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.

Using the State Hook

Now that you've learned about the principles of React and had an introduction to Hooks, we are going to learn about the State Hook in depth. We will start by learning how the State Hook works internally by reimplementing it ourselves. Next, we learn about some of the limitations of Hooks, and why they exist. Then, we will learn about possible alternative Hook APIs and their associated problems. Finally, we learn how to solve the common problems that result from the limitations of Hooks. By the end of this chapter, we will know how to use the State Hook in order to implement stateful function components in React.

The following topics will be covered in this chapter:

  • Reimplementing the useState Hook as a simple function, which accesses the global state
  • Comparing our reimplementation to real React Hooks and learning about the differences
  • Learning about...
