Explanation
Introduction
FastAPI is a web framework for building APIs in Python 3.6+ based on standard Python type hints. It offers high performance, easy learning curves, and features suitable for production. FastAPI allows developers to create APIs quickly and efficiently with a focus on performance.
What It Is
FastAPI is an open-source web framework for building APIs with Python, distinguished by its speed and ease of use. It leverages Python type hints for parameter validation, serialization, and documentation generation.
What It Is Used For
FastAPI is primarily used for developing backend services, REST APIs, and microservices, making it suitable for both small and large-scale applications.
Key Points
- FastAPI ensures high performance equivalent to Node.js and Go.
- It has automatic interactive API documentation generation.
- Strong support for asynchronous programming with async and await.
Basic Examples
- To create a simple FastAPI application, you can define a basic endpoint using the FastAPI class.
- app = FastAPI()
- @app.get('/')
