Where’s alloy? JavaScript Native Titanium Alloy 

“An alloy is a mixture or metallic solid solution composed of two or more elements” “Alloys usually have different properties from those of the component elements.” What’s an alloy?

Alloy Views · Markup • XML elements corresponds to Ti.UI objects • Require other views and widgets • id for access from controller • platform and formFactor conditions • platform specific folders • bind events to controller methods • bind markup to models via generated controller code DEMO 

Alloy Controllers • $.someID to access view elements • exports.baseController to inherit a parent controller • platform (OS_) and environment (ENV_) constants • Passing arguments: var args = arguments[0] || {}; • Alloy.Globals namespace • Require libraries from ‘lib’ folder DEMO 

Alloy Models • Abstracted BackboneJS, but still a must-read • “Collections keep models in memory & synced to a store” • Database > Connection > Result > Row • Easily extend BackboneJS classes • SQL, properties and localStorage sync adapters • Migrations • Model-View binding DEMO 

Alloy Views · Styles • CSS like JSON style • #ID over .class over element • Titanium constants like Ti.UI.TEXT_ALIGNMENT_LEFT • Alloy.Globals and Alloy.CFG for expressions etc. • platform and formFactor conditions • platform specific folders DEMO 

Alloy Views · Themes • Overwrite assets • Overrule styles • Global app.tss • platform and density specific (asset) folders • config.json environment/platform dependent selection DEMO 

Alloy Widgets • Self-contained Alloy components almost like mini-apps • controllers, views, styles, assets, libs • models and theming coming • Require like views or use • Use widgets in widgets • Marketplace and NPM-like distribution coming DEMO 

Alloy Optimization • From app to Resources folder • Platform specific folders, conditional styles, conditional JS unused libraries and builtins all stripped out! • UglifyJS for optimal speed and compactness • Build configuration file for pre and post compile tasks DEMO 

How to get started with Alloy? • Get Titanium Studio 3.x from www.appcelerator.com • Follow me @FokkeZB or fokkezb.nl for upcoming: • Slides • Code shown today • Alloy Quick Start and links to various resources
