Firebase Data Connect

This skill helps Claude build Firebase backends with PostgreSQL through GraphQL schemas, handling everything from table definitions to type-safe SDK generation across Web, iOS, Android, and Flutter. It defaults to GraphQL operations for type safety but can drop into raw SQL when you need PostgreSQL-specific features like PostGIS or window functions. The workflow is structured around schema definition, authorized operations with row-level security, and real-time subscriptions. Particularly solid on the security model since Firebase Data Connect (now SQL Connect) is secure by default, requiring explicit auth directives. If you're tired of managing your own Postgres infrastructure or want Firebase Auth integration with relational data, this handles the boilerplate and generates client code that actually knows your schema.
