Overview of this book

React helps you work smarter, not harder — but to reap the benefits of this popular JavaScript library and its components, you need a straightforward guide that will teach you how to make the most of it. React 18 Design Patterns and Best Practices will help you use React effectively to make your applications more flexible, easier to maintain, and improve their performance, while giving your workflow a huge boost. With a better organization of topics and knowledge about best practices added to your developer toolbox, the updated fourth edition ensures an enhanced learning experience. The book is split into three parts; the first will teach you the fundamentals of React patterns, the second will dive into how React works, and the third will focus on real-world applications. All the code samples are updated to the latest version of React and you’ll also find plenty of new additions that explore React 18 and Node 19’s newest features, alongside MonoRepo Architecture and a dedicated chapter on TypeScript. By the end of this book, you'll be able to efficiently build and deploy real-world React web applications.

Template literals

In TypeScript, template literals are based on string literal types and can be expanded into multiple strings using unions. These types are useful for defining a theme name, for instance:

type Theme = 'light' | 'dark' 

Theme is a union type that can only be assigned one of the two string literal types: 'light' or 'dark'. This provides type safety and prevents runtime errors caused by passing an invalid value as the theme name.

Using this approach, you can define a set of possible values for a variable, argument, or parameter and ensure that only valid values are used at compile time. This makes your code more reliable and easier to maintain.
