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.

Appendix A – How many component types does React support?

In the published React documentation, it supports two component types. One is a function component, and another one is a class component. React supported the class component from the beginning:

class ClassComponent extends React.Component {
  render() {
    const { name } = this.props;
    return <h1>Hello, { name }</h1>;

Although the render function of a class component looks quite similar to what a function component returns and, most of the time, we can convert them in between, the class and function components are treated differently inside the React update process. Therefore, this book intentionally avoids mentioning the class component so as not to confuse any newcomer to React.

In general, a function component can be written shorter and simpler, and it's also easier in terms of development and testing because it has plain...
