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.

Improving the Performance of Your Applications

The effective performance of a web application is critical to providing a good user experience and improving conversions. The React library implements different techniques to render our components fast and to touch the Document Object Model (DOM) as little as possible. Applying changes to the DOM is usually expensive, and so minimizing the number of operations is crucial.

However, there are some particular scenarios where React cannot optimize the process, and it's up to the developer to implement specific solutions to make the application run smoothly.

In this chapter, we will go through the basic concepts of React and we will learn how to use some APIs to help the library find the optimal path to update the DOM without degrading the user experience. We will also see some common mistakes that can harm our applications and make...
