kevoree-comp-wsmsgbroker

Starts a WebSocket server using dictionary attributes port & port

Usage

Add WSMsgBroker into a JavascriptNode, then set its port & path (optional) attributes.
Deploy your model, and that's it! You have a running WebSocket server listening on 0.0.0.0:<PORT>/<PATH>

Protocol

The server expects received messages to be JSON-encoded and to respect this protocol:

• register: Register a new client

  {
    "action": "register",
    "id": "YOUR_CLIENT_ID"
  }

The uniqueness of the IDs must be handled by the clients otherwise the server will just replace the old client-id.

• send: Send a message to a client (or multiple clients)

  {
    "action": "send",
    "dest": "SOME_CLIENT_ID",
    "message": "some message"
  }

or

  {
    "action": "send",
    "dest": ["CLIENT_ID0", "CLIENT_ID1", "CLIENT_ID2"],
    "message": "some message"
  }

msg.dest can be a string or an array of strings
