Designing React Hooks the Right Way

By: Fang Jin

Overview of this book

React hook creates a unique solution for using states in function components to orchestrate UI communication. They provide you with an easy interface to write custom data management solutions with low development and maintenance costs. Understanding how Hooks are designed enables you to use them more effectively, and this book helps you to do just that. This book starts with a custom-crafted solution to reveal why Hooks are needed in the first place. You will learn about the React engine and discover how each built-in Hook can manage a persistent value by hooking into it. You will walk through the design and implementation of each hook with code so that you gain a solid understanding. Finally, you'll get to grips with each Hook's pitfalls and find out how to effectively overcome them. By the end of this React book, you'll have gained the confidence to build and write Hooks for developing functional and efficient web applications at scale.

Chapter 9: Use Custom Hooks to Reuse Logic

In the previous chapter, we learned how the useRef hook is designed and how to use a ref for a state without updating the screen. In this chapter, we will gather all the hooks we have learned about so far and see how to create a custom hook for our own needs. We will introduce what a custom hook is and then write some custom hooks step by step, including useToggle, useWindow, useAsync, useDebounced, useClickOutside, useCurrent, and useProxy.

We will cover the following topics in this chapter:

  • Reviewing React hooks
  • useToggle
  • useWindow
  • useAsync
  • useDebounced
  • useClickOutside
  • useCurrent
  • useProxy
  • Questions and answers
