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.

Names of Hooks

There is a convention that Hook functions should always be prefixed with use, followed by the Hook name starting with a capital letter; for example: useState, useEffect, and useResource. This is important, because otherwise we would not know which JavaScript functions are Hooks, and which are not. Especially when enforcing the rules of Hooks, we need to know which functions are Hooks so that we can make sure they are not being called conditionally or in loops.

As we can see, naming conventions are not technically required, but they make life a lot easier for developers. Knowing the difference between normal functions and Hooks makes it very easy to automatically enforce the rules of Hooks. In the next section, we are going to learn how to automatically enforce the rules using the eslint tool.
