Learn React Hooks

Overview of this book

React Hooks revolutionize how you manage state and effects in your web applications. They enable you to build simple and concise React.js applications, along with helping you avoid using wrapper components in your applications, making it easy to refactor code. This React book starts by introducing you to React Hooks. You will then get to grips with building a complex UI in React while keeping the code simple and extensible. Next, you will quickly move on to building your first applications with React Hooks. In the next few chapters, the book delves into various Hooks, including the State and Effect Hooks. After covering State Hooks and understanding how to use them, you will focus on the capabilities of Effect Hooks for adding advanced functionality to React apps. You will later explore the Suspense and Context APIs and how they can be used with Hooks. Toward the concluding chapters, you will learn how to integrate Redux and MobX with React Hooks. Finally, the book will help you develop the skill of migrating your existing React class components, and Redux and MobX web applications to Hooks. By the end of this book, you will be well-versed in building your own custom Hooks and effectively refactoring your React applications.

Building Your Own Hooks

In the previous chapter, we learned about the limitations and rules of Hooks. We learned where to call Hooks, why the order of Hooks matters, and the naming conventions for Hooks. Finally, we learned about enforcing the rules of Hooks and dealing with useEffect dependencies.

In this chapter, we are going to learn how to create custom Hooks by extracting existing code from our components. We are also going to learn how to use custom Hooks and how Hooks can interact with each other. Then, we are going to learn how to write tests for our custom Hooks. Finally, we are going to learn about the full React Hooks API.

The following topics will be covered in this chapter:

  • Extracting custom Hooks
  • Using custom Hooks
  • Interactions between Hooks
  • Testing Hooks
  • Exploring the React Hooks API
