title: Webpack dev server - run multiple apps on multiple ports
body: <p>Currently I run two apps that sits on the same repo.</p>
  
  <p>The first one runs on <code>/</code> and the other one on <code>port 3000</code> (different HTML files).</p>
  
  <p>I want to make another app that will run on <code>port 5000</code> (with it's own HTML file).</p>
  
  <p>How can I do that?</p>
  
  <p>This is my Webpack config:</p>
  
  <pre><code>   entry: {
  
         mainApp: "./MainApp.js",
         appNumberTwo: "./AppNumberTwo.js"
     }, 
  
    devServer: {
      port: 3000,
      host: '0.0.0.0',
      headers: {
          "Access-Control-Allow-Origin": "*"
      },
      historyApiFallback: {
          index: publicPath + 'app_number_2.html',
      },
      proxy: [{
          target: "http://www.dev.mydomain.com"
      }]
  },
  </code></pre>
