What is Firestore?

Firestore is Google Cloud's flexible, scalable NoSQL document database designed for mobile, web, and server applications. In Frontend Accelerator, Firestore is integrated through an adapter pattern, allowing you flexibility to switch to other database solutions.

How Firestore works in Frontend Accelerator:

The database adapter provides a unified interface for Firestore operations. When configured with Firestore, the adapter translates standard CRUD operations into Firestore queries.

Example configuration:

// Configure env variable
AUTH_FIREBASE_PROJECT_ID="project-name"
AUTH_FIREBASE_CLIENT_EMAIL="project-email"
AUTH_FIREBASE_PRIVATE_KEY="secret"

const dbAdapter = new Database();

// Create document with auto-generated ID
await dbAdapter.createUser({
  email: 'user@example.com',
  displayName: 'John Doe',
  createdAt: new Date()
});

Key features:

• Scalability: Automatic scaling with Google Cloud infrastructure
• Security rules: Declarative access control at the database level
• Cloud functions: Trigger backend logic on data changes
• Multi-region: Global data replication for low latency

Adapter pattern benefits:

• Database agnostic: Switch from Firestore to MongoDB or others easily
• Consistent API: Same interface regardless of underlying database
• Real-time abstraction: Abstract away Firestore-specific real-time listeners
• Testing support: Use mock adapters for unit testing
• Type safety: Full TypeScript support with proper typing

AI-friendly: The Firestore adapter in Frontend Accelerator uses a standardized interface that AI can easily understand and implement. AI assistants can help structure collections, write security rules, optimize queries, without deep Firestore expertise.
