FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints. It is designed to be easy to use, while also being fast and efficient. Some key features and advantages of FastAPI include:

• Fast and High Performance: FastAPI is built on top of Starlette and Pydantic, utilizing asynchronous programming to achieve high performance. It is one of the fastest web frameworks available for Python.

• Automatic API Documentation: FastAPI automatically generates interactive API documentation (using Swagger UI and ReDoc) based on the Python type hints, making it easy for developers to understand, test, and consume the API.

• Type Hints and Data Validation: FastAPI uses Python type hints for request and response data, enabling automatic data validation. This helps catch errors early in the development process and improves the overall reliability of the API.

• Dependency Injection System: FastAPI provides a built-in dependency injection system, making it easy to manage and inject dependencies into route functions.

• Security: It comes with built-in security features, such as OAuth and JWT token support, which simplifies the implementation of secure authentication and authorization in APIs.

• WebSocket Support: FastAPI supports WebSocket communication, allowing real-time bidirectional communication between clients and the server.

• Synchronous and Asynchronous Code: FastAPI supports both synchronous and asynchronous code, making it flexible for different use cases and allowing developers to leverage the benefits of asynchronous programming when needed.

• Easy Integration with Other Libraries: FastAPI seamlessly integrates with other popular Python libraries and frameworks, such as SQLAlchemy, Tortoise-ORM, and others.

• Automatic Generation of API Client Code: Using the generated OpenAPI documentation, FastAPI can automatically generate API client code in multiple programming languages, reducing the effort required to consume the API.

• Active Development and Community Support: FastAPI is actively developed and has a growing community. The framework is well-documented, and its community actively contributes to its improvement.

Overall, FastAPI is a modern and powerful web framework that prioritizes developer productivity, type safety, and high performance, making it an excellent choice for building APIs with Python.

Uvicorn is an ASGI (Asynchronous Server Gateway Interface) server that is specifically designed to run ASGI applications, such as those built with the FastAPI web framework. ASGI is a specification for asynchronous web servers and applications in Python, providing a standard interface between web servers and Python web applications or frameworks.
