Fast API

Fast API:

FastAPI is a modern, high-performance web framework for building APIs with Python. It is built on top of Starlette, an asynchronous web framework, and leverages Python 3.7+ features such as type hints and async/await syntax.

Here are some key features and benefits of FastAPI:

Fast: FastAPI is designed for high-performance applications. It achieves this by using asynchronous programming, which allows it to handle a large number of requests concurrently without blocking.

Easy to use: FastAPI is built with a focus on developer productivity and ease of use. It provides intuitive and declarative syntax, making it straightforward to define API endpoints, request/response models, and input validation rules.

Type hints and automatic documentation: FastAPI leverages Python’s type hinting system to provide powerful automatic data validation and documentation generation. It can automatically generate interactive API documentation (based on the OpenAPI standard) that allows developers to explore and test the API endpoints easily.

OAuth2 and JWT support: FastAPI has built-in support for OAuth2 authentication and JWT (JSON Web Tokens). It provides decorators and authentication middleware to secure your API endpoints.

WebSocket support: FastAPI supports WebSocket communication, allowing you to build real-time applications and push data from the server to the client.

Integrations: FastAPI seamlessly integrates with other popular Python libraries and tools such as Pydantic (for data validation and serialization), SQLAlchemy (for database integration), and Docker (for containerization).

Overall, FastAPI offers a powerful and efficient framework for building APIs with Python, combining high performance with developer-friendly features. It has gained significant popularity in the Python community due to its speed, ease of use, and modern features.
