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.
