title: Unable to import (require) css, less, sass file on react component when using express server
body: <p>I'm importing less or css file to my react component and it is working fine on my following example project:
  <a href="https://github.com/digz6666/webpack-loader-test" rel="nofollow noreferrer">https://github.com/digz6666/webpack-loader-test</a></p>
  
  <p>But when I use express server to implement SSR I no longer can import less file to my react component. It is only working on index.js entry file.
  It throws following exception:</p>
  
  <pre><code>[1] Error: Module parse failed: Unexpected token (2:0)
  [1] You may need an appropriate loader to handle this file type.
  [1] | // @import '~antd/dist/antd.css';
  [1] &gt; .trigger {
  [1] |   font-size: 18px;
  [1] |   line-height: 64px;
  [1]     at eval (webpack:///./src/client/layout/baseLayout.less?:1:7)
  </code></pre>
  
  <p>Here's the example project that I use SSR:
  <a href="https://github.com/digz6666/webpack-loader-test/tree/ssr" rel="nofollow noreferrer">https://github.com/digz6666/webpack-loader-test/tree/ssr</a></p>
  
  <p>Please uncomment styles in following file, npm install and npm start to test:</p>
  
  <pre><code>/src/client/layout/baseLayout.less
  </code></pre>
