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.

Anti-Patterns to be Avoided

In this book, you've learned how to apply best practices when writing a React application. In the first few chapters, we revisited the basic concepts to build a solid understanding, and then we took a leap into more advanced techniques in the following chapters.

You should now be able to build reusable components, make components communicate with each other, and optimize an application tree to get the best performance. However, developers make mistakes, and this chapter is all about the common anti-patterns we should avoid when using React.

Looking at common errors will help you to avoid them and will aid your understanding of how React works and how to build applications in the React way. For each problem, we will see an example that shows how to reproduce and solve it.

In this chapter, we will cover the following topics:

  • Initializing the state...
