Getting Started with FastAPI
FastAPI is a modern, high-performance web framework for building APIs with Python 3.10+ based on standard Python type hints.
Learning Outcomes
By the end of this tutorial, you will be able to:
- •Set up an isolated Python virtual environment and install FastAPI with Uvicorn.
- •Create and run high-performance asynchronous API endpoints.
- •Use path parameters and query parameters with automatic type validation.
- •Leverage automatic interactive documentation via Swagger UI and ReDoc.
- •Understand how Pydantic guarantees request and response data integrity.
FastAPI is built on top of Starlette (for web routing and async support) and Pydantic (for data validation and schema generation).
