It depends on how complex your front-end is. As you put more logic on the client-side, the chance of some of that code being useful on the server-side grows. For example, the Objective-J compiler and loader system ( http://github.com/280north/cappuccino/tree/master/Objective-J/ http://github.com/280north/cappuccino/tree/master/Objective-... ) runs with almost no modification both in the browser-- for on-the-fly compilation during development-- and from the command line-- for pre-compilation prior to deployment. (As an aside it runs on Narwhal, not Node.JS. But the point stands.)
