JavaScript Lab January 18, 2016 Building Native Mobile Apps using Javascript with Titanium 

Fokke Zandbergen Developer Evangelist Appcelerator @FokkeZB 

Program 1. Appcelerator: More than Apps 2. JS2Native: No WebView 3. Titanium: SDK & Cross-Platform API 4. Alloy: MVC for Titanium 5. Hyperloop: Access any (3P) API in JS Slides will be linked from @FokkeZB tomorrow morning

 “#bar”: {
 color: “white”
 } Ti.UI.createFoo(); Ti.bar.createFoo(); require(“bar”).createFoo(); Alloy.createController(“foo”)
 .getView(); Alloy.createWidget(“foo”)
 .getView(); $.bar = Ti.UI.createFoo(); Ti.UI.createFoo({

 }); $.bar = Ti.UI.createFoo({

 }); 

A lote more.. • Platform specific code blocks and assets • Platform/Environment specific config file • Underscore + Moment.js: built-in libraries • Backbone.js: events, models and data-binding • Alloy Themes: Ideal for white label apps • Alloy Widgets: Re-use code across apps • …

 var blur = require('bencoding.blur'); var view = blur.createBasicBlurView({ blurRadius: 5, image: '/images/background.png' }); var window = Ti.UI.createWindow(); window.add(view); window.open(); How you used to extend Titanium 

Hyperloop for Windows var Window = require('Windows.UI.Xaml.Window'), TextBlock = require('Windows.UI.Xaml.Controls.TextBlock'), Colors = require('Windows.UI.Colors'), SolidColorBrush = require('Windows.UI.Xaml.Media.SolidColorBrush'); var text = new TextBlock(); text.Text = 'Hello, world!'; text.FontSize = 50; text.Foreground = new SolidColorBrush(Colors.Red); var window = Window.Current, window.Content = text; window.Activate(); 

 var Hyperloop = require("hyperloop"); var TiApp = require("TiApp"); var UIViewController = require("UIViewController"); var UILabel = require("UILabel"); var UIColor = require("UIColor"); var UIScreen = require("UIScreen"); var CGRect = require("CGRect"); var NSTextAlignment = require("NSTextAlignment"); var label = UILabel.initWithFrame(CGRect.Make(0, 0, UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height )); label.setText('Hello World!'); label.setTextColor(UIColor.redColor()); var viewController = UIViewController.init(); viewController.view.setBackgroundColor(UIColor.whiteColor()); viewController.view.addSubview(label); TiApp.app().showModalController(viewController, false); Hyperloop for iOS

Hyperloop for Android var TextView = require('android.widget.TextView'), Activity = require('android.app.Activity'), Color = require('android.graphics.Color'), RelativeLayout = require('android.widget.RelativeLayout'), Gravity = require('android.view.Gravity'), TypedValue = require('android.util.TypedValue'); var text = new TextView(activity); text.setText("Hello World!"); text.setTextColor(Color.RED); text.setTextSize(TypedValue.COMPLEX_UNIT_PX, 60); var layout = new RelativeLayout(activity); layout.setGravity(Gravity.CENTER); layout.setBackgroundColor(Color.BLACK); layout.addView(text); var activity = new Activity(Ti.Android.currentActivity); activity.setContentView(layout); 

var text = Ti.UI.createLabel({ text: "Hello, world!", font: { fontSize: 60 }, color: 'red' }); var window = Ti.UI.createWindow(); window.add(text); window.open(); Abstraction can be good
