React Design Patterns and Best Practices. - Second Edition

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.

Mixins

Components are great to achieve reusability, but what if different components in different domains share the same behavior?

We do not want duplicated code in our applications and React give us a tool that we can use when we want to share functionalities across various components—mixins.

Using mixins is deprecated, but it is worth understanding the problems they try to solve and see what the possible alternative solutions are. Also, it could happen that you might have to work on a legacy project that uses an older version of React, and it makes sense to know what mixins are and how to deal with them.

First of all, mixins work only with the createClass factory, so if you are using classes, you cannot use mixins, and that is one of the reasons why their use is discouraged.

Suppose you are using createClass in your application and you find yourself needing to write...
