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.

The example in the previous section should clearly explain how to set up a universal application in React. It is pretty straightforward, and the main focus is on getting things done. However, in a real-world application, we will likely want to load some data instead of a static React component, such as App in the example.

Let’s assume, for example, we want to load Dan Abramov’s gists on the server and return the list of items from the Express app we just created.

In the data fetching examples in Chapter 12, Managing Data, we looked at how we can use useEffect to fire the data loading. That wouldn’t work on the server because components do not get mounted on the DOM and the life cycle Hook never gets fired.

Using Hooks that were executed earlier will not work either because the data fetching operation is async, while renderToString is not. For that reason, we have to find a way to load the data beforehand and pass it to the...
