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.

The first step in sending data to a database is to ensure there is a connection between the Flask app and the database. This involves installing the required libraries and ensuring that you work in a virtual environment to contain your installation and prevent unexpected occurrences, due to the interference of other libraries.

Let’s make use of the bizza/backend directory created in the Setting up the development environment with Flask section of Chapter 1. You can create one if you haven’t already. Install and activate the virtual environment.

To create a virtual environment, open your project root directory in a terminal and add the following...
