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.

Running on physical devices

Up to this point, we've been running our application strictly on simulated hardware. It is important that we take it one step further and run on actual mobile devices to be sure the application performs in the way that we expect. In this section, we'll discuss running React Native applications on both iOS and Android devices.

Debugging on an iOS device

Before submitting your app to the App Store, it's highly recommended that you first test your app on physical hardware. In fact, the more devices you can test on, the better. Simulators are great for rapid development testing, but they don't give you an honest sense of how the app feels in your hands. Are the touch targets large enough? Are the animations smooth on lower end hardware? Does the app feel responsive? These are all questions that are best answered with actual device testing.

Not long ago, Apple required that developers pay $99/year to join the Apple Developer Program in order test...
