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.

Summary

In this chapter, we learned how to compose our reusable components and make them communicate effectively. Props are a way to decouple components from each other and create a clean and well-defined interface.

Then, we went through some of the most interesting composition patterns in React. The first one was the so-called container and presentational pattern, which helps us separate the logic from the presentation and create more specialized components with a single responsibility.

We saw how React tried to solve the problem of sharing functionalities between components with mixins. Unfortunately, mixins solve those problems by adding several other ones, and they affect the maintainability of our applications. One way to achieve the same goal without adding complexity is by using HoCs, which are functions that take a component and return an enhanced one.
