Titanium Desktop Intro
Titanium is an open source framework that allows developers to build native desktop apps using web technologies like HTML, CSS, and JavaScript. It provides APIs for common desktop tasks and supports Windows, Mac OS X and Linux. The demo app shown takes a screenshot using the Titanium.Desktop.takeScreenshot API and displays it, illustrating how Titanium can be used to create basic desktop applications.

- 4. What is Titanium? •An open source framework for building native apps using web technologies • Titanium Desktop: Windows, OSX, Linux • Titanium Mobile: iPhone, Android http://appcelerator.com http://github.com/appcelerator @appcelerator #titanium_app on irc.freenode.net
- 5. Motivation • Single SiteBrowsers (Fluid, Prizm) • Adobe AIR • Cross platform GUI toolkits (Qt, wxWidgets, XUL, GTK) • Dynamic Languages (Ruby, Python, Javascript) • Binding layers (Jython, Rhino, JavaScriptCore) • Next gen web tech: HTML5, Gears, CSS3 • ... And lots of caffeine!
- 6. Titanium Desktop • UI with HTML5, CSS, Canvas. The best of the open web. • Support for Javascript, Ruby, Python (PHP coming soon) • Languages can be intermixed automatically. • Native desktop functionality at your fingertips. • Titanium.* APIs are available in all languages • Windows (XP/SP2 -> 7), OSX (10.5->10.6, Universal), Linux (Debian based distros, Fedora, SuSE)

- 8. The Desktop Runtime • Fully configurable distribution options: • “Bundled” : Runtime is packaged with your app, no seperate installer • “Network Install”: A native installer downloads dependencies on demand • Remove modules you don’t need to cut down on binary size • Reuse the runtime already on the user’s machine • Runtime size: OSX: ~17MB, Win32: ~15MB

- 12. Database API Synchronous andAsynchronous (HTML5) APIs
- 13. Process API Launch processes,read/write from pipes
- 14. And much more.. • Web Workers: Multi-threading for Javascript • Desktop: Take screenshots, open URLs, applications • Comprehensive language support: • Javascript (WebKit / close to trunk -- blazing fast) • Ruby 1.8.6 (1.9 with GVL coming soon) • Python 2.5.4 (2.6 coming soon) • PHP 5.3 (in development) • Lua (in development) • C/C++ Native bindings • Java / C# planned post-1.0

- 16. Titanium Developer • Usedfor creating, managing, packaging and testing your native apps. • Requires sign-up for Appcelerator Network (forum support, e-mail list, other services) • Is actually a Titanium app!
- 17. Obligatory “Hello World” Usingthe sandbox to quickly test and run code
- 18. Screengrabber: Our firstapp • An app that takes a screenshot, and shows it to the user • App walkthrough: • Create the project in Developer • Overview of config files, manifest, app layout • Quickly roundtrip prototype, show off debugging, etc
- 19. Step 1: Configuration • $ROOT/tiapp.xml • Configure Windows, and their properties
- 20. Step 2: HTML,CSS, JS • clean out $ROOT/index.html • make a JS script, a CSS stylesheet
- 21. Step 3: Writethe JS • APIs we need from Titanium: • Titanium.Desktop.takeScreenshot(“path/to/file”) • Titanium.Filesystem.getFile() / getDesktopDirectory()
- 22.
- 23. Packaging • Once your app is written, you can use our cloud services to package and distribute your app. • Automatically packages with the config you specify, for the platforms you want to support • Built-in analytics to track who’s using your app, downloads, etc
- 24. Wrapping it up • Current release: 0.6 • 0.7 scheduled for end of Sept., 1.0 GA soon after • Come visit IRC for help, or to chat us up • #titanium_app on irc.freenode.net • Extra credit: using Python, Ruby during the hack session • And now, Lunch!
