Overview of this book

Filled with useful React patterns that you can use in your projects straight away, this book will help you save time and build better web applications with ease. React 17 Design Patterns and Best Practices is a hands-on guide for those who want to take their coding skills to a new level. You’ll spend most of your time working your way through the principles of writing maintainable and clean code, but you’ll also gain a deeper insight into the inner workings of React. As you progress through the chapters, you’ll learn how to build components that are reusable across the application, how to structure applications, and create forms that actually work.

The CSS modules are CSS files in which all class names and animation names are scoped locally by default. Let's see how we can use them in our projects; but first, we need to configure Webpack.

Webpack 5

Before diving into CSS modules and learning how they work, it is important to understand how they were created and the tools that support it.

In Chapter 2, Cleaning Up Your Code, we looked at how we can write ES6 code and transpile it using Babel and its presets. As soon as the application grows, you may want to split your code base into modules as well.

You can use Webpack or Browserify to divide the application into small modules that you can import whenever you need them, while still creating a big bundle for the browser. These tools are called...
