Knockout dump binding handler.

DumpBinding.js

ko.bindingHandlers.dump = {
  init: function(element, valueAccessor, allBindingsAccessor, viewModel, bindingContext){
    var context = valueAccessor();
    var allBindings = allBindingsAccessor)();
    var pre = document.createElement('pre');
    
    element.appendChild(pre);
    
    var dumpJSON = ko.computed({
      read: function(){
        return ko.toJSON(context, null, 2);
      },
      disposeWhenNodeIsRemoved: element
    });
    
    // Lets you apply bindings programatically instead of declaritively
    ko.applyBindingsToNode(pre, {text: dumpJSON});    
  }
}
