title: How to minify all js and css in MEAN.JS for production environment?
body: <p>I have just developed a simple MEAN.JS application. MEAN.JS provides a command <code>grunt build</code> that helps me to minify the js and css files located at the following folders</p>
  
  <pre><code>css: [
      'public/modules/**/css/*.css'
  ],
  js: [
      'public/config.js',
      'public/application.js',
      'public/modules/*/*.js',
      'public/modules/*/*[!tests]*/*.js'
  ]
  </code></pre>
  
  <p>but how about also minifies the third-party libraries, which is installed with <code>bower</code> and located in <code>public/lib/...</code>? All the needed js and css file paths are already inside the MEAN.JS environment config file.</p>
  
  <p>Meanwhile, the minified js file <code>application.min.js</code> is really just "minified", not "uglified", the variables' names are still the same as the original and very long.</p>
  
  <p>In short, has MEAN.JS already provided any ways or functions that can "uglified" all the js and css files including third-party libraries?</p>
