title: How do I add a Babel plugin to a create-react-app project?
body: <p>I'm following LearnCode.academy video tutorial and on video #7 at some point the tutor/presenter add the following code</p>
  
  <pre><code>@connect((store) =&gt; {
      return {user: store.user.user, tweets: store.tweers.tweers}
  })
  </code></pre>
  
  <p>I understand I need to configure Webpack by adding <code>babel-plugin-transform-decorators-legacy</code> but <code>create-react-app</code> is not showing any of the configuration files. What is the solution here?</p>
