About webpack
webpack is an open source module bundler for JavaScript and related assets, distributed under the MIT license and published to npm. It lives in the JavaScript ecosystem, where the README describes its main purpose as bundling JavaScript files for use in a browser, while also being capable of transforming, bundling, or packaging just about any resource or asset. Loaders let modules arrive in many forms — CommonJS, AMD, ES6 modules, CSS, images, JSON, CoffeeScript, LESS, or custom formats — and the plugin system extends what the build can do.
