Trying to display data from mongodb database in node.js app

Question

server.get('/', function(req, res) {
    Counter.find({}, function(err, result) {
        if (!(err)) {
            res.render('index', {'lol' : result});
        }
    });
});

I'm trying to get my app to display the contents of the whole database and this is what I came up with. Counter is a mongoose model. The database contains some items inserted prior to the execution of the program and one item inserted in the app itself.

Something is really iffy conceptually to me (I'm new to node), I think render() is being executed before find() which is why I'm not getting a result, but I can't think of a solution. Any help or push in the right direction is greatly appreciated. :)

res.render will definitely execute after the find completes as you've correctly put it in the find callback. What's specifically not working? — JohnnyHK

The problem was with the db, not the code. Thanks for the help! :) — Igor Šćekić

What is your view code?

Your implementation is correct, you should try to do debug.

server.get('/', function(req, res) {
  Counter.find({}, function(err, result) {
    if (!(err)) {
        console.log('Debug: ' + JSON.stringify(result) );
        res.render('index', {lol : result});
    }
  });
});

The problem was with my db, I was trying to access a collection which contained no data. In hindsight, silly mistake. Thanks for the help. :)
