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.

Also known as Vjeux on the Internet, Christopher works at Facebook and contributes to React. In his talk, he went through all the problems related to CSS at scale that they were facing at Facebook.

It is worth understanding all of them, because some are pretty common and they will help us introduce concepts such as inline styles and locally scoped class names.

The following slide, taken from the presentation, lists the main issues with CSS:

The first well-known problem of CSS is that all the selectors are global. No matter how we organize our styles, using namespaces or a BEM-like methodology, in the end, we are always polluting the global namespace, which we all know is wrong. It is not only wrong on principle, but it also leads to many errors in big codebases, and it makes maintainability very hard in...
