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. Then you’ll build on your knowledge by exploring how to style React components and optimize them to make applications faster and more responsive. Once you’ve mastered the rest, you’ll learn how to write tests effectively and how to contribute to React and its ecosystem. By the end of this book, you'll be able to avoid the process of trial and error and developmental headaches. Instead, you’ll be able to use your new skills to efficiently build and deploy real-world React web applications you can be proud of.

Understanding universal applications

A universal application is an application that can run both on the server side and client side with the same code. In this section, we will look at the reasons why we should consider making our applications universal, and we will learn how React components can be easily rendered on the server side.

When we talk about JavaScript web applications, we usually think of client-side code that lives in the browser. The way they usually work is that the server returns an empty HTML page with a script tag to load the application. When the application is ready, it manipulates the DOM inside the browser to show the UI and to interact with users. This has been the case for the last few years, and it is still the way to go for a huge number of applications.

In this book, we have seen how easy it is to create applications using React components and how they work within the browser. What we have not seen yet is how React can render the same components on the server...
