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.

Summary

In this chapter, we started out by reimplementing the useState function, by making use of global state and closures. We then learned that in order to implement multiple Hooks, we need to use a state array instead. By using a state array, however, we were forced to keep the order of Hooks consistent across function calls. This limitation made conditional Hooks and Hooks in loops impossible. We then learned about possible alternatives to the Hook API, their trade-offs, and why the final API was chosen. Finally, we learned how to solve the common problems that stem from the limitations of Hooks. We now have a solid understanding of the inner workings and limitations of Hooks. Furthermore, we learned about the State Hook in depth.

In the next chapter, we are going to create a blog application using the State Hook, and learn how to combine multiple Hooks.
