Rspack

11x faster and minimal migration costs 🚀

ECMAScript excitement 😉 Congrats to @magic_akari & @kdy1dev on shipping parsing support for TC39 Stage 3 `import defer` in SWC 🎉 import defer * as ns from "mod" This feature improves performance via lazy evaluation of (eagerly fetched) modules 👍 github.com/swc-project/sw…

Rsbuild's next release will reduce startup time by ~25ms 🥳

Rspack v1.4.9 is out: 🎉 We optimized Rust dependencies and build flags, reducing install size across all platforms. More size improvements are coming soon. 🍀

In the next release, Rspack will be able to emit errors for duplicate ESM exports:

While optimizing the binary size of @rspack_dev , we also helped reduce the size of @swc/core(41.9MB -> 37.8MB), benefiting all SWC users in the process.

If you are using @swc_rs for your app, please consider donating via github.com/sponsors/swc-p… or opencollective.com/swc ! If you are not making money out of it, please give us a star on Github. github.com/swc-project/swc

🚀 Rspack v1.4.8 is out! We've implemented a Rust watcher to replace the original watchpack package, making HMR ~10% faster. Combined with lazy compilation for lightning-fast dev experience ⚡

While investigating @rspack_dev performance in Next.js, SyMind found a simple opportunity to add caching that speeds up webpack >6%! github.com/vercel/next.js… An awesome contribution for those still stuck on webpack.

Reusable themes in @rspack_dev Rspress v2 are such a life saver. With @grabbou we wanted to put Callstack brand on our OSS websites and by leveraging Repress, it's as easy as applying a plugin.

I think I found the way to make @swc_rs Wasm plugin backward compatible to some amount. It’s not 100%, but it will make it compatible for most AST modifications. I’ll try and report back.

Help us prioritize: which Rspack experimental feature would you like to see stabilized first?
