Building a library with WebAssembly?
🧙♂️Rslib 1.0 beta supports `.wasm` with two output modes for different consumer needs:
- `compile` adds runtime loading glue
- `preserve` keeps the import for the consumer's bundler
Simple source. Consumer-ready output. 🦀
Rstack is a lightning-fast JavaScript toolchain that includes Rspack, Rsbuild, Rslib, Rspress, Rsdoctor, Rstest and Rslint.

- Rspack v2.1.8 is out! - Faster CSS HMR (50ms -> 5ms) - 3–4× faster copy plugin - Configurable cache location - Reduced memory usage for warnings - 19 bug fixes
- Another way Rspack speeds up the dev workflow ⚡Testing with jsdom can be slow because every isolated worker loads its large dependency graph. In the next release, Rstest will support opt-in prebundling of jsdom & happy-dom for reuse across workers. Benchmark shows 33–53% faster test runs 🚀
- 🦀 Rstest now uses Yuku instead of Acorn for V8 coverage parsing. On a real Rsbuild test suite: 8.74s → 3.35s median 378/378 tests passing Unchanged coverage totals A parser swap, with a 61.7% faster coverage run. ⚡️The Yuku toolchain (parser, codegen, etc.) crossed 1M weekly downloads. yuku.fyi
- Turns out Bundlephobia has been using Rspack under the hood for months 👀 bundlephobia.com Fast package analysis, powered by Rspack. Thanks @_pastelsky for bringing Rspack to Bundlephobia 🦀
