Python FastAPI at a Glance

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. It is easy to use, easy to learn, and provides automatic interactive API documentation with Swagger UI.

Why FastAPI?

FastAPI is gaining popularity among developers due to its high performance, ease of use, and the ability to automatically generate interactive API documentation. It is built on top of Starlette for the web parts and Pydantic for the data parts, making it a powerful and efficient web framework.

Pros

• FastAPI is fast and efficient, making it ideal for building high-performance APIs.
• It is easy to use and learn, especially for developers familiar with Python.
• Automatic interactive API documentation with Swagger UI makes it easy to document and test APIs.

Cons

• FastAPI is relatively new compared to other Python web frameworks, so it may have fewer resources and community support.
• It requires Python 3.6 or later, which may be a limitation for some projects.

CRUD Operations with FastAPI

Here is a quick overview of how to perform CRUD (Create, Read, Update, Delete) operations with FastAPI:

Create

To create a new resource, you can define a route using the @app.post decorator and specify the request body using Pydantic models.

Read

To retrieve a resource, you can define a route using the @app.get decorator and return the resource as a response.

Update

To update an existing resource, you can define a route using the @app.put decorator and specify the resource to update in the request body.

Delete

To delete a resource, you can define a route using the @app.delete decorator and specify the resource to delete as a parameter.

Overall, FastAPI is a powerful and efficient web framework for building APIs with Python. Its high performance, ease of use, and automatic interactive API documentation make it a great choice for developers looking to create fast and reliable APIs.
