How should I configure create-react-app to serve app from subdirectory?

Question

I have classic web application rendered on server. I want to create admin panel as single page application in React. I want to server admin panel from https://smyapp.example

Answer 1

For create-react-app v2 and react-router v4, I used the following combo to serve a production (staging, uat, etc) app under "/app":

package.json:

"homepage": "/app"

Then in the app entry point:

 
  {/* other components */}
 

And everything "just works" across both local-dev and deployed environments. HTH!
