React Design Patterns and Best Practices

By: Michele Bertoli

Overview of this book

Taking a complete journey through the most valuable design patterns in React, this book demonstrates how to apply design patterns and best practices in real-life situations, whether that’s for new or already existing projects. It will help you to make your applications more flexible, perform better, and easier to maintain – giving your workflow a huge boost when it comes to speed without reducing quality. We’ll begin by understanding the internals of React before gradually moving on to writing clean and maintainable code. We’ll build components that are reusable across the application, structure applications, and create forms that actually work. Then we’ll style React components and optimize them to make applications faster and more responsive. Finally, we’ll write tests effectively and you’ll learn how to contribute to React and its ecosystem. By the end of the book, you’ll be saved from a lot of trial and error and developmental headaches, and you will be on the road to becoming a React expert.

Knowing all the best practices is always a good thing, but sometimes being aware of anti-patterns help 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 props, and we discovered why mutating the state is bad for performance. We also saw how using the wrong key attribute can produce bad effects on the reconciliation algorithm; and, finally, we learned why spreading non-standard props to DOM elements is considered an anti-pattern.
