Firebase Rules: Production Security Baseline and Deployment
Apply strict Firestore and Storage rules with explicit allowlists to prevent accidental client-side access to sensitive collections.
What this guide helps you do
Consistent, production-safe data access boundaries across client and server surfaces.
Recommended sequence
- Keep Firebase rules files versioned in repo: firestore.rules, storage.rules, and database.rules.json.
- Use write-only client collections for analytics/unsubscribe and deny-by-default for sensitive collections.
- Route privileged mutations through authenticated server APIs that use Firebase Admin SDK.
- Deploy rules as part of release workflow, not ad-hoc console edits.
- Re-audit rules after adding any new client SDK read/write path.
Common mistakes to avoid
- Leaving temporary test-mode reads/writes enabled in production.
- Adding a new client Firestore call without updating the rules allowlist.
- Exposing profile/admin collections directly to client reads when server routes already exist.
