FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.8+ based on standard Python type hints.

The key features are:
→ Fast: Very high performance, on par with NodeJS and Go (thanks to Starlette and Pydantic). One of the fastest Python frameworks available.
→ Fast to code: Increase the speed to develop features by about 200% to 300%.
→ Fewer bugs: Reduce about 40% of human (developer) induced errors.
→ Intuitive: Great editor support. Completion everywhere. Less time debugging.
→ Easy: Designed to be easy to use and learn. Less time reading docs.
→ Short: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs.
→ Robust: Get production-ready code. With automatic interactive documentation.
→ Standards-based: Based on (and fully compatible with) the open standards for APIs: OpenAPI (previously known as Swagger) and JSON Schema.
→ Support various API's :- Rest, GraphQL(using strawberry), websockets.
