This plugin uses UglifyJS v3 API (uglify-es) to minify your JavaScript.

Note that webpack contains the same plugin under webpack.optimize.UglifyJsPlugin. This is a standalone version for those that want to control the version of UglifyJS. The documentation is valid apart from the installation instructions in that case.

uglify-es is repalced with terser in Debian (uglify-es is unmaintained).

Node.js is an event-based server-side JavaScript engine.
