If you want to use multiple environment like .env.development .env.production

use dotenv-cli package

add .env.development and .env.production in project root folder

and your package.json

"scripts": {
    "start": "react-app-rewired start",
    "build-dev": "dotenv -e .env.development react-app-rewired build",
    "build-prod": "dotenv -e .env.production react-app-rewired build",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test --env=jsdom",
    "eject": "react-scripts eject"   
},

then build according to environment like

npm run-script build-dev
