FastAPI Tutorial Part 2: HTTP vs WebSocket, Your First GET API
🚀 FastAPI Tutorial Part 2: Master APIs, REST, and Build Your First GET Endpoint! 🚀
In this second part of our FastAPI tutorial series, we dive deep into the core concepts of API design and development using Python's FastAPI framework. You'll learn when to choose between HTTP and WebSocket APIs, the different types of HTTP APIs, understand RESTful principles, and finally, build your first GET API using FastAPI!
*What You'll Learn:*
*HTTP vs. WebSocket APIs:* Understand the key differences and when to use each protocol for optimal performance and real-time capabilities. We'll cover the strengths and weaknesses of both.
*Types of HTTP APIs:* Explore various API architectures you can implement with HTTP (not just REST!).
*REST API Methods Explained:* A clear, concise explanation of common REST methods (GET, POST, PUT, DELETE, PATCH) and their purposes. We'll focus on best practices.
*Building a GET API with FastAPI:* Hands-on coding! We'll write Python code using FastAPI to create a functional GET endpoint. You'll learn how to:
Define routes
Handle requests
Return data in JSON format
Use path parameters
Use query parameters
*Step-by-step guide to create GET API using python and fastAPI*
*Why FastAPI?*
FastAPI is a modern, high-performance web framework for building APIs with Python 3.7+ based on standard Python type hints. It's incredibly fast, easy to learn, and production-ready.
