This project is a CommonJS module bundler and resolver designed to combine interdependent JavaScript files into a single script for execution in web browsers. It functions as a Node.js JavaScript bundler that emulates server-side core modules and resolves dependencies to ensure compatibility between server-side logic and browser environments.
The system features an extensible bundling pipeline and a browser-side module resolver. It provides a plugin architecture for transforming source code and a source map generator to correlate bundled output back to original files for debugging.
The project covers capabilities for client-side dependency management, asset processing pipelines, and bundle splitting to exclude specific dependencies from the internal graph. It also supports universal module definitions for standalone exports and a stream-based transformation pipeline for modifying source text.
