Webpack

Webpack is a free and open-source JavaScript module that can also be applied to HTML and CSS. Webpack can be run on the Linux, macOS, and Windows operating systems.

As a module bundler, Webpack can be used with webpack.config.js to generate dependency graphs and define rules for tasks performed on a site. It is primarily used by developers to load, transform, and package modules for in-browser use.

Node.js is needed to use Webpack. However, it is supported by all browsers that are ES5-compliant.
