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.

Summary

Our journey through performance is finished and we can now optimize our applications to give users a better UX.

In this chapter, we learned how the reconciliation algorithm works and how React always tries to take the shortest path to apply changes to the DOM. We can also help the library to optimize its job by using the keys.

Always remember to use the production version of React when benchmarking with the Perf add-on to find the parts of your application that need optimization.

Once you've found your bottlenecks, you can apply one the techniques we have seen in this chapter to fix the issue. One of the first tools you can use is to extend the PureComponent and use immutable data to make your component re-render only when strictly needed.

Don't forget to avoid the common mistakes that make the PureComponent less effective, such as generating new functions inside the render method, or using constant as props.

We have learned how refactoring and designing your components structure...
