Webpack Code Compression Guide

Webpack has the ability to compress code by using the UglifyJsPlugin plugin. Code compression can be achieved by following these steps:

1. Install the UglifyJsPlugin plugin.

npm install uglifyjs-webpack-plugin --save-dev

1. Import the UglifyJsPlugin plugin in the webpack configuration file.

const UglifyJsPlugin = require('uglifyjs-webpack-plugin');

module.exports = {
  plugins: [
    new UglifyJsPlugin()
  ]
};

1. Rerun the webpack packaging command to minify the code.

webpack --mode production

In this way, Webpack will utilize the UglifyJsPlugin plugin to compress the code, thus reducing the size of the bundled file.
