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.

Using Redux with Hooks

After turning our todo application into a Redux-based application, we are now using higher-order components, instead of Hooks, in order to get access to the Redux state and action creators. This is the traditional way to develop a Redux application. However, in the latest versions of Redux, it is possible to use Hooks instead of higher-order components! We are now going to replace the existing connectors with Hooks.

Even with Hooks, the Provider component is still required in order to provide the Redux store to other components. The definition of the store and the provider can stay the same when refactoring from connect() to Hooks.

The latest version of React Redux offers various Hooks as an alternative to the connect() higher-order component. With these Hooks, you can subscribe to the Redux store, and dispatch actions without having to wrap your components...
