Overview of this book

React helps you work smarter, not harder — but to reap the benefits of this popular JavaScript library and its components, you need a straightforward guide that will teach you how to make the most of it. React 18 Design Patterns and Best Practices will help you use React effectively to make your applications more flexible, easier to maintain, and improve their performance, while giving your workflow a huge boost. With a better organization of topics and knowledge about best practices added to your developer toolbox, the updated fourth edition ensures an enhanced learning experience. The book is split into three parts; the first will teach you the fundamentals of React patterns, the second will dive into how React works, and the third will focus on real-world applications. All the code samples are updated to the latest version of React and you’ll also find plenty of new additions that explore React 18 and Node 19’s newest features, alongside MonoRepo Architecture and a dedicated chapter on TypeScript. By the end of this book, you'll be able to efficiently build and deploy real-world React web applications.

Introducing the React Context API

The React Context API has come a long way since it was first introduced as an experimental feature. Since version 16.3.0, it has been officially added to React and has become a game-changer for many developers. In fact, many are now using the new Context API instead of Redux. The Context API allows you to share data between components without having to pass a prop to every child component.

To illustrate how to use the new Context API, let’s revisit the example from Chapter 8, React Hooks, where we fetched GitHub issues using React Hooks, but this time by using the Context API instead.

Creating our first context

The first thing you need to do is to create the issue context. For this, you can create a folder called contexts inside your src folder, where you will add the Issue.tsx file.

Then, you need to import some functions from React and axios:

import { FC, createContext, useState, useEffect, ReactElement, useCallback }...
