Learn React Hooks

By: Daniel Bugl

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.

Redux and Hooks

In the previous chapter we learned about React class components, and how to migrate from an existing class component-based project to a Hook-based one. Then, we learned about the trade-offs between the two solutions, and we discussed when and how existing projects should be migrated.

In this chapter, we are going to turn the ToDo application that we created in the previous chapter into a Redux application. First, we are going to learn what Redux is, including the three principles of Redux. We are also going to learn when it makes sense to use Redux in an app, and that it is not appropriate for every app. Furthermore, we are going to learn how to handle state with Redux. Afterward, we are going to learn how to use Redux with Hooks, and how to migrate an existing Redux application to Hooks. Finally, we are going to learn the trade-offs of Redux, in order to be able...
