I'm attempting to build a environment variable: PUBLIC_URL for a react app out of two pre-existing ENV vars DOMAIN and URL_PREFIX. I'm hoping to do so right before running the 'react-scripts build' command within an npm script.
I'm using a .env-cmdrc.json file for storing multiple environments variables all in one place. I'm currently building the var and calling the command like so.
env-cmd -e shared,staging --use-shell "export PUBLIC_URL=https://$DOMAIN/$URL_PREFIX && react-scripts build"
I'm running the command from the 'client' folder which contains both .env-cmdrc.json and package.json. It results in the following error indicating the variables were never expanded.
throw new ERR_INVALID_URL(input);
^
TypeError [ERR_INVALID_URL]: Invalid URL: https:///

}
the variables $DOMAIN and $URL_PREFIX are consumed just fine by the react-scripts build command: env-cmd -e shared,staging react-scripts build or just printenv DOMAIN , but they do not appear in other commands such as printing out in echo $DOMAIN
I think I'm missing something when it comes to passing environments between commands but I can't figure out why env-cmd -e shared,staging printenv DOMAIN would work, but env-cmd -e shared,staging echo $DOMAIN wouldn't.
