Wrapping things in objects doesn't seem to help me.

I'd still end up with this, thanks to callbacks.

    app.get('/documents', function(req, res) {
      Document.find().all(function(documents) {
        // 'documents' will contain all of the documents returned by the query
        res.send(documents.map(function(d) {
          // Return a useful representation of the object that res.send() can send as JSON
          return d.__doc;
        }));
      });
    });
Seems to me that what's missing is something that lets me write it in a more simple way. What I have here looks like an absolute nightmare of coupling. So if you have some suggestions you could point me to that show a little more detail, I'd be really grateful.



I would create a DocumentRequest object that takes your req and res, then break apart your callbacks to separate functions on the DocumentRequest prototype. Then you would simply consume it with:

  app.get('/documents', new DocumentRequest);


Thanks for this. Been thinking about this. Could you recommend a book on patterns like these?
