React Design Patterns and Best Practices

By: Michele Bertoli

Overview of this book

Taking a complete journey through the most valuable design patterns in React, this book demonstrates how to apply design patterns and best practices in real-life situations, whether that’s for new or already existing projects. It will help you to make your applications more flexible, perform better, and easier to maintain – giving your workflow a huge boost when it comes to speed without reducing quality. We’ll begin by understanding the internals of React before gradually moving on to writing clean and maintainable code. We’ll build components that are reusable across the application, structure applications, and create forms that actually work. Then we’ll style React components and optimize them to make applications faster and more responsive. Finally, we’ll write tests effectively and you’ll learn how to contribute to React and its ecosystem. By the end of the book, you’ll be saved from a lot of trial and error and developmental headaches, and you will be on the road to becoming a React expert.

Chapter 2. 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 important 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 in order to apply the best practices.

In this chapter, we will cover the following topics:

  • What JSX is and why we should use it

  • What Babel is and how we can use it to write modern JavaScript code

  • The main features of JSX and the differences between HTML and JSX

  • Best practices to write JSX in an elegant and maintainable way

  • How linting, and ESLint in particular, can make our JavaScript...
