Rspack has tons of complex tests. We just migrated from Jest to Rstest and saw about a 30% speed boost. ⚡️
If you’ve been thinking about trying Rstest, now might be a good time to give it a shot.

An implementation of TC39 Stage 3 Import Defer is being worked on in @rspack.dev by @ahabhgk.bsky.social 🎉
This is a performance feature that enables lazy execution of JS modules ⚡
webpack already has (partial) support, so it makes sense for Rspack to achieve parity.

To implement robust mitigations across Geomys, I did a survey of open source project compromises in 2024/2025.
Three root causes dominate: phishing, control handoff, and unsafe GitHub Actions triggers. All three can be systematically avoided.

Jiti is now bundled with Rspack/SWC— smaller bundle size & faster.
Since Rsbuild relies on Jiti for config loading, this also benefits our users. 🥳

Rslib v0.13.3 is ~100ms faster from a tiny change:
Swapping import "typescript" with require('typescript').
It skips Node's cjs-module-lexer overhead. 😅
