where to code business logic in nodejs with expressjs, mongoosejs and redis

Question

My business logic includes mongodb operations and redis operations on one request. I do not know where we should put logic code to. In Java project, we have DAO, service and controler objects. but in nodejs projects, I don't know where to put my code. shall I put logic code to routes/index.js?

app.post('/deal', function(req, res) {
    ... //TODO: here

});

or create a kind of service objects such as what we do in Java proejct?

Here's a question that might help: Mongoose-based app architecture

You should also look at the http://mean.io stack, as their templates will show you how to best structure your app, including where to store your logic.
