Actor system for Scala.js

Actor system for Scala.js

This project aims at providing an actor system for Scala.js, featuring:

• Supervision
• (Almost) transparent collaboration with actors in an Akka-based backend
• Transparent collaboration with actors in several Web Workers

It is currently a prototype, working well but still in a rough shape. Hence, it is not published anywhere yet.

Build it and try the examples

To build the libraries, use

> package

in an sbt console.

Fault-tolerance example

The fault-tolerance example is taken from Akka's documentation and showcases supervision, death watch notifications and the like.

Build it with:

> faultToleranceExample/fastOptJS

then open examples/faulttolerance/index-fastopt.html in your browser and look at the Web console for the output.

Web Workers example

The Web Workers example demonstrates the communication between Web Workers.

Build it with:

> webworkersExample/fastOptJS

then open examples/webworkers/index-fastopt.html in your browser and look at the Webconsole for the output.

Chat example (with client-server communication)

The Chat example is a full-stack Play/Akka/Scala.js application where client and server communicate transparently between Akka/JVM and "Akka/JS".

Build the client then run the server with:

> chatExampleScalaJS/fullOptJS
> project chatExample
[scalajs-actors-examples-chat] $ run

then navigate to http://localhost:9000/opt with your browser. To have some fun, open multiple tabs (or multiple browsers) and start playing with the chat.
