import { html } from 'lit-html';

import './demo-button';

export default {
  title: 'Components/Button',
};

//👇 We create a “template” of how args map to rendering
const Template = ({ primary, label }) =>
  html`<demo-button ?primary=${primary} .label=${label}></demo-button>`;

//👇 Each story then reuses that template
export const Primary = Template.bind({});
