React Design Patterns and Best Practices

By: Michele Bertoli

Overview of this book

Taking a complete journey through the most valuable design patterns in React, this book demonstrates how to apply design patterns and best practices in real-life situations, whether that’s for new or already existing projects. It will help you to make your applications more flexible, perform better, and easier to maintain – giving your workflow a huge boost when it comes to speed without reducing quality. We’ll begin by understanding the internals of React before gradually moving on to writing clean and maintainable code. We’ll build components that are reusable across the application, structure applications, and create forms that actually work. Then we’ll style React components and optimize them to make applications faster and more responsive. Finally, we’ll write tests effectively and you’ll learn how to contribute to React and its ecosystem. By the end of the book, you’ll be saved from a lot of trial and error and developmental headaches, and you will be on the road to becoming a React expert.

A real-world testing example

We have a working test set up and a clear understanding of what the different tools and libraries can do for us. The next thing to do is to test a real-world component.

The Button we used in the previous example was great and we should always try to make our components as simple as possible; but sometimes we need to implement different kinds of logic and state, which makes the tests more challenging.

The component we are going to test is TodoTextInput from the Redux TodoMVC example:

You can easily copy it into your Jest project folder.

It represents a nice example because it has various props, its class names change according to the props it receives, and it has three event handlers that implement a bit of logic that we can test.

The TodoMVC example is a standard way of creating a real-world application with the different frameworks in order to compare their features and...
