Hands-On Design Patterns with React Native

By: Mateusz Grzesiukiewicz

Overview of this book

React Native helps developers reuse code across different mobile platforms like iOS and Android. This book will show you effective design patterns in the React Native world and will make you ready for professional development in big teams. The book will focus only on the patterns that are relevant to JavaScript, ECMAScript, React and React Native. However, you can successfully transfer a lot of the skills and techniques to other languages. I call them “Idea patterns”. This book will start with the most standard development patterns in React like component building patterns, styling patterns in React Native and then extend these patterns to your mobile application using real world practical examples. Each chapter comes with full, separate source code of applications that you can build and run on your phone. The book is also diving into architectural patterns. Especially how to adapt MVC to React environment. You will learn Flux architecture and how Redux is implementing it. Each approach will be presented with its pros and cons. You will learn how to work with external data sources using libraries like Redux thunk and Redux Saga. The end goal is the ability to recognize the best solution for a given problem for your next mobile application.

Detailed Flux diagram

Let's look at the Flux architecture in a more formalized way. Here is a little diagram that shows how the simplified architecture looks:

Flux diagram from official documentation: https://github.com/facebook/flux

Each of the pieces in the preceding diagram has its own purpose in the circular chain:

  • Dispatcher: The manager of what's happening in the application. This manages actions and provides them to registered callbacks. All actions need to pass through the Dispatcher. The Dispatcher must expose the register and unregister methods to register/unregister callbacks, and must expose the dispatch method, which dispatches actions.
  • Stores: The application consists of multiple stores that register callback(s) in the Dispatcher. Each store needs to expose a public constructor method that accepts the Dispatcher argument. The constructor is responsible...
