title: Webpack: ExtractTextPlugin: Not to generate separate empty JS file when have several css entry points?
body: <p>I have several CSS entry points: </p>
  
  <pre><code>entry: {
    ...
    styles: [
      ...
    ],
    fonts: [
      ...
    ]
  },
  </code></pre>
  
  <p>and I'm using ExtractTextPlugin to bundle CSS separately:</p>
  
  <pre><code>  new ExtractTextPlugin({
      filename: `[name].bundle.css`
    }),
  </code></pre>
  
  <p>So like output I have 2 CSS files: <strong>styles.css</strong> and <strong>fonts.css</strong> that is correct but also empty <strong>styles.js</strong> and <strong>fonts.js</strong>. Is there a way to not generate empty JS files?</p>
