Introduced 2026-03-09 · score 0.90

HOW TO USE IT

When you have a Firebase project set up to use SQL Connect, run `firebase init dataconnect:resolver` to scaffold a custom resolver, then define its schema and implement the resolver logic in Cloud Functions.

WHY THIS HELPS

Configure custom resolvers for a Firebase Data Connect project.

REQUIREMENTS AND LIMITATIONS

• Version: v15.9.0
• Prerequisite: Firebase CLI v15.9.0 or higher and Firebase Functions SDK v7.1.0 or higher.
• Prerequisite: A project already set up to use SQL Connect; custom resolver logic is implemented with Cloud Functions.
