Credits

Thanks to:

  • The webpack team and community for creating a great bundler and ecosystem from which we draw a lot of inspiration.
  • @sokra for the great work on the webpack project.
  • @ScriptedAlchemy for creating Module Federation and helping Rspack connect with the community.
  • The SWC project created by @kdy1, which powers Rspack's code parsing, transformation and minification.
  • The esbuild project created by @evanw, which inspired the concurrent architecture of Rspack.
  • The NAPI-RS project created by @Brooooooklyn, which powers Rspack's node-binding implementation.
  • The Parcel project created by @devongovett which is the pioneer of rust bundler and inspired Rspack's incremental rebuild design.
  • The Vite project created by Evan You which inspired Rspack's compatibility design of webpack's ecosystem.
  • The rolldown-legacy project created by old Rolldown team, It's the predecessor of the rolldown project, which explores the possibility of making a performant bundler in Rust with Rollup-compatible API. It inspires the design principles of Rspack.
  • The html-webpack-plugin project created by @jantimon, @rspack/html-plugin is a fork of html-webpack-plugin to avoid some webpack API usage not supported in Rspack.
