Based on common Python-type hints, FastAPI is a fast web framework for developing APIs using Python 3.7+. It facilitates the speedy and effective creation of apps by developers. FastAPI, built on top of the Starlette web server, has features like automated data validation, error management, and interactive API documents that make it simpler to create online apps.
FastAPI is a cutting-edge web framework for creating Python RESTful APIs. Due to its simplicity, speed, and resilience, it has rapidly been a favorite among developers since its initial release in 2018. For data validation, serialization, and deserialization, the FastAPI uses Pydantic and type hints. For APIs created with it, it also automatically creates OpenAPI documentation.
FastAPI is an attractive option for production situations since it embraces asynchronous programming and runs on Gunicorn and ASGI servers like Unicorn and Hypercorn. In addition, since the project's inception, editor support has been addressed to increase developer friendliness.
Thanks to Starlette and Pydantic, it provides extremely high performance comparable to NodeJS and Go.
FastAPI is just what its name implies—fast. One of the quickest Python frameworks currently available is said to be this one.
FastAPI was created to be simple to use and understand. In addition, it provides excellent documentation and editing support.
To save you time reading documentation, it is easy to use and understand.
It integrates nicely with JSON schema, OpenAPI (formerly Swagger), and other open standards for APIS.
You can write code suitable for production using automated interactive documentation.
It lessens the likelihood of mistakes brought on by people. It cuts down on induced bugs by around 40%.
FastAPI is relatively easy to use, and its instructions are well-written and simple. Tech behemoths like Microsoft, Netflix, and Uber employ FastAPI.
For creating contemporary interfaces for applications using Python 3.6 and above, FastAPI is a quick and lightweight web framework.
The data validation function of FastAPI is useful while creating and fixing code that communicates with an API. The cherry on top is the built-in documentation support that is listed with all of the endpoints. It also has better runtime performance.
