I'm starting on node JS and I'm facing a problem with IO lib, here error:

You have to pass io on your way:
exports.index = function (io) {return function (rick, ridge) {res.render ('index'); Io.sockets.on ('connection', function (socket) {socket.emit ('message', 'welcome')}}}} and then as a function Call app.get :
requires app.get ('/', ('./bin'). Index (io)); I recommend the declaration of part ('. /' '>) with the other variables of your code. This code reuse and improved readability ( Which is relative to each person.
var / * other variables * /, lib = is required ('. / Lib'); then you can just do the app
Just get an idea. (/ ', Lib.index (io)).
