A WebRTC signaling server with some other niceties that allow for smooth sailing on the Grooveboat.

Event flow

As of right now, here's how this event flow should work:

*client connects*
server -> welcome
client -> joinRoom
server -> roomInfo

...
*client is messing around*
client -> ping
server -> pong

*client decides they want a nick change*
client -> setName
server -> changeName (to all client except for the sender)

...
*another client connects elsewhere*
server            -> peerJoined
client (new)      -> sendTo (the new client begins attempting to peer with users)

*another client leaves*
server -> peerLeft

*client sends a chat*
client -> sendChat
server -> chat (to all client except for the sender)

Event documentation

Server events

These are sent to the server by the client.

setName

Changes a client's name

Send data:

{
    "e":   "setName",
    "name": "newName"
}

Sends a chat message to all other clients in the current room

Send data:

{
    "e":   "sendChat",
    "msg": "message text"
}

joinRoom

Send data:

{
    "e":    "joinRoom",
    "roomName": "room name"

}

ping

    "e": "ping",
}

sendTo

Sends a message to another peer (by uuid).

Send data:

    "e":   "sendTo",
    "to":  "peer uuid"
    "msg": { ... }
}

Client events

These are events that are received by the peers.
