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.

Handling state with Redux

State management with Redux is actually really similar to using a Reducer Hook. We first define the state object, then actions, and finally, our reducers. An additional pattern in Redux is to create functions that return action objects, so-called action creators. Furthermore, we need to wrap our whole app with a Provider component, and connect components to the Redux store in order to be able to use Redux state and action creators.

Installing Redux

First of all, we have to install Redux, React Redux, and Redux Thunk. Let us look at what each one does individually:

  • Redux itself just deals with JavaScript objects, so it provides the store, deals with actions and action creators, and handles reducers...
