Parsley: Your Favourite Herb?

I’ve just started looking into Parsley: http://www.spicefactory.org/parsley/ First thought: version 2 is exactly what I’ve been trying to build with RobotLegs.

RobotLegs AS3: System/Context Event Flow

RobotLegs AS3 is a Dependency Injection Driven MVCS Framework for Flash and Flex inspired by PureMVC. Actors may be dependent on actors below them in the diagram, but should not be dependent on anything above them. Commands, Services and Proxies may dispatch system events, but should never listen for them. Mediators may both dispatch and listen for system events.

Constructor Injection vs Setter Injection

Constructor injection is theoretically superior: Constructor Injection vs Setter Injection Constructor vs Setter Injection – Constructor is Better Setter injection versus constructor injection and the use of required Before I built RobotLegs I was sold on constructor injection. My prototype, however, used SmartyPants-IOC which lacked constructor injection, so I bit my lip and used setter injection. In practice I found that often, especially with framework actors, it was incredibly convenient.

Another Architectural Framework, But Why?

The State Of The Game There are some great Flash and Flex application frameworks out there right now. Mate, Swiz and PureMVC (update: and Parsley!) stand out. The authors of these frameworks realized that the Flash Platform is different enough to the JVM to warrant a fresh approach to application design.

RobotLegs AS3: A DI Driven MVCS Framework for Flash & Flex – Inspired by PureMVC

Want a framework like PureMVC but without Singletons, Service Locators, or casting? Perhaps one with Dependency Injection and Automatic Mediator Registration? Well, you might enjoy RobotLegs AS3: yet another lightweight micro-architecture for Rich Internet Applications.

AS3 Dependency Injection and [Autowire]

Warning: This is long and probably VERY boring.. unless you are an AS3 junkie, and you’re interested in so called “lightweight micro-architectural frameworks” for Flash and Flex. A couple of weeks ago I played around with Mate and Swiz. I already knew a little about Dependency Injection (in theory anyway), but playing with those two frameworks really drove the point home: applications are potentially MUCH easier to write, and much more flexible, when you take advantage of Dependency Injection.

Flexible RIA Architecture: PureMVC and Mate

I’ve been using PureMVC for my Flash/Flex applications for quite a while now, and have generally found it to work quite well. Besides the obviously annoying abundance of boiler-plate code, it does a decent job of separating concerns, and has helped me to build better applications. Lately, however, I’ve been building an application for which PureMVC has turned out to be a pretty poor fit. The term that some people have used to describe this kind of application is “Document-Based”.

Interactive Application Architecture

Just in case you thought that there was a clear cut definition of MVC: http://ctrl-shift-b.blogspot.com/2007/08/interactive-application-architecture.html And if you are considering using Cairngorm for your next project, give this a read (especially the comments, all of them): http://blog.iconara.net/2008/04/13/architectural-atrocities-part-x-cairngorms-model-locator-pattern/
