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.

Chapter 1: Introducing React and React Hooks

  1. What are React's three fundamental principles?
    • Declarative: Instead of telling React how to do things, we tell it what we want. As a result, we can easily design our applications and React will efficiently update and render just the right components when data changes.
    • Component-based: React encapsulates components that manage their own state and views, then allows us to compose them to create complex user interfaces.
    • Learn once, write anywhere: React does not make assumptions about your technology stack...
