FastAPI Tutorial

Welcome to the complete FastAPI tutorial! This tutorial series will take you from zero to mastering FastAPI, a modern and fast Python web framework.

🚀 What is FastAPI?

FastAPI is a modern, fast (high-performance) web framework for building APIs based on standard Python type hints. It features:

• Fast: Very high performance, on par with NodeJS and Go
• Fast to code: Increase development speed by about 200% to 300%
• Fewer bugs: Reduce about 40% of human-induced errors
• Intuitive: Great editor support with auto-completion
• Easy: Designed to be easy to use and learn, reducing time reading documentation
• Short: Minimize code duplication, achieve rich functionality through parameter declarations
• Robust: Production-ready code with automatic interactive documentation
• Standards-based: Based on and fully compatible with open API standards: OpenAPI and JSON Schema
