License files being generated even with extractComments = false

• Laravel Mix Version: 6.0.6

Description:

I’m getting app.js.LICENSE.txt and vendor.js.LICENSE.txt files even though I’ve set the terser plugin option extractComments to false

Steps To Reproduce:

npm run watch

My config:

/* jshint node: true */
const mix = require('laravel-mix')
const path = require('path')

/** Mix Options **/
mix.options({
  terser: {
    extractComments: false,
  }
})

/**
 * Frontier Assets
 */
mix
  .js('resources/js/app.js', 'public/js')
  .vue({ version: 2 })
  .postCss('resources/css/app.css', 'public/css')
  .copy('resources/img/', 'public/img/')
  .extract()

// Add version in production build
if (mix.inProduction()) {
  mix.version()
}

/**
 * Custom webpack config.
 */
mix.webpackConfig(require('./webpack.config'))

Contents of webpack.config.js:

/**
 * The Path module.
 */
const path = require('path');

/**
 * Custom Webpack config.
 *
 * Described here, in the separate file, for the IDE support.
 *
 * @see https://gist.github.com/nachodd/4e120492a5ddd56360e8cff9595753ae
 */
module.exports = {
  resolve: {
    alias: {
      '@': path.resolve(__dirname, 'resources/js'),
      '@css': path.resolve(__dirname, 'resources/css'),
    }
  },
  optimization: {
    minimize: true,
  }
};

This should work for what you want to do:

mix.options({
    terser: {
        extractComments: (astNode, comment) => false,
        terserOptions: {
            format: {
                comments: false,
            }
        }
    }
});

try this:

mix.options({
	terser: {
		extractComments: false,
		terserOptions: {
			output: {
				comments: false,
			},
		},
	},
});
