How to store client associated data in socket.io 1.0

Question

The docs say socket.io doesn\'t support .get .set now

Is it okay to store client associated data like

io.sockets.on(\'connection\', function (client) {
         


        

Answer 1

Yes, that's possible as long as there is no other builtin properties with same name.

io.sockets.on('connection', function (client) {
    client.on('data', function (somedata) {  
        // if not client['data']  you might need to have a check here like this
        client['data'] = somedata;
    });    
});

I'd suggest another way, but with ECMAScript 6 weak maps

var wm = new WeakMap();

io.sockets.on('connection', function (client) {
    client.on('data', function (somedata) {   
        wm.set(client, somedata);
        // if you want to get the data
        // wm.get(client);
    }); 
    client.on('disconnect', function() {
        wm.delete(client);
    });   
});
