CommonJS Everywhere Bundler

commonjs-everywhere (cjsify) is a browser bundler designed for CommonJS modules, providing features like source map generation from minified bundles back to original source code, module aliasing for browser-specific overrides, and an extensible architecture to support various compile-to-JavaScript languages. Its current stable version is 0.9.7, and it appears to be unmaintained given its reliance on Node.js 0.8.x, 0.9.x, or 0.10.x (versions that were released over a decade ago and are long End-of-Life). Key differentiators in its time included robust source map support from minified to original sources, the ability to define custom handlers for non-JavaScript files (such as CoffeeScript and JSON, which were included by default), and an efficient watch mode that only rebuilt changed dependencies. It served as an early alternative to tools like Browserify for enabling Node.js-style module loading in browser environments.
