Question 1

Is PureMVC still relevant for new AS3 projects in 2024?

Accepted Answer

Due to the decline of Flash and ActionScript 3, PureMVC is primarily useful for maintaining legacy codebases. For new projects, consider modern frameworks unless specifically targeting AS3 platforms like AIR or older Flex applications.

Question 2

How to set up PureMVC in a Flex application?

Accepted Answer

Include the framework source files in your project, then initialize the Model, View, and Controller singletons in your main application class. Refer to demos like 'Cafe Townsend' or 'Employee Admin' for complete examples with Flex-specific integrations.

Question 3

PureMVC vs Cairngorm: which is better for large Flex applications?

Accepted Answer

PureMVC offers a more lightweight and unopinionated classic MVC approach, while Cairngorm is more prescriptive with a stronger focus on Flex patterns. Choose PureMVC for flexibility and Cairngorm if you prefer Adobe's official framework with tighter Flex integration.

Question 4

Can I use PureMVC with Adobe AIR for mobile apps?

Accepted Answer

Yes, PureMVC is compatible with AIR, and demos like 'CodePeek' and 'RSS Headlines' show how to structure AIR applications. However, note that AIR itself is a legacy technology with limited modern mobile development support.

Question 5

What are the differences between PureMVC Standard and MultiCore versions?

Accepted Answer

Standard uses Singleton patterns for core actors and doesn't support modular programming, while MultiCore uses Multiton patterns to allow multiple isolated MVC cores, making it better for complex, modular applications.

Question 6

How does PureMVC handle asynchronous operations?

Accepted Answer

Through utility libraries like Async Command, which provides patterns for managing async tasks within the MVC structure, ensuring commands execute in order and handle errors without breaking the application flow.

Question 7

Is there dependency injection support in PureMVC?

Accepted Answer

No, PureMVC does not natively support dependency injection; it relies on Singleton patterns for core actors. For DI, you'd need to integrate external libraries or adapt the framework, which can add complexity.
