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!

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

🚨 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 🚀

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/...

Picture of VS Code with an open minimal Vite project. The Vite config only sets `experimental.enableNativePlugin` to "resolver" with a comment saying "// or true, either is necessary", and "resolve.tsconfigPaths" to true. The tsconfig.json has `compilerOptions.paths` set to `{ "app/*": ["./src/app/*"]`. Eventually, the path resolution is used automatically (wtih autocomplete too!) in src/main.ts when using `import { App } from "app/my-app.ts`, instead of `import { App } from "./src/app/my-app.ts"`!

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 🙌

Add rolldown-vite support by sapphi-red · Pull Request #128 · davidmyersdev/vite-plugin-node-polyfills While this plugin mostly works with rolldown-vite, there are a few areas where it could leverage Rolldown's built-in features to improve performance. This PR includes the following changes: Us...

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! 🙌

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 👀

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)

Yes, although we found some of the optimizations better implemented in the minifier instead of the bundler itself. We do port a lot of tests from Rollup!

Try it out in your @vite.dev projects today and share your feedback with us!

You can report issues in the `rolldown-vite` repository (github.com/vitejs/rolld...), or join us on Discord (chat.rolldown.rs).

Rolldown-Vite is a drop-in replacement of the stable channel Vite, with greatly improved production build performance (3~16x in real world apps)

It will become the default Vite version in the near future when it stabilizes.

Announcing Rolldown-Vite We are building the next generation of JavaScript tooling

Today we are excited to announce Rolldown-Vite: a technical preview of the version of @vite.dev entirely powered by the Rust stack we built over the past year (Oxc + @rolldown.rs)

voidzero.dev/posts/announ...

Screenshot of the blog post quote saying: This is truly amazing: we are not talking about refactoring our code or spending time understanding and trying to fit new tools. We are talking about drop-in replacements that could give us a 64% reduction in a CI pipeline (referring to only build + linting).

Happy to see Mercedes Benz adopting modern tooling such as @rolldown.rs and Oxc in their workflow, as well as going the extra mile and sharing their results!

Up to 64% CI pipeline time reduction is impressive 👀

And more per improvements are yet to come 🤯
