Overview of this book

Filled with useful React patterns that you can use in your projects straight away, this book will help you save time and build better web applications with ease. React 17 Design Patterns and Best Practices is a hands-on guide for those who want to take their coding skills to a new level. You’ll spend most of your time working your way through the principles of writing maintainable and clean code, but you’ll also gain a deeper insight into the inner workings of React. As you progress through the chapters, you’ll learn how to build components that are reusable across the application, how to structure applications, and create forms that actually work. Then you’ll build on your knowledge by exploring how to style React components and optimize them to make applications faster and more responsive. Once you’ve mastered the rest, you’ll learn how to write tests effectively and how to contribute to React and its ecosystem. By the end of this book, you'll be able to avoid the process of trial and error and developmental headaches. Instead, you’ll be able to use your new skills to efficiently build and deploy real-world React web applications you can be proud of.

Introducing React Suspense with SWR

React Suspense was introduced in React 16.6. Right now (April 2021) this feature is still experimental and you should not use it in your production applications. 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.

WARNING: The new React Suspense feature is still experimental so I recommend you do not use it on production because it is not yet available in a stable release.
