Environment Variables

[camstuart]

Hi,

I'm using the react version of prime ui.

My understanding of env vars with create react app is to use the prefix: REACT_APP_

But if I modify my start script to include REACT_APP_MY_VAR=foo and then console log process.env it's undefined

My goal is you use env vars to set the address of the backend API for dev and production. What's the correct approach here?
