You have to set the Environment and then you can configure your app like:

(This is a mongoose db and express, but you can find similar configurations.)

Simply set up three environment configurations

app.configure('development', function () {
  mongoose.connect(devConfig.db.path, function onMongooseError(err) {
  });
});

app.configure('production', function () {
  mongoose.connect(proConfig.db.path, function onMongooseError(err) {
  });
});

a configuration example (config.js) : 

var config = {};

// Database (MongoDB) configurations
config.db = {
path : 'mongodb://localhost/sampleDatabase'
};

module.exports = config;

I require this file in my app.js by var config = require('config')

You could do the Environment detection in the config file as well.
