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 React Suspense with SWR

React Suspense was introduced in React 16.6. Suspense lets you suspend component rendering until a condition is met. You can render a loading component or anything you want as a fallback of Suspense.

Right now, there are only two use cases for this:

  • Code splitting: When you split your application and you’re waiting to download a chunk of your app when a user wants to access it.
  • Data fetching: When you’re fetching data.

In both scenarios, you can render a fallback, which can normally be a loading spinner, some loading text, or even better, a placeholder skeleton.

Introducing SWR

Stale-While-Revalidate (SWR) is a React Hook for data fetching; it is an HTTP cache invalidation strategy. SWR is a strategy to first return the data from cache (stale), then send the fetch request (revalidate), and finally, return with up-to-date data, and was developed by Vercel, the company that created Next.js.
