Rspack

Use Rspack as a Webpack-compatible, Rust-based bundler for faster builds with migration constraints.

Rspack is a Rust-based bundler aiming for Webpack-compatible configuration with faster builds on large graphs. Teams evaluate it as a incremental migration from Webpack rather than a greenfield default.

Migration checklist: loader/plugin parity, asset handling, dev server behavior, source maps, and output diff against the existing Webpack build.

On interviews: when Rspack is worth evaluating, compatibility risks, framework support, and why benchmarks must use the real repository.

Common pitfalls: assuming drop-in parity; skipping integration tests after switching; unsupported plugins blocking critical features.

The trade-off is build-time reduction versus validation cost and ecosystem gaps.

Checklist:

Compare bundle output to Webpack baseline.
Run integration tests on migrated config.
Measure cold and incremental builds realistically.
Keep rollback path until parity proven.
