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.

Installation and configuration

After you create a new React application using create-react-app, the first thing you need to do is to install React Router v4.x, using this command:

  npm install react-router-dom

You probably are confused about why we are installing react-router-dom instead of react-router. React Router contains all the common components of react-router-dom and react-router-native. That means that if you are using React for the web, you should use react-router-dom, and if you are using React Native, you need to use react-router-native. The react-router-dom package was created originally to contain version 4, and react-router was using version 3. The react-router-dom has some improvements over react-router. They are listed here:

  • The improved <Link> component (which renders <a>).
  • Includes <BrowserRouter>, which interacts with the browser window...
