I can't get Angular (2+, not AngularJS) to play nice with my extended custom element, which is defined like so:
class FancyButton extends HTMLButtonElement
connectedCallback()
this.innerText = `I'm a fancy-button!`;
this.style.backgroundColor = 'tomato';
customElements.define("fancy-button", FancyButton,
extends: "button"
);
And used like so:
<button is="fancy-button">Fancy button here</button>
The definition is fully compliant to web standards according to this Google Developer resource:
https://developers.google.com/web/fundamentals/web-components/customelements#extend
It's working fine in a vanilla web setup and in React, but Angular ignores it and shows a standard button, apparently ignoring the is="fancy-button" attribute.
Here is a stackblitz showing this in action.
One fancy-button is outside the Angular scope (index.html) and is working fine.
The other button is inside the Angular scope (app.component.html) and is NOT working.
Why oh why?

I wouldn't even go that way... we have directives to use just for cases like this :) stackblitz.com/edit/angular-lqz3xt?file=src/app/…

I see. I'm doing this to be framework agnostic and I think the "is="fancy-button" approach is very nice for that. Works perfectly in React without any React-specific code.

I'm not using the <script> tag in a template. It's in the index.html file. However, I get your point and thanks for your reply. This question is about the same issue if you're interested: stackoverflow.com/questions/53604958/…
