Nitro ❤️ Rsbuild, now on nightly too. Build full-stack apps like TanStack Start with Nitro + Rsbuild and deploy them anywhere. Platform dev emulation (like miniflare) and other features works with every builder!

After almost a month of work: the moduix docs, reimagined. Still powered by our beloved Rspress, now with a new design, live component anatomy, live CSS variables and theme presets. For React, Solid and Vue. Link below 👇

最近深入支持了一些顶流 Agentic Web 工程，也是顺利都迁移到了 Rsbuild 2.x： - Chatgpt (Rsbuild + React Router) - Copilot (Rsbuild+ Tanstack Start) - 豆包 (Rsbuild + Modern.js) 一些小发现： - 前端没全死，复杂业务仍有挑战 - 在八位数代码量的大仓里，现有工具都不够快 - 多 agent 并行开发，内存成为新瓶颈 - 普遍使用 SSR - 从零写一个超大型工程的时间被压缩至一两年 - 构建工具需要更好的按需编译和持久化缓存支持更大的研发规模 - 未来可能有分布式编译或全新的 bundler 架构来突破上限

SWC Next is now in Rspack! Just the parser for now, but this is only the beginning. Get ready for an even faster Rspack

Rspack 2.3 will use SWC Next for JavaScript parsing. We plan to gradually migrate more of Rspack's internals to SWC Next and introduce a new swc-next-loader that supports custom transform plugins written in JavaScript.

SWC Next is here! Today, customizing how your code is transformed often means using Babel plugins or writing Wasm plugins for SWC. I believe the next generation of JS compilers should combine Rust's performance with the flexibility to write custom transform plugins in JavaScript. SWC Next's flat AST enables efficient data exchange between Rust and JS, laying the groundwork for fast JS plugins 🚀

Introducing SWC Next: the foundation for SWC’s next major version, built on a new architecture inspired by Yuku. - Up to 3x faster native parsing - Up to 10x faster parsing through the JavaScript API - A flat, ESTree-based AST designed for speed, memory efficiency, and JavaScript extensibility Starting with parsing, we’re bringing the rest of SWC to this new architecture. Built together by the SWC and Rstack teams.

After migration to @rspack_dev Rsbuild, then try Rstest as a replacement for Jest. This reuse your Rsbuild config making your test runner behavior closer to your build and has single source. You can delegate the task to the agent. Meaning the annoying works when doing migration like replacing jest references to rs, changing the mocks, rewriting snapshots, etc majority of these will be handled by your agent. Just make sure you install Rstest skills and the agent is doing loop. Our average shard with jest in CI is around 11mins. Down to 2 mins with rstest. Its just fast!

Please don’t use rspack, use rsbuild. Only ever use rspack directly if you are porting off webpack.

Some real-world gains from migrating to Rspack 👇

Since, it’s easy to miss something in a complex pipeline, making Rspack more Vite-ish was important. The results: - JS requests down by ~95% - Bundle size (uncompressed) down by 5~21% - Bundle size (compressed) down by ~40% - Dev server got faster in about 2.5x [7/8]
