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.

As soon as we become familiar with HoCs, we realize how powerful they are and how we can get the most out of them.

There is a popular library called recompose which provides many useful HoCs and also a way to compose them nicely.

The HoCs that the library offers are small utilities that we can use to wrap our components, moving away some logic from them and making them more dumb and reusable.

Consider that your component is receiving a user object from an API, and this user object has many attributes.

Letting components receive arbitrary objects is not a good practice because it relies on the fact that the component knows the shape of the object and, most importantly, if the object changes, the component breaks.

A better way for a component to receive props from the parent is to define each single property using primitives.

So, we have a Profile component to display username and age; it looks like this:

const Profile = ({ user }) => (
