Implementing a REST API in a Flask application

Flask, as a popular Python web framework, provides developers with a flexible and lightweight solution for building web applications. With Flask, you can easily create and manage RESTful APIs. The process of implementing a REST API in a Flask application is simple.

Implementing a REST API in a Flask application involves defining API endpoints, request handlers, and data models, and possibly connecting to a database. In this section, we are going to design a REST API service using Flask that a React frontend application can consume.

We will follow a simple process of defining the resources expected in the Bizza application, following which we will define the URLs (endpoints) that would be used to access the resources. In addition, we will use Flask’s routing system to map each endpoint to a specific function in the application.

Each function should handle the HTTP request, interact with the database (if necessary), and return...
