Visual Designer to Generate Javascript Code from class diagram or etc

I am looking for desktop executable or Browser based(if one exists) application that could generate javascript code for me from a visual designer. Something like Ext Designer that Sencha developed for their library. If there is a tool that could generate javascript code from Class Diagrams i would also love to see them. Visual Does开发者_如何学编程 it exactly but for Server Side code "C#" and others. I am looking for the same functionality.

have you ever heard of Morfik?
