Announcing Oxlint Type-Aware Linting Alpha 🎁 Just a few months after our technical preview, type-aware linting reaches the alpha milestone! ✨ Type-aware rules can now be configured 🙈 Inline comments to disable rules work for type-aware rules too ✔ Auto fixes for type-aware rules are now available

A new milestone! @vitest.dev hit 20 million mark 🎉 Took us 4 years since the first closed 0.0.0 release on December 3d, 2021 😄

Announcing Oxfmt Alpha! 🚀 We’re excited to announce the alpha release of Oxfmt, our Rust-powered formatter. We designed Oxfmt to be easily adoptable, especially for existing Prettier users More below and in our announcement post voidzero.dev/posts/announ...

Instead of providing your tsconfig manually in @rolldown.rs, you can now enable @vite.dev like automatic resolution. ◇ Finds the nearest tsconfig.json ◇ Respected by both, resolver and transformer ◇ tsconfig references will be searched as well (given certain criteria are fulfilled)

I'm using tsgo + oxlint + oxfmt for the first time. It's all *so fast*. Small project (~1k loc, ~10 files), but type checking in 90ms, building in 60ms, linting in 70ms, and formatting in 80ms is fantastic. 🚀 The future of web dev tooling is bright. Nice work @typescriptlang.org and @voidzero.dev!

Vitest 4.0.11 adds an experimental `fsModuleCache` flag to cache module transforms between reruns. Learn more: vitest.dev/config/exper... This is an opt-in feature, please let us know how it works for you! And example of a single test file that imports a lot of files (~1500). Almost a 50% boost!
