How do I connect a Firebase project?

Connecting Firebase

1. Go to console.firebase.google.com, click Add project, and follow setup

1. Enable Firestore Database in your project

Get your credentials

Firebase needs two separate credentials:

• Service account — Project Settings → Service accounts → Generate new private key. Server-only, keep secret.

• Web config — Project Settings → General → "Your apps" → copy the web SDK config object. Safe to expose to the browser.

Environment variables

\\\env NEXT_PUBLIC_DB_TYPE=firebase NEXT_DB_FIREBASE_SERVICE_ACCOUNT={"type":"service_account", ...} NEXT_PUBLIC_FIREBASE_CONFIG={"apiKey":"...", ...} NEXT_PUBLIC_FIREBASE_STORAGE_URL=your-project.appspot.com \\\ Underpeaks uses the Firebase Admin SDK, not the client SDK. Firestore free tier (Spark) allows 50k reads / 20k writes per day. Firebase doesn''t support SQL-style joins — relational queries are handled at the application layer.
