Bind event to all socket.io connections

Question

Bind event to all socket.io connections

I know it's possible to emit events to all connections using io.sockets.emit('some event'), but can I also globally bind events to all present and future connections? Would probably look like

io.sockets.on('feedTheDog', function (data) {
    // Someone told me to feed the dog..
});

Also, can I remove event listeners with .removeAllListeners() with Socket.IO?

node.js
socket.io

Answer 1

I also don't think you can bind events to future connections, but yes, you can use removeAllListeners with socket.io. They ported node's event emitter to the browser, so it's exactly the same api there. Here's the code for it: https://github.com/LearnBoost/socket.io-client/blob/master/lib/events.js

Answer 2

You can use socket.io-events and attach middleware functions to handle messages for all socket connections, without actually attaching a handler to a socket.
