`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!

Faster Type-Aware Lint Rules: Biome vs. Oxlint ESLint and TypeScript-ESLint are indispensable. Their type-aware rules—no-floating-promises, the entire no-unsafe-* family, and dozens more—have become the back

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

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 😀

Speaker Card of Evan You showing "ViteConf 2025", his name, the title "Creator of Vite" and his talk title "Vite: Beyond a Build Tool"

⚡ 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!

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!

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!

chore(frontend): Migrate from 🐌 ESLint to ⚡ Oxlint by Twixes · Pull Request #33714 · PostHog/posthog Problem Any commit to the PostHog frontend is painful. Here's how long it takes to lint a staged TypeScript file, as part of the pre-commit hooks: > time pnpm eslint frontend/src/scenes/max/...

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 👀

Prettier 3.6: Experimental fast CLI and new OXC and Hermes plugins! · Prettier This release includes several important feature additions that we're excited to share with you.

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

chore(release): oxlint v1.0 stable by Boshen · Pull Request #11581 · oxc-project/oxc

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!

Goal of the current quarter is to make it work, make it more stable. Next quarter is to improve bundle size.

Our goal is to establish the classic compiler pipeline so that each phase of parse -> transform -> bundle -> minify can be optimized individually, but these phases can share information for more advanced optimization.

It'll take more time to develop, but things should get better.

That's a pretty big codebase!

My appetite grew ;-)

Thank you!

Thank you!

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!

chore: use tsdown by sapphi-red · Pull Request #20065 · vitejs/vite Description This PR replaces unbuild with tsdown. After #19925, rolldown will be used in place of rollup. It would nice to use rolldown for other packages as well so that the behavior is consistent...

Oxc -> Rolldown -> tsdown -> Vite

Thank you. The conclusion is to add another code path to get the module type of a file, no matter how it is resolved from. `ESM_FILE_FORMAT(url)` from the esm spec.

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.

Oh nice! Thank you for using oxc!
