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 subtle difference between the elements of React forms and those of normal HTML forms is due to the unique way React handles the internal state of forms. The HTML DOM manages the internal states of native HTML form elements in a browser DOM way. On the other hand, React handles form elements through its components’ state.

So, what is this state all about? The state we are talking about is an object that holds user inputs before form submission. Form elements have an internal state that prevents data loss before you submit user input across the processing channel.

Having laid down the background for the internal state management of form elements, let’s quickly...
