Demo

You may run the following commands to test out this project:

1. Build

npx react-inject-env build npm run build

2. Inject

npx react-inject-env inject -d ./build -o ./build-black

3. Serve

npx http-server build-black 

4. Change variables and re-serve

Try editing the .env file in the root folder and re-run steps #2 and steps #3

.env

REACT_APP_COLOR = purple
REACT_APP_LOGO_URL =./logo512.png
REACT_APP_MAIN_TEXT = Insert Text here
REACT_APP_LINK_URL = https://my.link

npx react-inject-env inject -d ./build -o ./build-purple

npx http-server build-purple

5. Overwriting variables from command line

If an env variable is passed through the command line, it will overwrite variables in the .env file.

REACT_APP_COLOR=blue npx react-inject-env inject -d ./build -o ./build-blue

// the app will now have a blue background
npx http-server build-blue
