Slides from a talk I gave at Dot Brighton

1. RL2
ActionScript Application Framework

3. RL1 Recap
Dependency Injection
Commands
Mediators
https://github.com/robotlegs/robotlegs-framework/tree/master 3

4. RL2
As above, but with:
A fluent API
Extensions (opt-in)
Bundles (presets)
Configs
Logging (built-in)
Module autowiring
https://github.com/robotlegs/robotlegs-framework/tree/version2 4

5. Dependency Injection
https://github.com/tschneidereit/SwiftSuspenders/ 5

6. Swiftsuspenders 2
injector.map(IService).toValue(service)
injector.map(IService).toType(SomeService)
injector.map(IService).toSingleton(SomeService)
injector.map(SomeService).asSingleton()
Faster
Local vs shared scopes
Hard vs soft mappings
https://github.com/tschneidereit/SwiftSuspenders/ 6

7. Context & Startup
framework/readme-context.md 7

8. context = new Context()
.extend(MVCSBundle)
.configure(MyAppConfig, this);
No more extend and override
Opt-in extensions
Convenient, shareable bundles
Conventions for configuration
Consolidated startup process
framework/readme-context.md 8

9. Commands
extensions/eventCommandMap 9

10. eventCommandMap
.map(SomeEvent.EVENT, SomeEvent)
.toCommand(MyCommand)
.once();
extensions/eventCommandMap 10

11. Mediators
extensions/mediatorMap 11

12. mediatorMap
.map(SomeType)
.toMediator(SomeMediator)
Can map to interfaces and abstract types
Possibly many mediators per view
Nested stage listener optimisations
extensions/mediatorMap 12

13. Configs
framework/readme-context.md 13

14. context = new Context()
.extend(MVCSBundle)
.configure(MyAppConfig, this);
framework/readme-context.md 14

15. class ViewConfig
{
public function ViewConfig(mediatorMap:IMediatorMap)
{
mediatorMap.map(SomeView)
.toMediator(SomeMediator);
}
}
framework/readme-context.md 15

16. class MyModuleConfig implements IConfig
{
[Inject]
public var mediatorMap:IMediatorMap;
public function configure():void
{
mediatorMap.map(SomeView)
.toMediator(SomeMediator);
}
}
framework/readme-context.md 16

17. Extensions
extensions 17

18. public class EventCommandMapExtension
implements IExtension
{
public function extend(context:IContext):void
{
context.injector
.map(IEventCommandMap)
.toSingleton(EventCommandMap);
}
}
extensions/eventCommandMap 18

19. Extensions are installed immediately:
context.extend(MyExtension)
~=
new MyExtension().extend(context)
extensions 19

20. Bundles
bundles 20

21. context = new Context()
.extend(MVCSBundle)
.configure(MyAppConfig, this);
bundles 21

22. public class MVCSBundle implements IBundle
{
public function extend(context:IContext):void
{
context.extend(
ModularityExtension,
EventCommandMapExtension,
... etc ...
MediatorMapExtension,
StageSyncExtension);
context.configure(ContextViewListenerConfig);
}
}
bundles/mvcs 22

23. Bundles are installed immediately:
context.extend(MyBundle)
~=
new MyBundle().extend(context)
bundles 23

24. Bundles vs Extensions
extensions 24

25. An extension integrates a single utility or library with a
Robotlegs context
A bundle installs a selection of extensions and
configurations into a Robotlegs context
extensions 25

26. Logging
framework/readme-logging.md 26

27. Lightweight logging system built in: context.getLogger(MyClass)
Optional logging extensions
LoggingExtension: allows you to [Inject] public var logger:ILogger;
InjectorLoggingExtension: logs injection events (not 4 production!)
TraceLoggingExtension: simple trace log target
extensions/logging 27
