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 first defined two pages for our blog: the home page and a page for single posts. We also created a component for the HeaderBar. Afterward, we implemented routing by defining routes, links to the single posts, and links back to the main page. Finally, we used routing Hooks to implement dynamic navigation when creating a new post, and implemented a footer that shows the current URL.

Routing is very important, and is used in almost every application. We now know how to define separate pages and how to link between them. Furthermore, we learned how to dynamically navigate between pages using Hooks. We also learned how to access routing information with Hooks for more advanced use cases.

There are many more things that the Navi library can do. However, this book focuses on Hooks, so most features of Navi are out of scope. For example, we can fetch data using...
