The core architecture revolves around three components: Services (API endpoints), Schemas (GraphQL data model definitions), and Connectors (fine-grained access control per application or role). A practical setup walkthrough covers installing the Firebase CLI, initializing a project, defining a schema and connector, generating a typed SDK, and running a local emulator. Code examples show how to define a User type, write queries and mutations with auth levels, and call the generated SDK from a TypeScript client. ## Full article daily.dev links to this article rather than hosting it.
