FAQ

How do I define my data model in Firebase Data Connect?

You define your data model using GraphQL schema syntax in the `schema/schema.gql` file. You can define GraphQL types, tables, and relationships using directives like `@table`, `@col`, and `@ref` to structure your data effectively.

What platforms are supported for SDK generation?

Firebase Data Connect supports SDK generation for Android (Kotlin), iOS (Swift), Web (TypeScript), and Flutter (Dart) applications.

Can I perform complex queries like filtering and pagination?

Yes, Firebase Data Connect allows you to create complex queries with filters (e.g., `where`), ordering (e.g., `orderBy`), and pagination (e.g., `limit`, `offset`). These queries are auto-generated into the underlying SQL.

Is Firebase Data Connect compatible with Firebase emulators?

Yes, you can run Firebase Data Connect locally using Firebase emulators. This allows you to develop and test your application in an offline environment before deploying it to production.

Are there any requirements for securing my Firebase Data Connect app?

Yes, Firebase Data Connect includes built-in authorization features. You can use the `@auth` directive for different access levels like PUBLIC or USER, and row-level security can be enforced using directives such as `@check` and `@redact`.
