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.

Summary

Knowing all the best practices is always a good thing, but sometimes, being aware of anti-patterns helps us avoid taking the wrong path. Most importantly, learning the reasons why some techniques are considered bad practice helps us understand how React works, and how we can use it effectively.

In this chapter, we covered four different ways of using components that can harm the performance and behavior of our web applications.

For each one of those, we used an example to reproduce the problem and supplied the changes to apply in order to fix the issue.

We learned why using properties to initialize the state can result in inconsistencies between the state and the properties. We also saw how using the wrong key attribute can produce bad effects on the reconciliation algorithm. Finally, we learned why spreading non-standard properties to DOM elements is considered an anti-pattern.

In the next chapter, we will look into the new React Hooks.
