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.

Data fetching

In the preceding section, we saw the different patterns we can put in place to share data between components in the tree.

It is now time to view how to fetch data in React and where the data fetching logic should be located.

The examples in this section use the fetch function to make web requests, which is a modern replacement for XMLHttpRequest.

At the time of writing, it is natively implemented in Chrome and FireFox and if you need to support different browsers, you must use the fetch polyfill by GitHub:

We are also going to use the public GitHub APIs to load some data and the endpoint we will use is the one that returns a list of gists, given a username:

Gists are snippets of code that can be easily shared between developers.

The first component that we will build is a simple list of the gists created by the user, called gaearon (Dan Abramov).

Let's delve into some code and create a class.

We use a class...
