The record

Purpose: Rsbuild is a modern build tool for web applications, powered by Rspack.
Configuration: It supports zero-configuration project setup and offers a configurable build API.
Bundler and compilation: Rsbuild uses Rspack by default and uses SWC to transform and minify JavaScript and TypeScript code.
Frameworks: Framework plugins support React, Vue, Svelte, Solid, and Preact.
Development: Hot module replacement is enabled by default in development mode.
Production optimization: JavaScript and CSS minification are enabled by default for production builds.
Styling integrations: The feature guide lists optional Tailwind CSS and UnoCSS support, along with Sass, Less, and Stylus preprocessing.
Webpack compatibility: Rsbuild is compatible with most webpack plugins and all Rspack plugins.
Module Federation: Rsbuild offers first-class support for Module Federation for developing micro-frontend applications.
Security configuration: The docs warn that enabling CORS for all origins can expose the development server and recommend an allowlist of trusted origins.
Security limitation: The docs warn that publicly deploying production source maps can expose source code and create security risks.
Support: The Rsbuild introduction invites users to chat with the Rstack team and community on Discord.
Online example: The documentation links to a StackBlitz example for trying Rsbuild online.
Runtime requirement: For Rsbuild v2, the quick start guide requires Node.js 20.19+ or 22.12+; Rsbuild v1 requires Node.js 18.12.0 or higher.
