Overview of this book

React Native has completely revolutionized mobile development by empowering JavaScript developers to build world-class mobile apps that run natively on mobile platforms. This book will show you how to apply JavaScript and other front-end skills to build cross-platform React Native applications for iOS and Android using a single codebase. This book will provide you with all the React Native building blocks necessary to become an expert. We’ll give you a brief explanation of the numerous native components and APIs that come bundled with React Native including Images, Views, ListViews, WebViews, and much more. You will learn to utilize form inputs in React Native. You’ll get an overview of Facebook’s Flux data architecture and then apply Redux to manage data with a remote API. You will also learn to animate different parts of your application, as well as routing using React Native’s navigation APIs. By the end of the book, you will be able to build cutting-edge applications using the React Native framework.

Native APIs

Some native functionality does not fit nicely into a component. For these things, React Native also exposes several Native APIs that can be used in an application. Some of these we've talked about already in previous chapters. For instance, in Chapter 3, Styling and Layout in React Native, we introduced the StyleSheet API, which allows us to create stylesheets for our components. Others we'll cover in depth in future chapters on animation, fetching data, and performance optimization. Aside from these, there are a few that are of interest to us and our application right now.

ActionSheetIOS

In iOS applications, we often show context menus in the form of action sheets. These provide the user with nested options for a particular item on screen. In our application, we will use the ActionSheetIOS API to show the user a context menu that allows them to bookmark a NewsItem when they long press on the NewsItem itself, as shown in the following screenshot:
