Question 1

How do I deploy only Cloud Functions with Firebase CLI?

Accepted Answer

Use the command 'firebase deploy --only functions' to deploy Cloud Functions specifically. You can also list and manage functions with 'firebase functions:list' and 'firebase functions:delete' for more control.

Question 2

Firebase CLI vs gcloud CLI for managing Firebase projects?

Accepted Answer

Firebase CLI is optimized for Firebase-specific tasks like emulators and Hosting deployment, while gcloud CLI offers broader Google Cloud services integration. For pure Firebase workflows, the Firebase CLI is more streamlined and feature-rich.

Question 3

Can I use Firebase CLI without Node.js installed?

Yes, via the standalone binary distribution by running 'curl -sL firebase.tools | bash', which doesn't require Node.js. However, the npm version may have more frequent updates and full feature support.

First, run 'firebase setup:emulators:firestore' to download the emulator, then use 'firebase emulators:start' to start it along with other emulators. Configuration is handled through firebase.json for custom rules.

Question 5

What's the best way to switch between multiple Firebase projects quickly?

Accepted Answer

Use 'firebase use' to set active projects and manage aliases, or specify the project ID with the '-P' flag in commands. You can also switch accounts per project with 'firebase login:use'.
