title: Deploy create-react-app build version to Heroku
body: <p>I'm working with a create-react-app generated app which I'm deploying to Heroku. I would like to test out the production version <code>npm run build</code> in an actual server.</p>
  
  <p>Is it possible to serve the build version instead of the development version to heroku? It's okay if I can no longer have the dev version up in that heroku instance.</p>
  
  <p>If possible, <em>how can I do so</em>, I have been searching up and nothing comes up</p>
