Overview of this book

Developing an interactive, efficient, and fast enterprise web application requires both the right approach and tooling. If you are a web developer looking for a way to tap the power of React’s reusable UI components and the simplicity of Flask for backend development to develop production-ready, scalable web apps in Python, then this book is for you. Starting with an introduction to React, a JavaScript library for building highly interactive and reusable user interfaces, you’ll progress to data modeling for the web using SQLAlchemy and PostgreSQL, and then get to grips with Restful API development. This book will aid you in identifying your app users and managing access to your web application. You’ll also explore modular architectural design for Flask-based web applications and master error-handling techniques. Before you deploy your web app on AWS, this book will show you how to integrate unit testing best practices to ensure code reliability and functionality, making your apps not only efficient and fast but also robust and dependable. By the end of this book, you’ll have acquired deep knowledge of the Flask and React technology stacks, which will help you undertake web application development with confidence.

Configuring the React frontend for API consumption

In this section, you will configure the frontend React app to communicate with the backend Flask server by setting up a proxy in React to consume the API from the Flask server.

In order to configure the React proxy for API consumption, you will need to update the proxy field in the package.json file of the frontend React app. The proxy field allows you to specify a URL that will be used as the base for all API requests made from the React app.

Let’s update the package.json file:

  1. Open the package.json file in the project directory using a text editor, and then add a proxy field to the package.json file and set it to the URL of your Flask server:
    {  "name": "bizza",  "version": "0.1.0",  "proxy": "http://localhost:5000"}
  2. Next, you will need to make HTTP requests to the Flask server from the React frontend. We will use the...
