title: Is there a way to ignore a file type with Webpack?
body: <p>In creating my art for my website, I have some intermediate files that I want to keep in my "media" folder.</p>
  
  <p>But then webpack starts complaining that it does not know what to do with those files.</p>
  
  <p>Is there an easy way to say, don't worry about any files with the <code>.pdn</code> extension?</p>
  
  <p>I tried these options in my webpack.config.js, and it did not help:</p>
  
  <ol>
  <li><code>{ test: /\.pdn?$/, loader: 'raw', exclude: /.*/}</code></li>
  <li><code>{ test: /\.pdn?$/, exclude: /.*/}</code></li>
  </ol>
