title: Deploying React/Redux App on Heroku
body: <p>I want to deploy a <a href="https://github.com/truffle-box/react-auth-box" rel="nofollow noreferrer">react app</a> on Heroku.</p>
  
  <p>I run <code>npm run build</code> which creates a productionized version into the build_webpack folder. I do a <code>git add .</code> on this folder and try to submit but Heroku doesn't recognize the buildpack.</p>
