Important!
This repository is just a "copy" of the original agnostic-draggable with important bug fixes which have not yet been merged into the original. As a consequence, this repository may become obsolete as soon as the original package has been fixed.
The resulating package has been registered as NPM package "agnostic-draggable-bug-fixed"
(Original description follows)
Most of UI developers that worked with web apps from 2008 to 2014 certainly used or at least searched for a library implementing Drag & Drop support. From all the libraries that were available within that period, jQuery UI was certainly one of the best choices.
Years later, most of the web applications are tied to frameworks or rendering libraries like Angular, Vue and React and keeping jQuery and jQuery UI as a dependency to these projects can be a headache. In fact, moving away from jQuery is something that many development teams have experienced after these frameworks came into the scene.
However, finding a good replacement for what jQuery UI used to offer in terms of drag/drop capabilities is not easy. If you are looking for a solution that is tied to your framework/library of choice, there are plenty of options for you. But if you are looking for a VanillaJS based and agnostic implementation of drag & drop, you can find yourself browsing for a couple of hours finding just a few consistent options.
Shopify/Draggable is a nice alternative, although it has some crucial behaviour changes compared with what jQuery UI used to offer. SortableJS offers something similar to what the jQuery UI`s Sortable widget offers. By looking at the examples, it seems to be even possible to mimic the behavior of the "connectToSortable" option of jQuery UI's Draggable widget, that allows an item to be dragged onto a list that has sort capabilities. Native Drag & Drop implementation from the browser? Forget it until it can support dragging an element using a cloned helper node. Furthermore, the API offered by the native implementation really sucks.
The solution? Translate the implementation of the Draggable, Droppable and Sortable widgets from jQuery UI into an agnostic, VanillaJS and ES6+ based library. Most of the options and features found in the original implementation by jQuery UI's team are here. The ones that were not translated/rewritten were just not part of the subset of features considered to be the most important ones. This doesn't mean that contributors cannot help finishing the task of bringing them in.
Install
Using NPM, type in the following command to install agnostic-draggable:
npm i agnostic-draggable --saveUsage and Documentation
Draggable
Enables dragging functionality on any DOM element. Move the Draggable element by clicking on it and dragging it anywhere within the viewport.
Elements modified or created will use the same CSS classes inherited from jQuery UI's implementation:
- ui-draggable: the element being dragged
- ui-draggable-handle: the handle of the draggable element. By default, each draggable is also a handle
- ui-draggable-helper: the dragging helper

<div id="drag1">Drag Me</div>
<div id="drop1">Drop Here</div>import { Draggable, Droppable } from 'agnostic-draggable';

The fit option requires the dragging element to overlap the droppable area entirely.
The intersect option requires the dragging element to overlap the droppable area at 50% in both directions.
The pointer requires the mouse pointer to overlap the droppable area.
The touch requires the dragging element to overlap the droppable area in any amount or direction.

Sortable
Transforms elements that contains multiple child nodes in a way that these child nodes can be sorted by using the mouse.
Elements modified or created will use the same CSS classes inherited from jQuery UI's implementation:
- ui-sortable: the element containing the sortable elements
- ui-sortable-handle: the handle of each sortable item. By default, each sortable item is also a handle
- ui-sortable-helper: the element shown when dragging a sortable item
- ui-sortable-placeholder: the element used to show the future position of the item being dragged
In order to use this component to sort table rows, the element passed should be the
tbody, not thetable.
