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.

Chapter 9.  Improve the Performance of Your Applications

The effective performance of a web application is critical to providing a good user experience and improving conversions. The React library implements different techniques to render our components fast and to touch the DOM as little as possible. Applying changes to the DOM is usually expensive and so minimizing the number of operations is crucial.

However, there are some particular scenarios where React cannot optimize the process and it's up to the developer implementing specific solutions to make the application run smoothly.

In this chapter, we will go through the basic concepts of performance of React and we will learn how to use some APIs to help the library find the optimal path to update the DOM without degrading the user experience. We will also see some common mistakes that can harm our applications and make them slower.

Through the simple examples in this chapter, you will learn about the tools that we can import into our...
