Working on a page that you can search vite plugins. I'm planning to allow plugins to add metadata for that page via a field in package.json. I wonder if it's a good idea to use a generic name like `compatiblePackages`. registry.vite.dev/guide/extend...

we're making typescript-go faster for tsgolint! optimizing the tsconfig file registry has yielded a 52x perf improvement when benchmarking against affine and we've got more on the way: 154.61s user 21.70s system 812% cpu 21.711 total 0.71s user 0.84s system 369% cpu 0.417 total

In the latest @rolldown.rs powered @vite.dev version, we've enabled the rust-based resolver plugin by default! This will lead to even faster builds in case you don't use the experimental native plugins yet. Wanna try out more native core plugins? Then enable them and make sure to use rolldown-vite

`oxlint --type-aware`. Mic drop. It's incomplete and have numerous problems, including a noticeable performance issue. BUT, you can finally see your floating promises quickly! Example PR: github.com/rolldown/rol... Problems: t.co/K7ZVnPjOPL

A phishing attack is going on against maintainers on @npmjs.bsky.social, be aware! - email is spoofed from npmjs.org (which doesn’t use DMARC but redirects to npmjs.com) - login link points to npnjs(dot)com (clear giveaway)

Oxlint is making a huge step forward! Two new updates: JS custom rules, with ESLint compatible API are on the way. The first prototype gives a good speedup already! 🔥 Type-aware rules. Full coverage no-floating-promise through tsgolint, integrated like the other oxlint rules and extremely fast.

Wow! @sapphi.red just made @rolldown.rs Vite's startup time 2x quicker. How? By dealing with PIFEs and optimizing for the v8 engine, also coming to Oxc 👀 Everyone knows IIFEs but PIFEs? 😁 Really impressed by such deep knowledge 👏
