title: How can I use style-loader in react SSR (Server Side Rendering)?
body: <p>As you know, we can easily use style-loader to add our styles to our react project, but the <strong>window</strong> is not available in Server Side Rendering, so how I can use style-loader (or something instead of that in SSR project)?</p>
  
  <p>When I use <em>style-loader</em>, it returns this error as expected:</p>
  
  <pre><code> .../public/server.js:866
          return window &amp;&amp; document &amp;&amp; document.all &amp;&amp; !window.atob;
          ^
  
      ReferenceError: window is not defined
  </code></pre>
