NodeJS and PhoneGap

Phonegap is a client-side solution only with JavaScript/CSS/HTML running on the browser-app of the phone. The JavaScript Phonegap API talks to the native phone interface and browser interface which gives you options to work natively and as a normal web page would with enhanced permissions. Node.js would only serve you as a data connection for JSON or whatever else you would need to pull/push with a network call.
