Question 1

How to deploy Firebase Hosting with GitHub Actions using firebase-action?

Accepted Answer

Use the action in a workflow step with args like 'deploy --only hosting', and set env variables such as GCP_SA_KEY or FIREBASE_TOKEN for authentication. Ensure your firebase.json is in the correct path, and build artifacts are available if needed.

Question 2

What's the difference between firebase-action and setup-firebase?

Accepted Answer

firebase-action is a Docker-based wrapper focused on simplicity, while setup-firebase is an early rewrite that allows choosing Node.js/Java versions and running multiple commands in one step, offering more flexibility but less maturity.

Question 3

How to set up authentication with a service account key in firebase-action?

Accepted Answer

Create a Google Cloud service account key with JSON format, encode it if needed, and set it as the GCP_SA_KEY secret in GitHub. Assign required IAM roles based on the Firebase services you're using, as listed in the README.

Question 4

Can I use firebase-action for multiple Firebase projects in a single workflow?

Accepted Answer

Yes, by specifying different PROJECT_ID inputs in separate steps or using .firebaserc configurations. However, you'll need to manage authentication for each project, which can complicate secret handling.

Question 5

How to handle Firebase Functions configuration in GitHub Actions with this action?

Accepted Answer

Use the CONFIG_VALUES input to set configuration values directly, like 'stripe.secret_key=SECRET_KEY', avoiding manual firebase functions:config:set commands. Ensure secrets are stored in GitHub and passed securely.

Question 6

Is firebase-action compatible with Firebase Emulator Suite for testing?

Accepted Answer

No, the action is designed for deployment and management commands, not for local emulation. You'd need separate steps or actions to run the Firebase Emulator in CI/CD, as this focuses on live Firebase services.
