Overview of this book

Filled with useful React patterns that you can use in your projects straight away, this book will help you save time and build better web applications with ease. React 17 Design Patterns and Best Practices is a hands-on guide for those who want to take their coding skills to a new level. You’ll spend most of your time working your way through the principles of writing maintainable and clean code, but you’ll also gain a deeper insight into the inner workings of React. As you progress through the chapters, you’ll learn how to build components that are reusable across the application, how to structure applications, and create forms that actually work. Then you’ll build on your knowledge by exploring how to style React components and optimize them to make applications faster and more responsive. Once you’ve mastered the rest, you’ll learn how to write tests effectively and how to contribute to React and its ecosystem. By the end of this book, you'll be able to avoid the process of trial and error and developmental headaches. Instead, you’ll be able to use your new skills to efficiently build and deploy real-world React web applications you can be proud of.

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.

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 they help developers move faster
  • How to set up a Jest environment to test components using Enzyme
  • What React Testing Library is and why it is a must-have for testing React applications
  • How...
