Designing React Hooks the Right Way

By: Fang Jin

Overview of this book

React hook creates a unique solution for using states in function components to orchestrate UI communication. They provide you with an easy interface to write custom data management solutions with low development and maintenance costs. Understanding how Hooks are designed enables you to use them more effectively, and this book helps you to do just that. This book starts with a custom-crafted solution to reveal why Hooks are needed in the first place. You will learn about the React engine and discover how each built-in Hook can manage a persistent value by hooking into it. You will walk through the design and implementation of each hook with code so that you gain a solid understanding. Finally, you'll get to grips with each Hook's pitfalls and find out how to effectively overcome them. By the end of this React book, you'll have gained the confidence to build and write Hooks for developing functional and efficient web applications at scale.

Example of a function component

A site is made up of pages, where each page contains a sidebar, a header, a content area, and a footer. All of them can be modeled with components. The layout component can sit at the top of the tree. When you zoom in, you find its children inside with a sub-structure. Just like a spider's web (see Figure 1.3) the tree structure cascades down from the outer level into the inner level.

Figure 1.3 – Web application layout

As UI engineers, we focus on the design of each component. Moreover, we pay close attention to the relationship between components. We want to know whether Title is built inside the main content or the sidebar. We want to know whether a header needs to be shared by multiple pages. You'll start to develop the skill to navigate between components among a tree.

Say we want to display a list of navigation links at the top of the page. Each link can be disabled if required. For enabled ones, we...
