React Design Patterns and Best Practices - Second Edition

By: Carlos Santana Roldán

Overview of this book

React is an adaptable JavaScript library for building complex UIs from small, detached bits called components. This book is designed to take you through the most valuable design patterns in React, helping you learn how to apply design patterns and best practices in real-life situations. You’ll get started by understanding the internals of React, in addition to covering Babel 7 and Create React App 2.0, which will help you write clean and maintainable code. To build on your skills, you will focus on concepts such as class components, stateless components, and pure components. You'll learn about new React features, such as the context API and React Hooks that will enable you to build components, which will be reusable across your applications. The book will then provide insights into the techniques of styling React components and optimizing them to make applications faster and more responsive. In the concluding chapters, you’ll discover ways to write tests more effectively and learn how to contribute to React and its ecosystem. By the end of this book, you will be equipped with the skills you need to tackle any developmental setbacks when working with React. You’ll be able to make your applications more flexible, efficient, and easy to maintain, thereby giving your workflow a boost when it comes to speed, without reducing quality.

React-refetch

Now, our HoC works as expected and we can reuse it across the codebase without any problems. The question is, what should we do if we need more features?

For example, we may want to post some data to the server or fetch the data again when the props change. Also, we may not want to load the data on componentDidMount but apply some lazy loading patterns instead.

We could write all the features we need, but there is an existing library that has a lot of useful functionalities, and it is ready to be used.

The library is called react-refetch, and it is maintained by developers from Heroku. Let's see how we can use it effectively to replace our HoC.

From the previous section, we have a List component, which is a stateless functional component that can receive a collection of gists; it displays the description for each one of them:
