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.

React is a JavaScript library for building efficient and extensible web applications. React is developed by Facebook and is used in many large-scale web applications, such as Facebook, Instagram, Netflix, and WhatsApp Web.

React Hooks were introduced in the React 16.8 release and solve many common problems with React projects. Hooks make components less complex, more concise, and easier to read and refactor. Furthermore, they make many React features much easier to use and understand, and we avoid having to use wrapper components.

This book is the definitive guide to learning React Hooks. You are going to learn all the facets of React Hooks for managing state and effects in React components, as well as using other React features, such as context, via Hooks. With practical examples, you are going to learn how to develop large-scale and efficient applications with code that is extensible and easy to understand.

The book also delves into advanced concepts, such as using Hooks in combination with libraries like Redux and MobX. Furthermore, you are going to learn when and how existing projects can be efficiently migrated to React Hooks.
