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.

Test-driven development with Flask

TDD is a software development approach where you write automated tests before writing the actual code. The process involves writing a test case for a specific feature or functionality and then writing the minimum amount of code necessary to make the test pass. Once the test passes, you write additional tests to cover different edge cases and functionality until you have fully implemented the desired feature.

Using Flask with an attendee endpoint as a case study, the TDD process might look like this:

  1. Define the feature: The first step is to define the feature you want to implement. In this case, the feature is an endpoint that allows users to view a list of attendees for an event.
  2. Write a test case: Next, you must write a test case that defines the expected behavior of the endpoint. For example, you might write a test that checks that the endpoint returns a JSON response with a list of attendees.
  3. Run the test: You then run the test...
