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.

Prop types

Our goal is to write truly reusable components and to do that we have to define their interface in the clearest possible way.

If we want our components to be reused across the application, it is crucial to make sure that our components and their parameters are well-defined and straightforward to use.

With React, there is a powerful tool that lets us express, in a very simple way, the name of the props that a component expects to receive and some validation rules for each one of them.

The rules relate to the type of the property as well as to whether the property is optional or required. There is also the option to write custom validation functions.

Let's start with a very simple example:

const Button = ({ text }) => <button>{text}</button> 
Button.propTypes = { 
  text: React.PropTypes.string, 

In the snippet above, we created a stateless functional component that receives a text prop of type string.

Great, now every developer that comes...
