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 3: Hooking into React

In the previous chapter, we learned to perform actions inside a function component with our crafted states. In this chapter, we will go through the challenges we face in creating a good state solution, and then see how React builds the solution with the underlying Hook. We will then introduce what a hook is and get to know it, as well as its calling order, and learn how to avoid running into conditional hook issues in real applications. The chapter also includes two bonus topics in the Appendix section, React Fiber and Current and WorkInProgress Scenes.

We will cover the following topics in this chapter:

  • Creating good state solution
  • Introducing a React Hook
  • What is a hook?
  • Questions and answers
  • Appendix
