javascript - Getting the list of polymer published properties

Question

Is there a way of getting the list of all published properties defined in a polymer component? (e.g. get the available properties of component public API)

<polymer-element name="sample-component"
                 attributes="foo1 foo2" bar="10">
   /* ... */
</polymer-element>

<sample-component foo1="5"></sample-component>


document.querySellector('sample-component').attributes;
// returns bar and foo1 (which have a value assigned to them)
// but I want to get foo1 and foo2

Answer 1

It's best to use element.publish to get the list of published properties for an element. (In polymer 1.0 element.properties does the same).

element.getAttribute('attributes) won't include the publish properties that are setup in a publish block.
