Today, VoidZero joins Cloudflare. Vite remains MIT, vendor-neutral, and stewarded by the same wider team. The same goes for Vitest, Rolldown, and Oxc. Cloudflare is also committing $1M to an OSS fund to support independent development in the Vite ecosystem.

VoidZero is joining Cloudflare. Our mission stays the same: to make JavaScript developers more productive than ever before. Vite, Vitest, Rolldown, Oxc, and Vite+ remain MIT-licensed. Evan and the VoidZero team will continue leading them.

🚀 tsdown v0.22 is out, now powered by Rolldown 1.0.0! What’s new: ✦ Upgraded to Rolldown v1.0.0 ✦ Reduced install size by 1.33 MB ✦ Auto-detects the `bin` field ✦ Dropped support for Node.js 20, 21, and 23 ✦ `dts` is now inferred from `compilerOptions.declaration` github.com/rolldown/tsd...

I was debugging some chunking regressions in an app I work on when updating from Vite 7 to Vite 8. I got an AI to generate a tool to help figuring out what was wrong, and I uploaded it at nicolo-ribaudo.github.io/vite-compare/ in case it's useful for anybody else.

Take a first look at the new @vitest.dev Browser Mode's trace viewer 👀 Design is not final 😄 Thank you, @hiogawa.bsky.social for working on it! main.vitest.dev/guide/browse...

One week after its release, Vite 8 has already been downloaded over 2.6M times 🤯 Rolldown is now running in production across the ecosystem and the adoption curve is just getting started!

Very excited about this update! Tons of new stuff coming 🎉

Dropping 3 announcements in a single talk at Vue Amsterdam this week. @vuejsamsterdam.bsky.social

@voidzero.dev will be releasing a lot of new stuff this week. Follow us if you don’t want to FOMO.

npmx is now in alpha: this is our story, as told by our team and friends

i was matias-capeletto in github when @evanyou.me set up the @vite.dev team. i was patak on discord and social, but i was afraid of breaking all my links in github. i eventually did it. check the mention for @antfu.me, a proper link. mine is plain text. we must move to a proper identity for the web

GitHub just silently cancelled all our outgoing sponsorships from @voidzero.dev - not sure what happened. I just manually re-sponsored everyone we were sponsoring.

PSA: There’s someone trying to impersonate me around Discord servers recently. Make sure to check the Discord ID! My ID is evanyou, without a dot at the end.

first vite team meeting in months 🥹 these are my people, some of the best souls I know In this call @arnaud-barre.bsky.social @bluwy.me @dominikg.dev @hiogawa.bsky.social @patak.dev @sapphi.red @erus.dev ⚡ thanks for always being there for me forever @vite.dev core team 💜

Just doubled @voidzero.dev 's sponsorship to @patak.dev to $2k/mo. Excited to have you back, and proud to be supporting your work of improving the JS ecosystem.

Test tags are coming to Vitest 4.1 (beta)! And they are powerful 💪 main.vitest.dev/guide/test-t...

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...

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!

Vite 7.2 is out! ⚡️ 🗃️ `build.license` option 🔌 proxy + HTTP2 support 💜 and more features and fixes Don't forget to check the complete changelog at github.com/vitejs/vite/...

⚓ Oxlint now supports plugins written in JavaScript ⚓ Developers can customize and extend Oxlint using JavaScript, but at a speed approaching Rust, due to 'raw transfer' between Rust and JS, and other breakthroughs Many ESLint plugins can run without any modification. Read the full post👇

Yo, did you hear, the new SnoopLogg just dropped! v6.0.3 with official support for Deno and uses @rolldown.rs to speed up bundling by 8x and reduce ESM bundle size by 2%. Check it: www.npmjs.com/package/snoo... #nodejs #typescript #javascript

In the next version of Rolldown, bundling will be ~10% faster 🎉 This was achieved by optimizing the semantic scoping process Internal plugins like define and inject now flag when they haven't changed the AST, allowing to skip redundant scope recreation github.com/rolldown/rol...

JSDC 2025 Speaker Reveal 🚀 Creator of Vue.js and Vite, and founder of VoidZero, Evan You will deliver his keynote: “Vite: Beyond a Build Tool.” He’ll dive into why Vite was created, how it became one of the world’s most popular build systems, and what’s next for its ecosystem.

This week's @viteconf.org was a LOT of fun. It rekindled some of the neutrality/plurality magic from the old JSConfEUs. Like Switzerland. Bridging communities & frameworks. Folk cheering each other on, celebrating collaboration 🎉 TechAtBloomberg folk showed up in force - 7 of us!

. @viteconf.org was the first in-person conference I've been to and it set the bar high! Excellent talks and really welcoming atmosphere. Amsterdam is a fantastic city. Thanks to everyone for the geeky JS chats.

Just talked about Vite+ at @viteconf.org - check out more at viteplus.dev :) More detailed announcement on Monday!
