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.

Common solutions

We have seen how using the PureComponent can help us to tell React when a subtree has to be rendered or not. If utilized in the right way, it could improve the performance of our applications a lot. It is also important to stress that is should be used only after the application has been monitored and the bottleneck has been found.

There are some tricky situations where extending the PureComponent does not give the expected results; usually, the cause is that our props or state attributes are changing even if we think they are not. Sometimes it is not easy to figure out which props are causing the component to re-render or we do not know which components can be optimized with the PureComponent.

Most of the time, refactoring the components and putting the state in the right place can greatly assist the optimization of the application.

In this section, we will look at some common tools and solutions to solve re-rendering issues, figuring out which components can be optimized...
