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 looked at a lot of interesting topics. We started by going through the problems of CSS at scale, specifically, the problems that they had at Facebook while dealing with CSS.

We learned how inline styles work in React and why it is good to colocate the styles within components. We also looked at the limitations of inline styles.

Then, we moved on to Radium, which solves the main problems of inline styles, giving us a clear interface to write our CSS in JavaScript. For those who think that inline styles are a bad solution, we moved into the world of CSS modules, setting up a simple project from scratch.

Importing the CSS files into our components makes the dependencies clear, and scoping the class names locally avoids clashes. We looked at how CSS module's composes is a great feature, and how we can use it in conjunction with Atomic CSS to create...
