React Native By Example

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.

The Navigator component works a bit differently from its native iOS component, but it's still very powerful to work with. One of the changes with using Navigator is that your routes should be explicitly defined. We can do this by setting up an array of routes and rendering a specific scene based on which route we're accessing. Here's a sample:

export default class Tasks extends Component { 
  render () { 
    const routes = [ 
      { title: 'First Component', index: 0 }, 
      { title: 'Second Component', index: 1 } 

Create a routes array, as shown in the preceding code.

You might notice that we are explicitly defining our routes from the beginning, setting up an initial route and then passing in props to each route's component here:

    return ( 
        initialRoute={{ index: 0 }} 
        renderScene={ (routes, navigator) => 
        this._renderScene(routes, navigator) } /> 

The route object passed in to _renderScene contains a passProps...
