My question is similar to the question Relative path in index.html after build, except that it happens in my development environment, and the index.html has:
http://dev.local:8100/app/index.html (in react public folder)
  <script src="/static/js/bundle.js"></script><script src="/static/js/vendors~main.chunk.js"></script><script src="/static/js/main.chunk.js"></script></body>
I can make it work if I build react, and that's how it work on production. But for development it is better if I can make it work just using react-scripts start (yarn/npm).
I have tried changing homepage in package.json and start_url in manifest.json, but couldn't get it to work.
I need the index.html to be:
  <script src="static/js/bundle.js"></script><script src="static/js/vendors~main.chunk.js"></script><script src="static/js/main.chunk.js"></script></body>
Any suggestions?
