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.

Built-in components you need to know about

React Native is growing fast and changing often. I have selected a curated list of components that are likely to stay within the API for a long time. We will spend some time learning them so that we will be able to proceed faster later on in this book. Any further examples will rely on these components and will assume that you know what these components are for.

The ScrollView component

So far, we know about three components: View , Text, and StyleSheet. Now, imagine a case where we have a lot of rows to show in the application—something such as table of information pops into my mind. Obviously, it will be a long table, but the screen is small, so we will make it scrollable...
