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.

In this chapter, we first learned what MobX is, which elements it consists of, and how they work together. Then, we learned how to use MobX for state management in practice. We also learned how to connect a MobX store to React components, by using the inject and observer higher-order components. Next, we replaced the higher-order components with Hooks, which made our code much more clean and concise. We also learned how to use a Local Store Hook to deal with complex local state in MobX. Finally, we learned how to migrate an existing MobX application to Hooks, and we recapped what the trade-offs of using MobX are.

This chapter marks the end of this book. In this book, we started out with a motivation to use Hooks. We learned that there are common problems in React apps that cannot be easily solved without Hooks. Then, we created our first component using Hooks and compared...
