How to extend shim/mixin?

Dear Ionic-Community,

I want ::theme support for my Stencil components using GitHub - PolymerLabs/part-theme: Experimental proof of concept shim for ::part/::theme css.. Polymer’s demo gives an usage example by extending like this:

class PartThemeElement extends PartThemeMixin(HTMLElement) {} [1]

But Stencil errors: Classes decorated with @Component can not extend from a base class.

Is there any other way I can make use of the mixin?

Thanks in advance,

Hi Jonas,

At this time, there is no way to make use of this Mixin in Stencil. However, there is an open PR from a community member that the team is internally considering. Please consider giving that an upvote if it meets your needs!
