npmjs.com/package/swc-pl…), published a new version. This pkg prpvides instanbuljs-compatible coverage with SWC . The latest version have a new `unstableExclude` option to allow glob pattern to exclude certain file from instrumentation.

👏🏻 to Rspack team for the work to support seamless webpack migration + performance boost. Launched dev beta for the internal app with rapack 1.1 and HMR gots more than 2x faster at minimum. (If anyone asks why no Turbopack, this isn't next.js app)

Highly recommend Rspack if your codes are based on legacy webpack and would like to migrate seamlessly. Completed my work's replacement - prod ~1000% faster, HMR avg > 300% and up to 1000%. The bigger thing is we had 0 regressions, configuration migration was seamless.

Rstest is one the few (or only?) test framework integrates swc's istanbul coverage instrumentation plugin instead of re-transpiling with babel+istanbul.

Rspack has tons of complex tests. We just migrated from Jest to Rstest and saw about a 30% speed boost. ⚡️ If you’ve been thinking about trying Rstest, now might be a good time to give it a shot.
