create react app not picking up .env files?

Question

I am using create react app to bootstrap my app.

I have added two .env files .env.development and .env.production in the root.

Answer 1

As of latest react-scripts (3.2.0) it's a simple as putting say

PORT=4000
BROWSER=none

in your .env or .env.development file (..etc) which is supposed to be in the root folder.

It will NOT work with then REACT_APP prefix (the docs are outdated I guess) and it does NOT require any extra npm packages (react-scripts already includes dotenv 6.2.0)
