Amazing collab with the friendly TanStack team! 🤝 Their unique RSC approach breaks traditional root-level limits—it's brilliant. Rsbuild & Rspack are evolving fast. We're committed to being the universal RSC infra to support more frameworks! 🚀

❓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 🦀 #JavaScript #Rstest #Rspack

Mind blown! 🤯 I've been using codspeed's MCP, and my AI Agent used its insights to optimize a case in rspack-sources—boosting performance by a staggering 98.96%! Seriously, my god, everyone needs to give codspeed a try right now. 👇 github.com/rstackjs/rspack-s…

We rely on GitHub every day, so it's really exciting to see Rspack being used by GitHub as well. ❤️

We have a good relationship with the @rspack_dev team (they support Rspack in Next.js), and will work with them on aligning plugin APIs where it makes sense. We're shifting more focus towards ecosystem compatibility now that we've finally shipped.

Wrote an article about how React Server Components integrate with a bundler. It's a deep dive into how code splitting works, how RSCs eliminate network waterfalls, how environment directives like "use client" work, CSS loading, etc. Check it out! devongovett.me/blog/parcel-r…

Frustrating that using `napi_create_object` & `napi_set_property` in N-API is way slower than converting data to a JSON string in Rust, passing it to JavaScript, and parsing it with `JSON.parse`. 🤣
