Pydantic Schemas

Use separate schemas for input/output
Use Field() for validation
Use model_validator for complex validation
Use Config for schema settings

Dependency Injection

Use Depends() for dependencies
Create reusable dependencies
Use yield for cleanup logic
Cache expensive dependencies

Async

Use async def for I/O operations
Use httpx for async HTTP
Use databases/SQLAlchemy async
Avoid blocking in async context

Performance

Use response_model for serialization
Enable response caching
Use background tasks
Stream large responses
Use connection pooling
