[Question] can this be used for browser plugins?

[domdorn]

I'm currently developing a browser plugin for firefox.
As firefox (as well as chrome, etc.) has different scopes for the DOM of normal pages and the DOM accessed by the plugin, the plugin can only interact with the page through message passing (so no invocations on objects).. basically a perfect use case for Akka(.js).

Is it possible to spawn an ActorSystem in the scope of the page and one in the scope of the plugin and let them communicate?

so my current approach would be something like this.. not sure if that actually works

1. handle the actual tab
   1a) create a script that loads the scala.js and akka.js dependencies
   1b) create a script that creates an ActorSystem('akkabrowser') and bind it to something like window.akka.akkabrowser .
   1c) do a

document.addEventListener('akkabrowser', function(e) { 
val message = e.detail
ActorRef(message.destination).forward(message.payload, message.sender)(window.akka.akkabrowser)
})

2. handle the foreground script in the extension
   2a) create a script that creates an ActorSystem('akkapluginfe') and bind it to something like window.akka.akkapluginfe
   2b) do a

document.addEventListener('akkapluginfe', function(e) { 
val message = e.detail
ActorRef(message.destination).forward(message.payload, message.sender)(window.akka.akkapluginfe)
})

3. handle background scripts in the extension // TODO ..
4. create some code similar to akka-remote that transforms a non-local message to something like

val envelope = ....
val targetActorSystem = extractActorSystem(envelope.destination)
val customEvent = new CustomEvent(targetActorSystem, {detail: {
  destination = envelope.destination
  payload = envelope.message
  sender = createAbsoluteSender(envelope.sender)
}}
document.dispatchEvent(customEvent);

What do you think?
