Usage

webpack v4

If you use webpack < 4.2 that has dependency on uglifyjs-webpack-plugin < 1.2.4, you need to set optimization to set uglifyOptions.

const path = require('path');
const LicenseInfoWebpackPlugin = require('license-info-webpack-plugin').default;
const UglifyJsPlugin = require("uglifyjs-webpack-plugin");

module.exports = {
  mode: 'production',
  entry: './src/js/index.js',
  output: {
    path: path.join(__dirname, 'dist/js'),
    filename: '[name].js'
  },
  plugins: [
    new LicenseInfoWebpackPlugin({
      glob: '{LICENSE,license,License}*'
    })
  ]
};

webpack v3

const path = require('path');
const LicenseInfoWebpackPlugin = require('license-info-webpack-plugin').default;
const UglifyJsPlugin = require("uglifyjs-webpack-plugin");

module.exports = {
  entry: './src/js/index.js',
  output: {
    path: path.join(__dirname, 'dist/js'),
    filename: '[name].js'
  },
  plugins: [
    new LicenseInfoWebpackPlugin({
      glob: '{LICENSE,license,License}*'
    }),
    new UglifyJsPlugin({
      uglifyOptions: {
        output: {
          comments: /^\**!|@preserve|@license|@cc_on/
        }
      }
    })
  ]
};

Note

If you use uglifyjs-webpack-plugin@^1.2.4 or webpack has dependency on uglifyjs-webpack-plugin@^1.2.4, you don't need to set uglifyOptions for preserve license comments.
