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 built a ToDo app using React class components. We started by designing the app structure, then implemented static components, and finally, we made them dynamic. In the next section, we learned how to migrate an existing project using class components, to function components using Hooks. Finally, we learned about the trade-offs of class components, when class components or Hooks should be used, and how one should go about migrating an existing project to Hooks.

We have now seen in practice how React class components differ to function components with Hooks. Hooks make our code much more concise and easier to read and maintain. We have also learned that we should gradually migrate our components from class components to function components with Hooks—there is no need to immediately migrate the whole application.

In the next chapter, we are...
