In the next release, Rsbuild's error overlay can now show runtime errors.
When your app throws at runtime, the error appears instantly in the overlay, helping you locate problems sooner.
Opt in using `dev.client.overlay.runtime = true`.

"Migrating from Webpack to Rspack completely transformed our frontend developer experience. Builds that once took five minutes now finish in under one, and hot reloads that used to take over ten seconds now feel instant."

In the next release, Rspack will generate a more compact module factory format that trims the wrapper function.
Benchmarks show this reduces bundle size by about 1% before gzip, though the effect after gzip is minimal. 😉

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.
