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.

Mocha is a flexible testing framework

In this section, we will see how it's possible to achieve the same results with Mocha in order to make it clear that, with React, you can use any testing framework. Also, it is good to learn the main differences between Jest, which is an integrated test framework and tries to automate all operations to provide a smooth developer experience, and Mocha, which does not make any assumptions on the tools you need. With Mocha, it is up to you to install all the different packages you need to test React in the right way.

Let's create a new folder and initialize a new npm package with:

npm init

The first thing to install is the mocha package:

npm install --save-dev mocha

As with Jest, to be able to write ES2015 code and JSX we have to ask Babel for some help: To make it work with Mocha, we have to install the following packages:

npm install --save-dev babel-register babel-preset-es2015 babel-

Now that Mocha and Babel have been installed...
