React Design Patterns and Best Practices - Second Edition

By: Carlos Santana Roldán

Overview of this book

React is an adaptable JavaScript library for building complex UIs from small, detached bits called components. This book is designed to take you through the most valuable design patterns in React, helping you learn how to apply design patterns and best practices in real-life situations. You’ll get started by understanding the internals of React, in addition to covering Babel 7 and Create React App 2.0, which will help you write clean and maintainable code. To build on your skills, you will focus on concepts such as class components, stateless components, and pure components. You'll learn about new React features, such as the context API and React Hooks that will enable you to build components, which will be reusable across your applications. The book will then provide insights into the techniques of styling React components and optimizing them to make applications faster and more responsive. In the concluding chapters, you’ll discover ways to write tests more effectively and learn how to contribute to React and its ecosystem. By the end of this book, you will be equipped with the skills you need to tackle any developmental setbacks when working with React. You’ll be able to make your applications more flexible, efficient, and easy to maintain, thereby giving your workflow a boost when it comes to speed, without reducing quality.

About Testing and Debugging

React, thanks to its components, makes it easy to test our applications. There are many different tools that we can use to create tests with React, and here we'll cover the most popular ones to understand the benefits they provide.

Jest is an all-in-one testing framework solution, maintained by Christopher Pojer from Facebook and contributors within the community, and aims to give you the best developer experience. We will look at both ways of building the best test environment.

By the end of the chapter, you'll be able to create a test environment from scratch and write tests for your application's components.

In this chapter, we will look at the following topics:

  • Why it is important to test our applications, and how this helps developers move faster
  • How to set up a Jest environment to test components using Enzyme
  • What Enzyme is and...
