How is this supposed to work? With reactJS I know I can server render a component or template and I’ll say JSX makes a pretty good tempting language. With web components as far as I understand there is no good templating language built in anyways (so you have to bring your own) I’m not aware of a standard mechanism in which I can take some chunk of JS for a component associated with a tag and have it render out HTML that does not require JS to run.
