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.

Clean Up Your Code

This chapter assumes that you already have experience with JSX and you want to improve your skills to use it effectively. To use JSX without any problems or unexpected behaviors, it is essential to understand how it works under the hood, and the reasons why it is a useful tool for building UIs.

Our goal is to write clean and maintainable JSX code, and to achieve that we have to know where it comes from, how it gets translated to JavaScript, and which features it provides.

In the first section, we will do a little step back, but please bear with me because it is crucial to master the basics to apply the best practices.

In this chapter, we will cover the following topics:

  • What is JSX, and why should we use it?
  • What is Babel and how can we use it to write modern JavaScript code?
  • The main features of JSX and the differences between HTML and JSX
  • Best practices to...
