Global data transfer objects in a crux app

[Roman Isitua <ro...@gmail.com>]

My application is  multi module and crux based. In my main module, I have a
class ConfigData that holds app configuration.  The ConfigData class is
declared in the crux beans.xml file.  This class is initialized during
application start up. A call to a web service fetches the data and
populates this class.

 Whenever the app switches modules from the main module (i.e. parent crux
module) to another module ( i.e. a child crux module), I notice that the
configData instance is null. This happens even when I have injected the
configData instance in the class that uses configData..

So my questions are:

1. How can an instance initialized in a parent crux module be referenced in
a child module ?

2. How can I share data between modules in a crux app ?


Regards,

Compile everything into a single app. I have a number of swcs for pieces of my projects, but the final app is a single compile. I have found very little reason to use modules in Royale (even for an app with hundreds of thousands of lines of code). In Flash, each component added considerably to the size of your app. In Royale, there’s very little bloat when adding UI. I think you’ll find the whole Royale application including all the “modules” will be considerably smaller than just your main Flex application in Flash. Using modules will probably just make your life more difficult and cause your app to load slower.

Release build minifies all the Javascript into a single file and often renames things. You can control how much renaming is done using the compiler options: https://apache.github.io/royale-docs/compiler/compiler-options

You can run it, but it will be MUCH slower to load. You need to load each as and mxml file as a separate js file. It’s good for debugging because you can see exactly where the code is, but not so good for performance.

I have started development using crux with modules. My current observation
is that crux initialize classes defined in the beans.xml of the child
module.


To share data between modules e.g. parent and child are recently discovered
the local shared object functionality.  I tried it, it works.

You comments raises a few concerns for me namely:

1. Are you suggesting I should not make the app multi module ? If yes what
is the alternative ?

2. What's the difference between debug and release builds ?


3. Can I run the app in production using the debug builds ? The app will be
in testing phase and beta phase for a while before being released.

It is fair to say that Crux has not been tested with modules. But also
current modules support is not yet reliable and needs additional work
(community contributors are definitely welcome) - they might work for debug
builds, but they are not currently a working solution for release builds.
