One possible way to simplify hyperHTML components.

hyper-element.js

const borrowedState = require('flatstate').setState;

class HyperElement extends HTMLElement {
  constructor(...args) {
    super(...args);
    this.html = hyperHTML.bind(this);
  }

  render() {}

  setState(state) {
    borrowedState.call(this, state);
    this.render();
  }
}
