Akka.js status

AKKA-ACTOR

• actor/
• dispatch/
• event/
• pattern/
• routing/
• serialization/
• util/

TODO

• allow ovewriting of context by rewriting IR in ActorCell.scala
• remove dependencies from akka.util.JS*
• Strategies are mostly missing
• add support for Workers + routing in ActorPath (partial, will be refactored in akka-remote)
• IMPORTANT refactor out Java API, maybe with a mixin? We could share this approach with JS (see Higher level JS binding #6) and provide Java || JS api if we're calling from Scala or Scala.js
• port typesafe.config.Config (it's 100% Java, so we can't cross-compile. alternatives? see @mfirry 's suggestion in port typesafe.config #5 )
• sun.misc.Unsafe (stub implementation vs mixin with traits JS/JVM specific methods?)
• JVM data structures (see Missing data structures #8)

DONE

• move JSMap to TreeMap
• some System.getEnv and System.getProperty calls to remove (eg: ActorSystem.scala)
• mailboxTypes are missing
• refactor out references to Thread (eg: Thread.currentThread().interrupt())
• implement event/ (and therefore Logging)
• clean up setActorFields in Actor.scala
• remove Java imports
• remove Java (ThreadLocal, etc) from ActorCell.scala and add lookupAndSetField
• MalformedUrlException in ActorPath
• Deployer doesn't exist yet
• ActorFor in ActorRefProvider.scala
• Implement constructor for Props
• some code depends on DynamicAccess, it needs to be refactored out
• terminationCallbacks in ActorSystem
• fix override def in the EventLoopScheduler (they override final methods, had to fix by hand)
• dispatch/AbstractDispatcher.scala contains some thread-specific logic, refactor it out?

AKKA-REMOTE

Currently blocked by:

• Lack of a pickling library capable of serializing Any (scala pickling should help solve the issue: @phaller @heathermiller )
• Reflection in Scala.js (partial support being discussed here)

[andreaTP]

a POC with working serialization is already here.
This must now be exploited in a full remote working.
Referring to branch remote.

Hi @andreaTP, thanks for this excellent work! Is this status up to date as of January 2019? What's the overall status of this project?

[andreaTP]

Hey @shafqatevo , thanks for the question and I will be happy to follow up more exaustively in the gitter channel!
Overall the project is in great shape and I'm able to update it to stay in sync with Akka releases with a really low effort ( just released 1.2.5.19 ).
From the initial plans the remoting part is still lacking. But the core is pretty stable and even performant.

Consider that it is integrated in the official Akka documentation and it has been used by several speakers to show Akka capabilities in scalafiddle.

[shafqatevo]

Great!

Can you please elaborate what capabilities we would miss as developers until remoting is completed?

Can we currently use web workers as actors?

[andreaTP]

@shafqatevo I will be really happy to elaborate around the topic in the gitter channel. Sorry but this is not the right space to chat. Thanks for the interest in the project!!!
