Reviewer scorecard
“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“For webpack-heavy projects, Rspack provides the biggest speed improvement with the least migration effort.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Rust-based JS tooling replacing JavaScript tooling is the trend. Rspack, Biome, and SWC prove it works.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
