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.

Handling exceptions

Handling exceptions with unit testing is a software development technique that involves testing how a piece of code handles different types of exceptions that may occur during runtime. Exceptions can be triggered by a variety of factors, such as invalid input, unexpected input, or issues with the environment in which the code is running.

Unit testing is the practice of writing small, automated tests to ensure that individual units of code are working as expected. When it comes to handling exceptions, unit tests can help ensure that the code responds appropriately to various error conditions. As a developer, you need to test that your code can handle exceptions gracefully. You can simulate these error conditions in a controlled environment so that you have more confidence in your code’s ability to handle exceptions that may occur.

For instance, in the case of a Flask application with an attendees endpoint, you may want to test how the application handles...
