node.js - Handle disconnect / logout events -

after connecting client subscribes specific room contains connected users:

io.socket.get('/connection/subscribe', function(data, jwr) {   io.socket.on('user_connected', function(user) { console.log('new bro connected'); }); }); 

at moment i'm storing user ids in memory. therefor use single variable,

var connectionids = [];  /*...*/ subscribe: function(req, res) {     if(typeof req.user !== 'undefined') {         sails.sockets.join(req.socket, 'users_online');          user.find(req.user.id).exec(function(err, user) {             if(connectionids.indexof(user[0].id) == -1) {                 connectionids.push(user[0].id);             }             sails.sockets.broadcast('users_online', 'user_connected', user);         });          return res.ok();     } }, 

everything works fine far, problem handling disconnect or logout events. after closing window, logging out or similar need unsubsribe users_online room.

already tried

io.socket.on('disconnect', function() { io.socket.post('/disconnect', function() { })); 

but sadly request never sent. how handle disconnect event properly?

may example helps you: http://socket.io/docs/#sending-and-receiving-events

disconnect fired inside of .on('connection'). can detect disconnecting on server-side , client-side of project.
