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.

It's been great to work on prototyping this! I'm really excited by typescript-go and looking forward to getting this released as soon as we can. The future is fast ⚡️

oxlint + tsgolint = no slow down! no-floating-promises completes 4.4k files in 3.2 seconds, in the vscode repo. typescript-go is the future, all credits to the ts-go team! We just glued everything together 😀 github.com/microsoft/ty...

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 👏

✨ Node.js: Now with Rolldown? Yes - to some degree! @rolldown.rs is planned to power the future API documentation generator of @nodejs.org. More info in the linked PR! github.com/nodejs/api-d...

👀 Keep an eye out!

I am permitted to host tsgolint in Oxc and explore type aware linting! I am super excited! We reduced the original scope of tsgolint to be a backend for oxlint, taking the best out of both worlds! github.com/oxc-project/...

Something happened today at VueConf China! github.com/vuejs/core/r...

Introduction 𝗢𝘅𝗟𝗶𝗻𝘁 𝗙𝗼𝗿𝗺𝗮𝘁𝘁𝗲𝗿 𝗜𝗻𝘀𝗽𝗲𝗰𝘁𝗼𝗿: An interactive tool for inspecting oxlint formatter (@boshen.github.io) in the browser: - 🔍 Glob patterns search. - 🌈 Code highlight. - 📦 Static Build. - 💡 Rule detail. - 🚀 Launch Editor. Try it with: `npx oxlint-fi` Github: github.com/yuyinws/oxli...

Oxlint is 1.0!

Vue Equipment: The missing library for Nuxt and Vue. The frontend toolkit we couldn’t find — so we built it. And it's now yours → vue.equipment

Another real world Rolldown-Vite performance win: @sanity.io studio’s build time went from: 21.9s to 5.1s (4.29x, w/o React Compiler) 49.6s to 20.0s (2.48x, w/ React Compiler)

✋ [email protected] is out! - Browser Target Changed to Baseline Widely Available - Node 18 support dropped. Vite is now distributed as ESM only Plus fixes and deprecated feats removals, preparing for rolldown. Help us test the beta and report back 🙏 github.com/vitejs/vite/...

Don't miss what happened in the last weeks - tsdown is now part of VoidZero - Vite Devtools Sneak Peek - oxc-minify in Rolldown - rolldown-vite improvements - ViteConf Speaker Overview - Upcoming meetup in San Francisco - Goxc and Godown More in this thread 👇

I've been so surprised! Just only by tweaking the npm alias in my day-job project, We were able to build with rolldown-vite. I didn't touch vite.config at all. 🚀 Build performance has been between 4.4x and 8x faster than the existing vite version!

We are planning to port this to Rust as well in the future. Meaning you'll be able to build both your JS bundle and bundled dts files in one go with @rolldown.rs when you use isolated declarations!
