fastapi-repository-pattern

Build a generic repository class integrating async SQLAlchemy 2.0 with FastAPI, instantiating it with a SQLAlchemy model and AsyncSession to handle type-safe CRUD operations across multiple models.

The repository pattern centralizes CRUD operations into a reusable class, separating database access from business logic. In FastAPI, this ensures consistent data access and testable database logic.

Yes, the generic repository pattern supports async SQLAlchemy 2.0 integration, enabling scalable FastAPI APIs with type-safe methods for get, list, create, update, and delete operations on your models.

Separate database access logic by moving CRUD operations into a generic repository class, keeping FastAPI services focused on business logic while the repository handles SQLAlchemy queries and data access.

A type-safe FastAPI repository provides methods for get, get_by, list, count, create, create_multi, update, delete, and exists, all operating on SQLAlchemy models and Pydantic schemas.

Yes, the generic repository pattern applies to projects requiring consistent data access across multiple models by instantiating the repository class with different SQLAlchemy models and an AsyncSession.
