title: Webpack Sequential Multiple Configs?
body: <p>I have a single file <code>webpack.dev.js</code> and within it I have 2 standard build configs.  </p>
  
  <pre><code>const buildA = {};
  const buildB = {};
  
  module.exports = [buildA, buildB];
  </code></pre>
  
  <p>This is sweet, everything works.  The problem is however that <code>buildB</code> expects <code>buildA</code> to complete and the builds appear to occur in parallel.  So I get an error. </p>
  
  <p>Is there a way to achieve sequential builds when using this format?  Otherwise, how could I achieve something similar by another means?</p>
  
  <p>I am using <code>webpack-dev-server</code> which appears to only take a single configuration and that is why I am down this path of multiple configurations exported</p>
