If you write JS or TS, many tools you use are being rewritten in Rust. While Rust offers speed, it might limit our control over tools. In this talk, I’ll explore how Oxc (#Vite compiler) balances #Rust #performance with #javascript plugin customization

First of these optimizations rolled out in v1.15.0 with a reduced scope. Next version of oxlint will be even faster: github.com/oxc-project/... On my laptop: ~15% faster on `oven-sh/bun`, ~9% faster on `microsoft/vscode`, ~11% faster on `posthog/posthog`, and ~8% faster on `elastic/kibana`

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

What's new in ViteLand? Our August 2025 recap is out 👣 Big steps for Oxlint: Type-aware linting preview & custom JS plugins roadmap 🖼️ @vitest.dev has visual regression support in beta ⏩ Native plugins enabled by default in rolldown-vite 🤌 Smaller bundles due to @rolldown.rs and Oxc 👀 and more

Vitest 4 runs simple test files faster! You can already check it out by installing Vitest 4 beta. On average, Vitest now takes 25% less time to start the test. Due to parallelisation, the overall time difference can vary. We are focusing our efforts on improving the time even more in the next beta!

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...

Trying some new oxlint optimizations. This PR has gone over several iterations in the last few months and the core idea is simple: don't run rules for files if they don't apply (using an AST node bitset lookup). The result: linting is around 15% faster in practice.

This is really, really exciting work - and a great write-up! 👏

Type-aware linting is a fast-moving space with multiple experimental approaches, several recent changes, and potentially confusing names. This is a well-written article that describes Oxc's approach and helps clarify the overall landscape 👍

Announcing Oxlint Type-Aware Preview oxc.rs/blog/2025-08...

Good news from ESLint! The 10 years old parallel linting issue is finally resolved. Issue: github.com/eslint/eslin... PR: github.com/eslint/eslin...

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

`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

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-...

I agree that the direction to bet on ts-go seems better. In any case, I'm excited for fast type-aware linting: www.solberg.is/fast-type-aw...

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...

⚡ 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

✂️ Knip v5.62.0 is out → Many plugins updated (Vite, Biome, ESLint, Angular) → Nice bunch of smaller improvements & bugfixes 5️⃣0️⃣0️⃣ releases, who would've thought... Massive shout-out to contributors & supporters, thank you! ❤️ Knip: knip.dev Changelog: github.com/webpro-nl/kn...

TypeScript! Go! Jake is a fountain of knowledge on TypeScript and I thoroughly enjoyed this interview. Thanks again @jakebailey.dev for coming on and being awesome!

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/...

Introducing tsl, an extension of tsc for type-aware linting! Want to speed up your ESLint time without losing the great type-aware rules from @typescript-eslint.io? Run `bunx tsl --migrate` to try it out! github.com/ArnaudBarre/...

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...

After running "oxc-parser" against almost 200k files I had on my laptop and reporting tens of issues that have been closed one after the other, you can now use OXC to speedup Prettier 🚀 Thanks @boshen.github.io & many others, it was a fun project!

Congrats folks! Been using it for a year or so and it's been great

We're thrilled to announce the first stable release of Oxlint - version 1.0! Our Rust-powered JavaScript/TypeScript linter delivers 50~100x faster performance than ESLint with 500+ rules and zero configuration required. Time to give it a try! voidzero.dev/posts/announ...

Getting ready for Oxlint v1.0. No extra features, stability and performance are the key features. github.com/oxc-project/...

Thank you for trying out @rolldown.rs! github.com/vitejs/rolld...

I ran cargo-shear on Turbopack's codebase. It worked really well! github.com/vercel/next.... Thanks for creating such an awesome little tool, @boshen.github.io!

For the Oxlint 1.0 announcement, I'd like to show more real world performance numbers on large repos. If Oxlint has been satisfactory, would you be keen to send me the numbers Oxlint reports at the end? If you have never tried Oxlint but has a large repo: `npx oxlint@latest`.

An interesting how it started, how it is going story ... I got @ mentioned by @webpro.nl on May 15, 2 weeks later now we are collaborating on a secret project @voidzero.dev!

Oxc -> Rolldown -> tsdown -> Vite github.com/vitejs/vite/...

Is there a resource for publishing dual cjs esm packages, where you mark a subdirectory module type with a package.json file? Here is my understanding, but may be wrong. github.com/oxc-project/...

Recent updates from cargo shear: * Removed 1089 unused dependencies in Discord's internal Rust codebase (!!) * Runs 1.2x faster by adding mimalloc to the prebuilt binary * Added `--expand` to expand macros * Finds more dependency usages in odd places github.com/Boshen/cargo...

🐣 Early Easter gift? The Oxc IntelliJ plugin has been released! All @webstorm.jetbrains.com (and other JetBrains IDE) users who are looking for improved Oxlint DX in their editor - this is your chance! And let us know if anything is missing 🙌🏻

Now supporting OXC - a high-performance JavaScript toolchain written in Rust. To help you lint 50-100x faster! (Amongst other things!)

On Oxlint JS plugins: we've created a survey to gather requirements and would love to hear your thoughts. The linked discussion includes background information and potential approaches we could take. github.com/oxc-project/...

I'm starting "This week in Oxc" to improve roadmap visibility. Feel free to subscribe to this thread. github.com/oxc-project/...

In the latest version of the `oxc` VS Code extension (0.16.5), lint fixes now use the provided fix message whenever possible, making it much more clear what the fix will do. Previously, this just appeared as "Fix XYZ problem".

Hello world!

This week's video is a bit more general. After covering *patching* packages a while ago, it is the time to talk about package *overrides* - especially why & how it works. And of course, a great example to showcase it is using @rolldown.rs + @vite.dev + @pkg.pr.new 🔥 youtu.be/8CS8PKB9rAQ Tune in!

🎉 Excited to announce that I'm joining VoidZero as DevRel! As I was following the project from early on, I couldn't say no to the chance when @evanyou.me reached out. I can't wait to share all the incredible things lined up for @rolldown.rs, OXC, @vite.dev, and @vitest.dev 👀

Finally got oxc-parser to work on stackblitz. stackblitz.com/edit/oxc-par...

🌟 Oxlint is now in beta with 500+ built-in rules and 2X faster #JavaScript linting. Next up: custom plugin support and improved IDE integration: socket.dev/blog/oxlint-... @boshen.github.io @evanyou.me

Announcing Oxlint Beta: oxc.rs/blog/2025-03...

Started experimenting with rolldown for Nitro v3 🔥 (with Vite support coming soon as well)

500 Oxlint rules. What a remarkable achievement by everyone who has contributed to OXC. It was only 11 rules when I completed the prototype back in June 2022.
