FastAPI with Pydantic V2 enables building async Python APIs through type-hinted endpoints, V2 field validators, and automatic OpenAPI documentation. Use async/await for I/O operations, Pydantic's model_config for schema control, and Annotated for dependency injection to enforce type safety end-to-end.
Yes. Async SQLAlchemy patterns integrate with FastAPI by using async sessions and awaiting database queries within async route handlers. This prevents blocking I/O and maintains the non-blocking advantages of async frameworks.
Implement JWT/OAuth2 authorization in FastAPI by validating tokens in dependency functions, encoding credentials with JWT libraries, and protecting routes with security schemes. FastAPI's security utilities simplify token validation and automatic OpenAPI documentation of auth requirements.
Pydantic V2 replaces validators with field_validator and model_validator decorators, uses model_config for settings, and improves serialization control. FastAPI endpoints must use V2 syntax to leverage modern validation and avoid deprecated patterns.
Yes. FastAPI provides built-in WebSocket support for real-time bidirectional communication. You define WebSocket endpoints similarly to HTTP routes, using async context managers and message handling within the same dependency injection framework.
