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.

Using the Flask debugger

Flask as a lightweight Python web framework is widely used for building web applications. One of the out-of-the-box benefits of using Flask is its built-in debugger, which provides a powerful tool for identifying and fixing errors in your application.

When an error occurs in your Flask application, the debugger will automatically be activated. The debugger will provide detailed information about the error, including a stack trace, source code context, and any variables that were in scope at the time the error occurred. This information is golden for determining the root cause of the error and possible ideas for fixing it.

The Flask debugger also provides some interactive tools that can be used to inspect the state of your application and understand what is happening. For instance, you can evaluate expressions and examine the values of variables. You can also set breakpoints in your code, and step through your code line by line to see how it is executed...
