API

Siggi relays JSON encoded messages between peers in the same room.

To join a room open a WebSocket and specifiy the room.

var socket = new WebSocket('ws://localhost:9000/socket?room=fancy-room-name');

To broadcast a message to all peers connected to the room, send a message without an recipient.

socket.send(JSON.stringify({
  type: 'hello',
  data: 'arbitrary data'
}));

To send a message to specific peer, add an recipient.

socket.send(JSON.stringify({
  type: 'hello',
  to: 'recipient-id',
  data: 'arbitrary data'
}));

The recipient will receive the following message.

{
  type: 'hello',
  from: 'sender-id',
  to:   'recipient-id',
  data: 'arbitrary data'
}
