Download as PPT, PDF4 likes800 views
The document discusses Jesse Warden's background and expertise in Flex, Flash, and Robotlegs. It provides an overview of the Gaia framework for building Flash websites, how it works with the Robotlegs MVCS framework, and some best practices for using them together. Key features of Gaia and Robotlegs like dependency injection, events, models, commands, and services are summarized.

Robotlegs on Top of Gaia
- 2. Who Jesse Warden Flex & Flash Consultant Career: Director, Flash, Flex Education: Art, Self-Taught Coder
- 3. Robotlegs/Gaia Gaia Robotlegs Using Them Together + = Hot Dog!
- 4. Why? Flash Sites: Scaleable Mess Flex Sites: Re-invent the wheel ...Badly.
- 6. Gaia Framework & Toolset for Building Flash Websites Inspired by Ruby on Rails
- 7. Gaia Inventor Steven Sacks Gaia Inventor stevensacks.net Twittah: stevensacks
- 8. Industry Tools SWFObject SWFAddress TweenLite Thunderbolt
- 9. Example Sites Client Sites Mercedes, Disney, Rolling Rock, Honda, Burn After Reading, Keith Urban, Dermalogica, Absolut, Star Trek Movie, Electronic Arts: Tiberium, NIP/Tuck, 180 Energy Drink
- 10. Site XML <site title="Gaia Scaffold Site"> <page id="index" src="index.swf"> <page id="nav" src="nav.swf"> <page id="home" src="home.swf" title="Home"> <asset id=”music” src=”rock.mp3”/> </page> </page> </page></site> </page> </page> </page></site>
- 11. Scaffolding
- 13. Transitions transitionIn(); transitionOut(); transitioninComplete(); transitionOutComplete();
- 14. Flows Normal Preload Reverse Cross
- 15. Depth
- 16. Assets
- 17. Preloading multiple Files, Byte Accuracy Override Runtime API Pre-loaders for Pages Pre-loaders for Assets
- 18. Other Features SEO Scaffolding (yes, it works) DEEPlinking API on top of SWFAddress Bindings support in Site.xml
- 19. Gaia Bread and Butter
- 20. Robotlegs MVCS Framework ActionScript 3
- 21. Robotlegs Pure AS3 = Yes Flex = Yes AIR = Yes Flash = Yes (CS4/CS5)
- 22. Robotlegs Shaun Smith Robotlegs Inventor Shaun.boyblack.co.za Twittah: darscan
- 23. Robotlegs Comes with a Reference Implementation (MVCS) Robert Penner’s “Signals” Elad Elrom’s “Passive View Example” AsyncCommand
- 24. Dependency INjection The New “ New ” All you need to know: [Inject] SWiftSuspenders SmartyPants IoC GUICE : A Different Java Spring
- 25. Dependency Injection Solves PureMVC’s Casting Problem var myView: viewObject as MainView; var proxy:MyProxy = facade.retreiveProxy(MyProxy.NAME) as MyProxy; Easier to code to Interfaces
- 26. DI Example private var proxy:MyProxy; var proxy:MyProxy = facade.retreiveProxy(MyProxy.NAME) as MyProxy; trace(proxy.myVO); --------------------------- [Inject] public var model:MyModel trace(model.myVO);
- 28. Events Communications Through Events
- 29. Event Gotchas Tons Sub-Systems More Events > More properties
- 31. View GUI Form Chart Video Player List of Images
- 32. Dumb View Dumb 2 things Accept Data Dispatch User Gestures
- 34. ValueObject HOld “Value” 2nd Most Valuable Class Strongly Typed Can Differ From Server to help GUI
- 35. VO Gotchas To Build yerself... ...or have a Factory do it constructor Params foil Serialization Use Optional Values if you must It changes, affects Entire App
- 36. Robotlegs Context Mediator Services Model Command Actor (Base Class)
- 38. Context Initialize Framework Event Bus Multiple Contexts for Modular Development
- 39. Actor Base Class for Model and Service Has Context Injected Base Class to communicate to the Framework
- 41. Mediator Mediator Pattern View Communicate w/ Framework 1 View per Mediator Keeps Framework out Not all views need Mediators
- 43. Service Retrieve and/or Send Data Remote and/or Local Services Parse Data to VO’s Dispatch Success or Failure Don’t Listen to Framework Events Great Unit Test Candidates
- 44. Service Practices Doesn’t Store Data Dispatch Event, has Data in It Extend Actor Store’s Data Dispatch Event, NO Data in It Extend EventDispatcher
- 45. Service Gotcha’s Foreign Data FActories : #1 Source of Bugs Compiler Doesn’t Help you Manual Timeouts Explode Early
- 47. Model(s) Observer Pattern Stores Global Data Usually Wraps a VO Doesn’t Listen for Framework Events Dispatches Data Changes Persists Extends Actor
- 48. Model(s) Re-Factor to: Data needs to persist 1> Mediator/Command Use Data
- 50. Command Command Pattern Controller Work DRY Re-Factor To Doesn’t Listen to Framework Events
- 51. Command Example Login Form Update Profile Edit Server Data
- 52. User Gestures Command’s are Usually User Gestures Login, Logout, SaveUser AddTag Save
- 53. Command Pro’s DRY Centralized Logic Data Problem = 2 places to look Service Command Not Hunting Through Mediators RAD (Rapid Application Development)
- 54. COmmand Con’s Code Bloat Early in Project Handling Context Sensitive Data? ...2 Commands 20 User Gestures = 40 Commands Commands for Everything
- 56. AsyncCommand Asynchronous Command Why? Java/C/C++ Devs Invented Command Pattern Blocking Language Executes Server Request and Code pauses
- 57. AsyncCommand ActionScript is not Blocking It is Asynchronous Sometimes things need to wait To wait, they need context To have context, they need to exist Commands die immediately
- 58. AsyncCommand AsyncCommand’s do not Block You Control when they die You can handle Server responses with Context React & Respond w/ Less code fork to call other Commands
- 59. Gaia + Robotlegs Gaia builds yer Site Robotlegs Handles: Business Logic Application Logic +
- 60. Why? Agency Shields from Ever Changing client Visuals View Changes, App/Biz Logic Doesn’t Dev Don’t Break Gaia’s modules RAD & Scaleable
- 61. How? Export SWC “Magic Checkbox”
- 62. Step by Step Setup Gaia Project Register Context in Main.as Page or child View implement Interface Register Interface for Mediator
- 63. Rules n’ Gotchas Interface for Bridge Pattern Gaia Pages use Bridge Pattern Not all Gaia Pages need a Mediator
- 64. Conclusions Gaia is the Foundation for Site Robotlegs Handles Biz & App Logic Together, they Build a Scaleable & Flexible Site
