A Gorilla WebSocket implementation with support for rooms/channels.

• wsrooms(url) - connect to a wsrooms WebSocket server at url and return a root instance

• .send(event, payload, dst) - send payload of type event to dst; if dst is not specified or an invalid peer id then broadcast to all connected peers
• .join(room) - join room and return a room instance
• .leave() - disconnect from the WebSocket server
• .purge() - leave all rooms except the root room

• .send(event, payload, dst) - send payload of type event to dst; if dst is not specified or an invalid peer id then broadcast to all peers within this room
• .leave() - leave this room

When sending data, payload is always converted to an ArrayBuffer. In order to parse this data, the following utility methods come in handy:

• wsrooms.getStringFromCodes(array) - get a string from array of character codes
• wsrooms.getCodesFromString(string) - get an array of character codes from string

    "github.com/gojonnygo/wsrooms"

var index = template.Must(template.ParseFiles("index.html"))

func indexHandler(w http.ResponseWriter, r *http.Request) {
    index.Execute(w, nil)
}

func staticHandler(w http.ResponseWriter, r *http.Request) {
    http.ServeFile(w, r, r.URL.Path[1:])
}

func main() {
    wsrooms.Emitter.On("hello", func (conn *wsrooms.Conn, data []byte, msg *wsrooms.Message) {
        log.Println(msg)
    })
    http.HandleFunc("/", indexHandler)
    http.HandleFunc("/static/", staticHandler)
    http.HandleFunc("/ws", wsrooms.SocketHandler)
    log.Fatal(http.ListenAndServe(":8080", nil))
}

var socket = wsrooms('ws://localhost:8080/ws');

socket.on('open', function () {
    var room = socket.join('myroom');

    console.log('Socket opened.');
    room.on('joined', function (peerid) {
        console.log(peerid);
    });
    room.on('left', function (peerid) {
        console.log(peerid);
    });
    room.on('hello', function (data) {
        console.log(JSON.parse(wsrooms.getStringFromCodes(data)));
    });

});

    console.log('Socket error: ', err);
