title: obfuscate code with laravel mix
body: <p>I have a web app with laravel and vuejs.
  I  use laravel-mix and in my <code>webpack.mix.js</code> i have:</p>
  
  <pre><code>const { mix } = require('laravel-mix');
  mix.sourceMaps();
  mix.js('resources/assets/js/app.js', 'public/js')
     .sass('resources/assets/sass/app.scss', 'public/css');
  </code></pre>
  
  <p>now I would obfuscate code, so all my components, how can I do this with laravel-mix?</p>
