title: Using WebWoker with create-react-app and typescript
body: <p>I'm having the project using <code>create-react-app</code> and <code>typescript</code></p>
  
  <p>I would like to enable <code>WebWorker</code> to do some expensive tasks. But I have not found any solutions to enable it.</p>
  
  <p>I have looked through some libraries:</p>
  
  <ul>
  <li><a href="https://github.com/developit/workerize-loader" rel="noreferrer">https://github.com/developit/workerize-loader</a></li>
  </ul>
  
  <p>Do you have any ideas?</p>
  
  <p>Thanks in advance!</p>
