Rspack is a Rust-based bundler compatible with webpack. 5-10x faster builds while maintaining webpack plugin and loader compatibility.
Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“For webpack-heavy projects, Rspack provides the biggest speed improvement with the least migration effort.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Rust-based JS tooling replacing JavaScript tooling is the trend. Rspack, Biome, and SWC prove it works.”
