Highlights 💡

No longer watching node_modules

Rspack v1.2 no longer watching the node_modules directory by default. This can greatly reduce the number of files to watch and improve performance.

According to our benchmark repo, this change will:

  • Reduce memory usage by 120MB.
  • Increase dev startup speed by 40%.
  • Increase HMR speed by 20~30.

This change will not affect symlinked resources in monorepo, as symlinked resources are resolved to their real path by default.

Upgrade to SWC v9

The Rust crate swc_core has been upgraded to 9.0.0. Users of the SWC Wasm plugin need to ensure version consistency with the swc_core being used, otherwise, it may lead to unforeseen issues.

For more details, see SWC Plugin Version Unmatched.
