How to change `sourceMappingURL` by using webpack
<p>My production webpack configuration is:</p>

<pre><code>{
  output: {
    publicPath: "https://cdn.example.com/sub-directory/",
    filename: '[name]-[chunkhash].min.js'
  },

  devtool: 'source-map',

  plugins: [
    new webpack.optimize.UglifyJsPlugin()
  ]
}
</code></pre>

<p>Now I have two files <code>app-12345.min.js</code> and <code>app-12345.min.js.map</code>.</p>

<p>I also have automatically generated CDN URL <code>https://cdn.example.com/sub-directory/app-12345.min.js</code> for main script.</p>

<p>But <code>sourceMappingURL</code> is still relative path <code>//# sourceMappingURL=app-12345.min.js.map</code> and not accessible directly in browser.</p>

<p>My question is how I can set <code>sourceMappingURL</code> as absolute automatically generated path?</p>
