import {Sortable} from '@shopify/draggable';

const announcements = {
  'drag:start': 'Draggable element picked up',
  'drag:stop': 'Draggable element dropped',
  'sortable:stopped': 'Draggable elements swapped',
}

const sortable = new Sortable(document.querySelectorAll('ul'), {
  draggable: 'li',
  announcements,
});

import {Sortable} from '@shopify/draggable';

const announcements = {
  'drag:start': (dragEvent) => {
    return `Picked up ${dragEvent.source.getAttribute('data-name')}`;
  },

  'drag:stop': (dragEvent) => {
    return `Dropped ${dragEvent.source.getAttribute('data-name')}`
  },

  'sortable:sorted': (sortableEvent) => {
    return `Sorted ${sortableEvent.dragEvent.source.getAttribute('data-name')} with ${sortableEvent.dragEvent.over.getAttribute('data-name')}`;
  },
}

const sortable = new Sortable(document.querySelectorAll('ul'), {
  draggable: 'li',
  announcements,
});
