Builds and deploys Firebase SQL Connect (aka Firebase Data Connect) backends with PostgreSQL securely. Use when designing schemas with tables and relations, writing authorized queries and mutations, configuring real-time data updates, or generating type-safe SDKs. Use when you need a relational database with Firebase, or when the user mentions SQL Connect or Data Connect.

## Install

```sh
git clone https://github.com/firebase/agent-skills /tmp/agent-skills && ln -s /tmp/agent-skills/skills/firebase-data-connect-basics ~/.claude/skills/firebase-data-connect
```

## From README

Firebase SQL Connect Firebase SQL Connect is a relational database service using Cloud SQL for PostgreSQL with GraphQL schema, auto-generated queries/mutations, and type-safe SDKs. \[!NOTE\] Product Rename: Firebase Data Connect was renamed to Firebase SQL Connect. All instructions, references, and examples in this skill repository referring to "Data Connect" or "Firebase Data Connect" apply to "SQL Connect" and "Firebase SQL Connect" as well. Project Structure Key Tools for Validation Rely on these two mechanisms to ensure project correctness: Review GraphQL Schema: Both user-defined and generated extensions (in .dataconnect/schema/main/). Validate Operations: Run npx -y firebase-tools@latest dataconnect:compile against the schema. Operation Strategies: GraphQL vs. Native SQL Always default to Native GraphQL. Native SQL lacks type safety and bypasses schema-enforced structures.
