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.

When testing in the console is not enough, and we want to inspect our application while it is running inside the browser, we can use the React Developer Tools.

You can install them as a Chrome extension from the following URL:

The installation adds a tab to the Chrome Dev Tools called React where you can inspect the rendered tree of components and check which properties they have received and what their state is at a particular point in time.

Props and state can be read, and they can be changed in real time to trigger updates in the UI and see the results straightaway.

This is a must-have tool and in the most recent versions it has a new feature that can be enabled by ticking the Trace React Updates checkbox.

When this functionality is enabled we can use our application and visually see which components get updated when we perform a particular action. The updated components...
