Listen to All Emitted Events in Node.js

Question

In Node.js is there any way to listen to all events emitted by an EventEmitter object?

e.g., can you do something like...

event_emitter.on(\

You might want to look into RPC modules for node.js. If I am not mistaken the Dnode RPC module has an chat server/client example similar to what you are trying to do. So you could either make use of their module or copy what they are doing.

In brief the example shows a server which on connection creates listeners for all the server events from the connected client. It does this by simply iterating over a stored list of event names.

var evNames = [ 'joined', 'said', 'parted' ];

con.on('ready', function () {
    evNames.forEach(function (name) {
        emitter.on(name, client[name]);
    });
    emitter.emit('joined', client.name);
});

This code is clever because it automatically calls a remote procedure call on the client associated with the event when the event is emitted.
