Deployment Safety

When to use this skill

• •Before running firebase deploy.
• •When preparing a release candidate.
• •When writing deployment scripts / CI pipelines.

How to use it

1. •Pre-Flight Checks:
   • •Have all rules been audited (firestore-rules-audit)?
   • •Have all functions been locally emulated and tested?
   • •Are there any breaking schema changes?
2. •Rolling Strategy:
   • •Deploy Rules & Indexes first.
   • •Deploy Functions.
   • •Deploy Front-end (if applicable / hosting).
3. •Safe Function Updates:
   • •When updating a function that handles events, ensure the new version is compatible with existing in-flight events.
   • •Avoid renaming functions—Eventarc triggers might break. Create new, deprecate old.
4. •Rollback Plan:
   • •Ensure we have the previous version's artifacts or git commit hash ready.
   • •If a bad deployment occurs, know the sequence to revert (revert code, redeploy).
