Easy to use

Server:

    var guestCounter = 0;
    io.set('authorization', function (handshake, accept) {
        return accept(null, handshake.nickname = 'Guest'+ ++guestCounter);

Client:

    var socket = io.connect('http://localhost');

        messages.append(user+'> '+message);
    });

socket.io namespace compliant

Server:

    require('chat.io').createChat(io.of('/chat'));

    var guestCounter = 0;
    io.of('/chat').authorization(function (handshake, accept) {
        return accept(null, handshake.nickname = 'Guest'+ ++guestCounter);
    });

Client:

    var socket = io.connect('http://localhost/chat');

Channels

Client:

    // beeing notified
    socket.on('join', function (user) {
        message.append(user + ' joined your channel.');
    });

    // joining
    socket.emit('join', 'aChannel', function (err) {
        if (err) messages.append('Error joining aChannel: ' + err);
    });

Whisper

Client:

    // receiving
    socket.on('whisper', function (user, message) {
        messages.append('<i>from '+user+'> '+message+'</i>');
    });
    
    // sending
    socket.emit('whisper', 'aUser', 'Hello, aUser!', function (err) {
        if (err) messages.append('Error whipering aUser: '+err);
    });

Kicking

Server:

    chat.on('connection', function (nickname) {
        if ('badyGuy' === nickname)  {
            chat.kick(nickname);
        }
    });

Channel permission system

Server:

    // deactivate channel switching
    chat.set('channel join permission', false);

    // permission callback
    chat.set('channel join permission', function (user, channel, allow) {
        if ('operator' === user) {
            return allow(true);
        }
        if ('secret' === channel) {
            return allow(false);
        }
        return allow(true);
    });

Server messages

Client:

    socket.on('message', function (message) {
        messages.append(message);
    });

Server:

    // global messages
    chat.sendSystem('Server shutting down in 10 minutes.');

    // channel messages
