Big day for the Rspack ecosystem! 🎉
TanStack Start is an amazing full-stack framework, and Rspack users now have a first-class full-stack option.
Huge thanks to the TanStack team, especially @schanuelmiller, and @CongCongPan from the Rspack team for shipping this so fast and so well. 🫡
i'm sad and confused why claude code would remove /simplify. /simplify is the most useful built in skill, and as it's name, it's simple.
Instead now it's going to be /code-review with different effort levels but:
- agents are not good enough to write clean code yet, and /simplify still helps majorly
- sometimes you want to simplify your code without a full on review
- /simplify doesn't need effort level, additional prompt, or comment replies.

❓Did you know you can write “in-source tests” in JavaScript
Rstest supports in-source tests — write your test right next to the code. Test code is stripped in production builds. Zero bundle cost. ⚡️
Rust-style DX, now in your JS toolchain 🦀

Large-scale AI migration is changing how we think about rewrites.
Looking back at Rspack, rewriting webpack in Rust was never just about translating code.
When we rewrote webpack in Rust, many of us were still learning Rust, webpack internals, or both. The project itself became a training ground.
People grew into experts. We re-examined webpack’s design choices. We found Rust-native implementations. We contributed back to projects like webpack core, plugins, NAPI, SWC and Lightning CSS.
The final result was not just “webpack in Rust”. It was a team, an ecosystem, and a new generation of bundler expertise.
Rspack 2.0 has landed 🦀
The growth since 1.0 is wild:
📈 100K → 5M weekly downloads
⚡️ ~100% faster builds
📉 devServer: 192 deps → 1
And new stuff hits hard:
🧩 Pure ESM core, modern ESM library output
⚛️ Experimental RSC support
...
Lean, Fast, Modern Web Bundling 🚀
Rspack / Rsbuild 2.0 stable is coming next week!
One key improvement: we've trimmed npm deps across core packages to the bare minimum. This lowers supply chain risk and speeds up installs.
