Remotion is working on experimental Rspack support 👀

Great to see Tailwind CSS shipping an official @tailwindcss/webpack package 👏

It’s implemented as a webpack loader, which means it works in Rspack and Turbopack as well.

Big shoutout to @timneutkens.bsky.social for making this happen 🙌

Smaller Module Federation bundles are here!

Rspack 2.0 supports tree-shaking for shared code 🔥

Nice! Also remember to like @rspack.dev on @npmx.dev! 😊 I got the first like! Again thanks for your great work!

Rsbuild 2.0 beta cuts dependencies from 13 → 4, MF runtime is now an optional peer dependency ✨

Meteor.js 3.4 with @rspack.dev is out! 🚀

4x faster builds. 50% smaller bundles. Tree shaking, full ESM support, and HMR.

Rspack + RSC is now prototyped in the 2.0 alpha. We're continuing to iterate on stability and docs 🔧

In Rsbuild 2.0.0-alpha.0, install size is 2.3 MB smaller by removing the CJS build and making core-js optional.

We'll keep trimming it down ✂️

Rstack Q1 roadmap 💡

• Rspack 2.0 beta
• Rsbuild 2.0 beta
• Rspress 2.0 stable
• Rstack Skills
• RSC support
• Rstest browser mode
• Faster persistent cache
• ESLint compatibility in Rslint
• Tree-shaking analysis in Rsdoctor

Rspack and Rsbuild core packages are now pure ESM.

Already merged, will be released in v2 🌟

We just added @tailwindcss.com as an optional tool in create-rsbuild ❤️

Rstest → SWC core 🎉

2.3s →1.7s (35% faster than Jest)

Announcing Rspack 1.7 - Rspack Fast Rust-based web bundler

Rspack 1.7 is out 🎉

The final minor release of the 1.x series, focused on stability and polish.

Next stop. Rspack 2.0 in 2026 🦀

rspack.rs/blog/announc...

⏰ Rspack 1.7 is coming tomorrow.

The last minor release before 2.0.

In the next release, Rsbuild's error overlay can now show runtime errors.

When your app throws at runtime, the error appears instantly in the overlay, helping you locate problems sooner.

Opt in using `dev.client.overlay.runtime = true`.

The SWC parser is now 65% faster than 6 months ago and 104% faster than a year ago🚀

Huge kudos to @kdy1.bsky.social and @c_punisher 👏

In the next release, Rspack adds support for the new Import Bytes proposal:

Goodbye Webpack, Hello Rspack (and 80% Faster Builds) We migrated our massive frontend monorepo from Webpack to Rspack, cutting startup time from three minutes to just ten seconds and reducing build times by 80%. Learn how we made the switch…

Thanks to the Mews team for sharing their migration experience 🙌: developers.mews.com/goodbye-webp...

From a blog post by the Mews team:

"Migrating from Webpack to Rspack completely transformed our frontend developer experience. Builds that once took five minutes now finish in under one, and hot reloads that used to take over ten seconds now feel instant."

Rspack v1.6.7 is out:

✨ Support for import.meta.resolve
✨ Support for import.meta.dirname
✨ Support for import.meta.filename
📍 Relative source map paths
🛠️ 10 bug fixes

In the next release, Rsbuild adds a new "printFileSize.diff" option to show size changes between the current build and the previous one.

Storybook CLI now auto-detects Rsbuild projects and installs deps like storybook-react-rsbuild for you. Huge shoutout to the @storybook.js.org team!

In the next release, Rspack will generate a more compact module factory format that trims the wrapper function.

Benchmarks show this reduces bundle size by about 1% before gzip, though the effect after gzip is minimal. 😉

Rspress v2 RC is live across all Rstack sites. 🎉

A few fixes are in progress. The final release will ship once everything is polished.

10 million monthly downloads. Huge thanks to everyone trusting Rspack. ❤️
