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.
