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.

How JSX abstracts JavaScript

Nowadays, coding React applications without JSX is not recommended, though it is possible. For instance, you can write a React.createElement(component, props, ...children) function to describe a UI.

However, you can easily describe a button UI in JSX with the following code:

<Button color="wine">    Click a Wine Button
</Button>

Writing the preceding code without JSX would require you to describe a button UI with the following code:

React.createElement(Button,
    {color: 'wine'},
    ' Click a Wine Button')

Doing this in a large React project could lead to multiple issues, such as having to deal with more bugs in your code base and facing a steeper learning curve to become a code-savvy developer who could function optimally at writing this low-level code to describe a UI. However, with very little to disagree on, you would agree that JSX...
