Rslib

English | 简体中文

Rslib is a library development tool based on Rsbuild.

It gives developers a simple way to create JavaScript libraries and UI component libraries, and provides tool integrations and best practices for building, debugging, documentation, and testing throughout library development.

🔥 Features

Rslib has the following features:

Easy to configure: Out-of-the-box tooling enables developers to build libraries with zero configuration. Rslib also provides a set of semantic build configurations that can be extended as project needs grow.
Performance-focused: Powered by Rspack, it integrates high-performance Rust-based tools from the community, including SWC and Lightning CSS, delivering first-class build speed and development experience.
Plugin ecosystem: Supports Rsbuild plugins, Rspack plugins, and webpack plugins, allowing developers to reuse existing plugin ecosystems and continue using familiar development workflows and engineering practices.
Flexible outputs: Designed around the diverse ways libraries are published and consumed, it supports flexible build output configuration for different runtimes, distribution methods, and downstream build tools to meet the delivery needs of different types of libraries.
Framework agnostic: Decoupled from frontend UI frameworks, it supports React, Vue, Svelte, Solid, and other frameworks through plugins, allowing developers to build component libraries for different frameworks with a consistent configuration and development workflow.
