>These are web components and work fine within React already I tried with a simple CodeSandbox and they are not working for me. ( Unless I'm doing something wrong? ) https://codesandbox.io/s/pp4q7kw9q7

There's something weird going on in Chrome. This link works in Firefox though with the webcomponents polyfill https://codesandbox.io/s/jn85y61kx9

All working with react now. There was an issue wired-elements code: Here's a react demo: https://stackblitz.com/edit/wired-elements-react?file=index....

I believe it's a shadow dom issue. Firefox doesnt support Shadow DOM yet so a 'shady dom' is used by the polyfill

This seems to be because you are accessing the DOM of the element from the constructor which is a no no. Here's a simple repro:

stuff like this is why i have trust issues with people who try to push webcomponents on me. I'm either not smart enough to understand why i dont get it, or its just not ready yet.

i know and it was more just an exercise for myself. polymer and react interop still isnt very nice as far as i can tell. calm down :)

Those elements don't use polymer, they use lit-element - it is from polymer team and uses one polymer mixin, but its not polymer base element.

You can just import these into JS modules and use them in JSX. Interop is fine for attributes.

I'm perfectly calm dude.

What could we do better?

i don't know. wanna try putting up a codesandbox to use wired-elements in a react app? would love to learn. sorry i dont know your affiliation with the polymer project or react-polymer. it just didnt seem usable when i looked at it
