I'll give it shot to build a super simple one with just vanilla JS without helper libraries like Lit or Stencil. I think I'd take the same approach as I would with React, and I think the biggest difference would be where the fetch gets executed. In React you'd expose a prop like "submitHandler", but here I would emit an event from the component (after whatever debounce amount) and expect the caller to attach an event listener to my custom event to perform the fetch.
The Stackblitz example is quite good too.
