sending a javascript object through websockets with faye

WebSockets support sending and receiving: strings, typed arrays (ArrayBuffer) and Blobs. Javascript objects must be serialized to one of the above types before sending.

To send an object as a string you can use the builtin JSON support:

ws.send(JSON.stringify(object));

To send an object as a typed array you can use a javascript BSON library such as this one:

ws.send(BSON.serialize(object));

When you receive a WebSocket message you will need to deserialize it.

To deserialize a JSON string from a WebSocket message:

ws.onmessage = function (e) {
    var object = JSON.parse(e.data);
    ...
};

If you are using binary messages over WebSocket, then first you should set the binaryType attribute in order to receive all binary messages as typed arrays:

ws.binaryType = "arraybuffer";

Then the deserialization will look like this:

ws.onmessage = function (e) {
    var object = BSON.deserialize(e.data);
    ...
};

Here is a blog post about using BSON in Javascript;
