Introduction#

Rslib is a library development tool that leverages the well-designed configurations and plugins of Rsbuild, empowering library developers to take advantage of the extensive knowledge and ecosystem of webpack and Rspack.

Rslib provides a comprehensive set of build features for library development, including:

• Compilation of diverse languages: TypeScript, JSX, Sass, Less, CSS Modules, Wasm, and more.
• Flexible build modes: Bundle and bundleless options to meet varying needs.
• Multiple output formats: ESM, CJS, and UMD for maximum compatibility.
• Declaration file generation: Including isolated declarations.
• Advanced features: Module Federation, asset compression, PostCSS, Lightning CSS, and more.

🔥 Features#

Rslib has the following features:

• Easy to Configure: Rslib aims to simplify library development by offering ready-to-use build capabilities, enabling developers to kickstart their library projects with minimal configuration.

• Performance Oriented: Rslib integrates high-performance Rust-based tools from the community, including Rspack, SWC and Lightning CSS, to deliver first-class build speed and development experience.

• Plugin Ecosystem: Powered by Rsbuild, Rslib benefits from a lightweight plugin system and a collection of high-quality official plugins. Furthermore, Rsbuild's compatibility with most webpack plugins and all Rspack plugins allows library developers to seamlessly integrate existing community or in-house plugins into their library projects.

🎯 Ecosystem#

Rslib is implemented based on Rsbuild and fully reuses the capabilities and ecology of Rsbuild.
