title: How to add import shortcuts - alias
body: <p>I've created a brand new react app</p>
  
  <pre><code>create-react-app demo 
  </code></pre>
  
  <p>I need to create alias for some directories/components like:</p>
  
  <pre><code>import { Header } from '@uicomponents' 
  </code></pre>
  
  <p>Where <code>@uicomponents</code>  is shortcut for the path '<code>src/hello/this/is/the/path/to/ui/components</code> '</p>
  
  <p>All online tutorials telling that I can use alias imports using <code>resolve.alias</code>, but I'm wondering how to do this with brand-new react app?</p>
  
  <p>Theres is no .babelrc  or webpack.config.js  files.</p>
  
  <p>Any help please?</p>
