node-barefoot/lib/server/view-mixin.js

Barefoot makes code sharing between browser and server reality. Write your application once and run it on both ends of the wire.

/** Mixin: Barefoot.View.Server
 * Enhances the <Barefoot.View> class with server specific code fragments.
 * "Enhancing" is quite exaggerate: Actually it ensures that a few Backbone
 * methods are replaced with an empty implementation since barefoot do not want
 * them to query any DOM elements when rendering a view on the server. Following
 * methods are overridden:
 *
 * * setElement(element)
 * * delegateEvents()
 * * undelegateEvents()
 * * close(), actually not Backbone, but need an empty method body too
 *
 * See also:
 * * <Barefoot.View>
