You must need .env file to run app appropriately. Before writing .env file, you must generate following commands in order to convert the json file of firebase service key into base64 because the app does not read service key as json but strings for some future development benefits.
$ cat firebase-adminsdk.json | base64
Then, create .env file as below
ENV=development|staging|production
API_PORT=put the port whatever you want to use
DB_PORT=put the port whatever you want to use
FIREBASE_JSON64=paste base64 strings
