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 6. Write Code for the Browser

There are some specific operations we can do when we work with React and the browser. For example, we can ask our users to enter some information using forms, and we will look at how, in React, we can apply different techniques to deal with them.

We can implement Uncontrolled Components and let the fields keep their internal states, or we can use Controlled ones, where we have full control over the state of the fields.

In this chapter, we will also look at how events in React work and how the library implements some advanced techniques to give us a consistent interface across different browsers. We will also look at some interesting solutions that the React team has implemented to make the event system very performant.

After the events, we will jump into refs to look at how we can access the underlying DOM nodes in our React components. This represents a powerful feature, but it should be used carefully because it breaks some of the conventions that make...
