Overview of this book

Over the years, React and React Native has proven itself among JavaScript developers as a popular choice for a complete and practical guide to the React ecosystem. This fourth edition comes with the latest features, enhancements, and fixes to align with React 18, while also being compatible with React Native. It includes new chapters covering critical features and concepts in modern cross-platform app development with React. From the basics of React to popular components such as Hooks, GraphQL, and NativeBase, this definitive guide will help you become a professional React developer in a step-by-step manner. You'll begin by learning about the essential building blocks of React components. As you advance through the chapters, you'll work with higher-level functionalities in application development and then put your knowledge to work by developing user interface components for the web and native platforms. In the concluding chapters, you'll learn how to bring your application together with robust data architecture. By the end of this book, you'll be able to build React applications for the web and React Native applications for multiple mobile platforms.

Scaling the architecture

By now, you probably have a pretty good grip of using Context, combining it with reducer functions, and using it to implement sound information architecture for React applications. The question then becomes, how sustainable is this approach, and can it handle arbitrarily large and complex applications?

Context is a good way to handle the state for your application if this state isn't continuously updated. By dividing your Context into different smaller Context instances, it becomes more scalable. You can predict what's going to happen as the result of any given action because everything is explicit. It's declarative, it's unidirectional, and without side effects. But, it isn't without challenges.

The limiting factor with Context is also its bread and butter; because everything is explicit, applications that need to scale up in terms of feature count and complexity ultimately end up with more moving parts. There's nothing...
