To structure a FastAPI project with async database sessions, use a layered architecture that separates api, core, models, schemas, services, and repositories. This enforces clean dependency injection using Depends and manages async database access through lifespan startup and shutdown handlers.

The best way to add JWT authentication to a FastAPI application is by wiring a get_current_user dependency. This approach integrates seamlessly with the dependency injection system to provide consistent authorization checks and secure route access across your API endpoints.

To set up pytest for testing async FastAPI endpoints, configure an async test client and apply database dependency overrides. This allows your test suite to interact with the API and database asynchronously, ensuring your async route handlers are properly validated.

Yes, you can use the repository pattern for CRUD operations in FastAPI to achieve a clean separation of concerns. By isolating database access logic in repositories and business logic in services, you maintain a scalable and testable layered architecture for your REST API.

FastAPI supports an async lifespan context manager for handling database connection management. This pattern allows you to safely initialize database sessions during application startup and gracefully close connections during shutdown, ensuring reliable async database access.
