usage

Define a nice way to talk to your plugin by extending Janus.Plugin, e.g:

MyRecordPlugin = Janus.Plugin.extend({

    initialize : function(attributes, options) {
        this.set("name", "janus.plugin.myrecord");

        options = options || {};

        var media = {
            data: true
        };
        if (options.publish) {
            _.extend(media, {
                audioSend: true,
                videoSend: true
            });
        }
        if (options.subscribe) {
            _.extend(media, {
                audioRecv: true,
                videoRecv: true
            });
        }
        _.extend(this.get("media"), media);
    },

    publish: function(stream, options) {
        var body = {
                request: "join",
                type: "publisher",
                name: stream,
            };

        _.extend(body, _.pick(options,
                "record",
                "record_rotate_freq",
                "audio",
                "video",
                "bitrate"
            ));

        this.set("stream", stream);

        return this.sendMessage(body);
    },

    subscribe: function (name, publisher, options) {
        var body = {
                request: "join",
                type: "subscriber",
                name: name,
                publisher: publisher,
            };
        _.extend(body, _.pick(options, "paused"));
        return this.sendMessage(body);
    },

    configure: function (options) {
        var body = {
                request: "configure"
            };
        _.extend(body, _.pick(options,
            "record",
            "record_rotate_freq",
            "audio",
            "video",
            "bitrate",
            "paused"
        ));
        return this.sendMessage(body);
    },

    sessions: function () {
        var body = {
            request : "list"
        };
        return this.sendMessage(body);
    },

    leave: function () {
        var body = {
            request : "leave"
        };
        return this.sendMessage(body);
    }
});

then create a Janus.Session:

var janusSession = new Janus.Session({}, {
    urlRoot: "ws://127.0.0.1:8188",
    secret: "janusrocks",
    iceServers: [{
        "url":"stun:stun.l.google.com:19302"
    }],
    pcConstraints: {
        "optional": [{"DtlsSrtpKeyAgreement": true}]
    }
});

attach your plugin to it:

var janusPlugin = new MyRecordPlugin(null, {
    publish: false,
    subscribe: true
});

janusSession.connect()
    .then(function () {
        return janusPlugin.attach(janusSession);
    })
    .then(function () {
        return janusPlugin.createPeerConnection();
    })
    .then(function () {
        return janusPlugin.createOffer();
    })
    .then(function () {
        return janusPlugin.subscribe("subscriber-id", "publisher-id");
    });

and use it:

janusPlugin.configure({
    audio: false,
    video: true,
    bitrate: 1024
});
