About
Firebase Admin API Skill
Overview
Firebase Admin SDK allows privileged server environments to interact with Firestore, Auth, and Cloud Messaging.
Installation
npm install firebase-admin
pip install firebase-adminAuthentication
Authenticate using a Google Cloud Service Account key JSON file or Application Default Credentials (ADC).
Core Concepts
- Firestore: NoSQL document database.
- Custom Tokens: JWTs minted on the server to log users into the client SDK.
- FCM: Firebase Cloud Messaging for push notifications.
Common Workflows
- Initialize
initializeApp({ credential: cert(serviceAccount) }). - Access Firestore:
getFirestore(). - Perform operations bypassing security rules.
Error Handling
Catch FirebaseError. Error codes match RPC statuses (e.g., not-found, already-exists).
Security
Service accounts have absolute God-mode access. Never deploy an Admin SDK service account key to a client application.
Rate Limits
Firestore allows 10,000 writes per second per database. Batch operations are limited to 500 documents per batch.
Best Practices
Use batch() for multiple writes to ensure atomicity. Use runTransaction() when a write depends on the current value of a document.
Troubleshooting
If initialized multiple times, the SDK throws a 'default app already exists' error. Check getApps().length before initializing.
