- Don't shim CSS Custom Properties in IE11
<!-- Place this in the <head>, before the Web Component polyfills are loaded -->
<script>
if (!window.Promise) {
window.ShadyCSS = { nativeCss: true };
}
</script>You have two options for polyfills library:

$ npm i @open-wc/polyfills-loader- Load it
import loadPolyfills from '@open-wc/polyfills-loader';
loadPolyfills().then(() => import('./my-app.js'));- Installation
