How to minify a source file (Javascript) into a minify file using uglifyjs-webpack

Question

I want to minify my files using uglifyjs-webpack.

For example I have a source file core/js/test and want to minify it and send it to min/js/test.

Just using a source and respective output, how do I use it with webpack.

Answer 1

I often just use the optimization: {minimize: true} option (see this) since webpack 4.

const path = require("path"); 

module.exports = {
  context: __dirname,
  entry: "/origin/main.js",
  output: {
      path: path.resolve("./min/js/"),
      filename: "test.js"
  },
  optimization: {
    minimize: false
  }
};

However, webpack still allows you to override the default implementation using the UglifyjsWebpackPlugin. I'd advise you to have a look at the docs in here, they seem to explain it quite alright.
