What is it?
Rspack is a web bundler written in Rust. It keeps a webpack-style API, so projects can move from webpack with limited changes, and it can use many existing webpack plugins and loaders.
The bundler includes incremental compilation for fast hot module replacement, built-in production optimizations such as tree shaking and minification, and first-class support for Module Federation. It is not tied to any frontend framework.
Rspack is part of the Rstack toolchain, which also includes Rsbuild, Rslib, Rspress, Rstest and Rslint. It is distributed as the @rspack/core npm package and as Rust crates.
