wss.clients
will always be the list of current clients. There's no such thing as a session which lives beyond an actual connection for WebSockets, so if you need to recognize the same client over and over again, you'll have to rely on parsing incoming cookies - or an initial handshake.
Similarly there's no such thing as an id - but neither should there be. If your application requires an id, you can easily add it as you show above. It makes perfect sense.
Regarding some recipes you are absolutely right. Some time should be spent writing documentation for different scenarios. I'll bring that into consideration for future versions!

@einaros Any progress on this?

Thanks. That's good to know. I'm working a slightly higher level JSON-based communication protocol to realize realtime applications. Very minimal somewhere between RPC and plain messages, with a straight-forward interface. :) I'll let you know once a working prototype is ready. I'd be interested in what you think. I could cover some by-example documentation by describing how I solved my problem using the ws
module.
In order to do a reverse lookup by client-id I need to pollute the ws object, which is not exactly elegant. So I wonder if you'd consider assigning unique client-ids natively (just a counter would be fine). Maybe this makes sense to add to ws directly, shouldn't hurt too much and could be useful in general. What do you think?
// Register client on connect
openSession: function(ws) {
ws.id = this.numClients += 1;
this.clients[ws.id] = ws;
},
// Unregister client on disconnect
closeSession: function(ws) {
delete this.clients[ws.id];
},

I'll consider that for the next version :) Shouldn't be a problem.

Thanks. :)

I'm doing something very similar, than the example above, just instead of storing a meaningless id, I use the sessionID provided by Express (and then I can do something like clients[req.sessionID].send(...)
but this would be great if wss.clients
could do that out of the box.

I think it's better to not add an id generator in this lib as there are multiple ways to generate ids and they depend on the application.
Closing, feel free to continue discussing on the closed thread.

Is there have a solution? Who can give me a URL to lean about this question..
