Rolldown v1.0.0-beta.39 has been released! ⚡ macOS Performance Boost: 10%-30% faster bundling, up to 45% in extreme cases. 🎯 Cross-Chunk Optimization: Support for __NO_SIDE_EFFECTS__ annotation, as well as better tree-shaking across module boundaries and more efficient DCE

tsgolint mentioned during @jakebailey.dev's talk about ts-go at @squiggleconf.com ✅ If you didn't try it out, time to jump into type-aware linting with Oxlint. 👀 oxc.rs/docs/guide/u...

It was a pleasure to be among such a great line-up. Thank you for having me, @squiggleconf.com! 🙌 You can find the slides below. If you have any questions, feel free to post here or send me a DM ☺️ github.com/TheAlexLicht...

To everyone attending @squiggleconf.com in the next two days - enjoy two days packed with knowledge around Web Dev Tooling. Proud to support the non-profit conference 🙏🏻

A special message from the creator himself! 🚀 Hear directly from @evanyou.me, the mind behind @vite.dev and founder of @voidzero.dev, what to expect at this year's ViteConf! Secure your spot to experience the future of web development. viteconf.amsterdam

In the next version of @rolldown.rs, more accurate source maps are generated Example: When an error occurs during property access Before, the source map highlighted the right line, but not the property that caused issues. Now it points to the correct property, improving debugging experience and DX

To better communicate our design choices for the up-coming formatter: github.com/oxc-project/...

Rolldown drops CJS support! From the latest version of @rolldown.rs (1.0.0-beta.36) on, Rolldown will only be released in the ESM format. The required Node version has also been bumped to align with @vite.dev (20.19+ and 22.12+). Node 18 has been dropped due to being EOL since April.

⚡ Speaker highlight: Jim Dummet, Core Team at Oxc As a JS Dev, every tool seems to be rewritten in Rust. But If our tools migrate to another language, will we be ale to customize them? Jim explains how Oxc plans to allow customization via JS plugins, all while maintaining exceptional performance!

⚡ Panel highlight: Future of Web Development This panel is a deep dive with creators and industry leaders to discuss the biggest trends, challenges, and opportunities in web dev. What do YOU want them to talk about? Drop your questions in the comments below make sure we cover what matters most!

Kicking off the @voidzero.dev offsite! The whole team for the first time in a single room 👀🙌🏻

⚡ Speaker highlight: Alexander Lichter, DevRel at @voidzero.dev Rolldown will be the default in a future Vite major @thealexlichter.com will share what is different about @rolldown.rs, how it replaces both esbuild & Rollup while keeping compat, and what this means for end users beyond faster builds

PLAID Moved to @rolldown.rs & Cut Build Times by 97% PLAID was using Rollup for server-side bundling, which could take up to 20s to complete each time! The team wanted to reduce wait times. Learn why the PLAID team migrated to Rolldown. voidzero.dev/posts/case-s...

⚓️Oxlint with type-aware linting is here ⚓️ ◆ 40 type-aware rules supported, including the famous `no-floating-promises` rule ◆ Built on top of `tsgolint` and `ts-go` ◆ Brings speed improvement & correctness Read more in the latest announcement voidzero.dev/posts/announ...

`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

Remember how @gitlab.com got 2.6x faster builds and ~100x less memory consumption when using @rolldown.rs? Now, with all the native plugins enabled, they are down to 22s. That is ~7x faster than Vite, ~half the time compared to using native resolver before and 43x faster than their webpack build 🔥

What's new in ViteLand? Our July 2025 recap is out. 🎉 Announcing 1st in-person @viteconf.org in Amsterdam 📈 @vite.dev surpassing webpack's downloads ⏩ Major performance boosts for @rolldown.rs 🔥 Type-aware linting & custom rules for Oxlint 👀 and more Read the post: voidzero.dev/posts/whats-...

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...

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 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.

⚡ Speaker highlight: Evan You ViteConf wouldn’t be the same without @evanyou.me, creator of Vue & Vite. His talks always drop major news 👀 This year, he'll reveal how Vite is evolving beyond a build tool into a full Rust-based toolchain. You won't want to miss it! More info on viteconf.amsterdam

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 👏

> OXC is not only more performant but also had much nicer ergonomics endform.dev/blog/js-is-b...

✨ 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...

🚨 Speaker Alert 🚨 We're incredibly proud to bring together an exceptional group of speakers who are pushing the boundaries of web development with @vite.dev Over the next few days, we'll be highlighting the incredible speakers who will be on our stage on Oct 9-10! Stay tuned 🚀 viteconf.amsterdam

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/...

Did you know that Rolldown-Vite supports tsconfig path resolution out of the box? Use the path resolutions defined in your tsconfig by setting `resolve.tsconfigPaths`. The only requirement? You must use native plugins, either only the resolver or all No extra plugin needed 🙌

The new v0.24 of vite-plugin-node-polyfills now uses more of @rolldown.rs's built-in features, e.g. inject, which improves performance when detecting it is running via the Rolldown-powered @vite.dev! 🙌 More in the PR from @sapphi.red

As part of our open source pledge, we financially support our critical dependencies and important projects / initiatives for the web ecosystem.

Wow! @posthog.com moved from @eslint.org to Oxlint and achieved 97% faster linting. Instead of 7.7s, the pre-commit hook takes 230ms now 👀 github.com/PostHog/post...

The @rolldown.rs powered @vite.js version is out for a while, giving 2~16x build speed improvements! If you ever wondered how to switch, then no worries. I show you how in less than 90 seconds! Also, one more goodie for React users (switching to the Oxc-based Vite plugin)
