Following our first API with FastAPI in Creating Your First Web API with FastAPI, this article explores API Routing and HTTP Verbs for RESTful Endpoints. We'll learn how to structure our API with different routes and how to use the correct HTTP methods for each action.
We've successfully created a simple Flask application that can serve a response from a single URL. But a real website has many pages: an about page, a contact page, user profiles, and so on. The system that maps URLs to the Python functions that handle them is called routing.
With our environment set up, it's time to write our very first web application with Flask. The traditional starting point for any new programming endeavor is the "Hello, World!" application. We'll create a simple web server that, when accessed, returns that classic phrase to the user's browser.
