A fast Rust-based web bundler

English | 简体中文

✨ Features

• 🚀 Fast Startup: Based on Rust, the build speed is extremely fast, bringing you the ultimate development experience.
• ⚡ Lightning HMR: With a built-in incremental compilation mechanism, HMR is extremely fast and fully capable of developing large-scale projects.
• 📦 Webpack Interoperable: Compatible with the architecture and ecosystem of webpack, no need to build the ecosystem from scratch.
• 🎨 Batteries Included: Out-of-the-box support for TypeScript, JSX, CSS, CSS Modules, Sass, and more.
• 🛠️ Production Optimization: Various optimization strategies are built in by default, such as tree shaking, minification, etc.
• 🎯 Framework Agnostic: Not bound to any frontend framework, ensuring enough flexibility.

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 project created by Rolldown team, 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.
• The Turbopack project which inspired the AST path logic of Rspack.
