node.js / mongodb file structure

I'm trying to set up this simnple NodeJS/mongodb app and I have my files structured like this:

server.js
    |
    +-routes/menu.js
    +-routes/cases.js

In my server.js I declare my mongodb vars like this:

var express = require('express'),
    mongo = require('mongodb'),
    Server = mongo.Server,
    MongoClient = mongo.MongoClient,
    Db = mongo.Db,
    http = require('http'),
    app = express(),
    httpServer = http.createServer(app),
    bodyParser = require('body-parser'),
    server = new Server('host.mongohq.com', 10066, {auto_reconnect : true}),
    db = new Db('myDb', server);

db.open(function(err, client) {
    client.authenticate('myUser', 'myPassword', function(err, success) {
        console.log('Authenticated');
    });
});
var cases = require('./routes/cases'),
    menu = require('./routes/menu');

But then when I try to reference my db var in eg menu.js like this:

db.collection(myCollection, function(err, collection) {});

I get an error that db is not defined.

Obviously I can move all the mongodb declarations down to both my menu.js and cases.js file but that's just very elegant. So how do I create one mongodb instance var and refer to it from my included files?

Thanks in advance...

You need to require server.js in your menu.js file.

Your db object isn't global. If you want it to be, declare it without var.
