I'm a hobby developer and have worked with Firebase a bit, but never on a production level.
One thing I never really quite understood is where do I keep my firebase credentials? I always keep the credentials in an env file, and have a firebase.js file at the root of my project in which I initialize my project, but essentially, my credentials are completely exposed to the client.
Specifically, I am now working on a React Native app (Expo), and would love to know the correct approach for working with the SECRET environment variables for production.
Aside from the Firebase credentials, I also have a few other variables that I would like to keep secret.
