Overview of this book

React Native's ability to build performant mobile applications with JavaScript has resulted in its popularity amongst developers. Developers now have the luxury to create incredible mobile experiences that look and feel native to their platforms with the comfort of a well-known language and the popular React.js library. This book will show you how to build your own native mobile applications for the iOS and Android platforms while leveraging the finesse and simplicity of JavaScript and React. Throughout the book you will build three projects, each of increasing complexity. You will also link up with the third-party Facebook SDK, convert an app to support the Redux architecture, and learn the process involved in making your apps available for sale on the iOS App Store and Google Play. At the end of this book, you will have learned and implemented a wide breadth of core APIs and components found in the React Native framework that are necessary in creating great mobile experiences.

Setting up a boilerplate project

Using the React Native command-line tools, I created a project titled AdditionalComponents. In it, the structure is a lot more simplified than our previous projects.

In each platform-specific index file at the root of the project, it imports an App component from our app folder and registers it to AppRegistry:

// AdditionalComponents/index.ios.js 

import App from './app'; 
import { AppRegistry } from 'react-native'; 
AppRegistry.registerComponent('AdditionalComponents', () => App); 

We will be using the index.js file found in the app folder to contain the code for the examples that we'll be building.

At the end of this step, we have an index.js file:

// AdditionalComponents/app/index.js 

import React, { Component } from 'react'; 
 import { 
} from 'react-native'; 
import styles from './styles'; 
export default class App extends Component { 
  render () {
