Pros and cons of FastAPI?

Advantages of FastAPI:

• Very high performance thanks to ASGI and Starlette.
• Simplicity and conciseness of code, thanks to Python type hints.
• Automatic generation of API documentation (Swagger UI and ReDoc).
• Built-in data validation with Pydantic.
• Support for asynchronous programming out of the box.
• Good integration with OAuth2, JWT, and other authentication systems.

Disadvantages of FastAPI:

• Relatively new library, smaller community compared to Django or Flask.
• Difficulties with debugging asynchronous code may arise for beginners.
• For complex projects, additional configuration and integration with other tools may be required.
• Some libraries and tools may not fully support asynchronous operations.

FastAPI is excellent for creating fast and modern APIs, especially when performance and development convenience are important.
