## Overview

This in the HTML import version of the WebComponent version of this component. See here for the standalone version. This file is included via script tag in hy-drawer.html and shouldn’t be used via ES import.


import { customElementMixin, CustomElement } from "hy-component/src/custom-element";

import { drawerMixin } from "../mixin";

const define = () => {
customElements.define(
"hy-drawer",
class extends customElementMixin(drawerMixin(CustomElement)) {


The CustomElements spec demands that we provide a list of attributes (i.e. our options).

      static get observedAttributes() {
return this.getObservedAttributes();
}
}
);
};


Make sure the polyfills are ready (if they are being used).
