FastAPI Modern Development

FastAPI is the standard for modern Python APIs, offering high performance (comparable to Go/Node.js) and automatic documentation.

Type Safety (Pydantic)

• Schemas: Use Pydantic models for request/response validation and serialization.
• Automatic Docs: OpenAPI (Swagger) and Redoc are generated automatically based on type hints.

Asynchronous Support

• async def: High concurrency with Python's asyncio loop.
• Dependency Injection: A powerful system for managing database sessions, auth, and logic.

Best Practices

• Strict Typing: Use Python 3.10+ union types (int | None) and Annotated for cleaner dependencies.
• Error Handling: Use HTTPException with consistent JSON structures.
