Usage

{{!-- this.list = [{ name: 'item one' }, { name: 'item two' },..]  --}}
<SortableJs
  @items={{this.list}}
  @options={{hash animation=150 ghostClass="ghost-class" group="shared-list"}}
  @onStart={{this.onStart}}
  @onEnd={{this.onEnd}}
  as |list|
>
  {{#each list as |item|}}
    <div class="list-group-item bg-yellow">{{item.value.name}}</div>
  {{/each}}
</SortableJs>

How it works

SortableJs works by manipulating the DOM directly this is NOT compatible with the Glimmer VM. To mitigate this we need tu use SortableJs as a middle man and use the events it emits to update state and prevent the DOM manipulation the library does.

This is accomplished by maintaining an internal list. This list is a copy of the array supplied via @items. The events onStart, onEnd, onUpdate, onAdd, onRemove are intercepted to prevent DOM manipulation and maintaining the internal list.

You HAVE to provide an object. As the addon uses a WeakMap to cache the items supplied. When SortableJs emits we update the list and the cache to make changes that will update the DOM. The addon will yield an array of objects. Each object contains the key value, which is the original object supplied via @items.

I you have ideas on how to approach this better. Please open an issue 😄

Caveats

• Not all SortableJS plugins work... yet.
• While you could bypass @items I highly discourage since the library manipulates the DOM directly.

Options

The addon supports all the options that sortable accepts, see: https://github.com/SortableJS/Sortable#options

SortablejsEvent - A CustomEvent provided by SortableJS

SortablejsMoveEvent - A CustomEvent provided by SortableJS

cancelDnD - A callback provided by the ember addon to basically undo you last drag and drop or sort;

{{yield}} - An array of objects with the key value where its value is the object supplied. { value: <Object> }

Migrating from 1.x

• onSetData is no longer suported. Rename argument to setData.
• <SortableJs> no longer expects a wrapped list. Instead the addon itself will act as the sortable list container.

v1

<SortableJs
  @options={{hash animation=150 ghostClass="ghost-class" group="shared-list"}}

    <li class="list-group-item">Item 1</li>
    <li class="list-group-item">Item 2</li>
    <li class="list-group-item">Item 3</li>
    <li class="list-group-item">Item 4</li>
    <li class="list-group-item">Item 5</li>
  </ul>
</SortableJs>

v2

{{!-- this.list = [{ name: 'item one' }, { name: 'item two' },..]  --}}
<SortableJs
