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.

Controlled and uncontrolled form components

So far in this book, we have become familiar with components and how they are the building blocks of any React application. When you blend pieces of independently designed components, you get either a UI component or a full-fledged React web application, depending on what you are working on.

The component-driven approach of React is not going to change anytime soon. Building quality UIs for applications is what React does best. You are going to need a high-performant form one way or the other in your career as a developer, and React has you covered with two approaches to building air-tight form components that prevent data loss and improve user experience regarding form interaction.

These two approaches are controlled and uncontrolled form components. Let’s start with controlled form components so that we have a sufficient understanding of how they are implemented and why they are the React-recommended approach to form handling...
