node.js - exports.* functions: getting other variables -

i have following code:

//app.js var ioroutes = require('./controllers/socket'); sio.sockets.on('connection', ioroutes.connection);  //socket.js exports.connection = function(socket){   console.log('i have ' + socket); }; 

now, app.js can access sio object, want use see how many clients have connected. how can pass sio object exported 'connection' function?

thanks in advance.

you need add parameter connection function:

//app.js var ioroutes = require('./controllers/socket'); sio.sockets.on('connection', function(socket) {   ioroutes.connection(socket, sio); });  //socket.js exports.connection = function(socket, sio){   console.log('i have ' + socket); };
