svelte-drag-drop-touch

HTML5 Drag-and-Drop support for mobile devices (not only for Svelte)

NPM users: please consider the Github README for the latest description of this package (as updating the docs would otherwise always require a new NPM package version)

Installation

npm install svelte-drag-drop-touch

Usage

<script>
  import DragDropTouch from 'svelte-drag-drop-touch'
</script>

from then on, HTML5 Drag-and-Drop may also be used on mobile devices.

Example

Several examples are available on the Svelte REPL - feel free to play with them! The most basic one is

• svelte-drag-drop-touch

Additional, more detailled examples may be found below.

Background Information

Bernardo Castilho has written a nice (and lightweight) Drag-and-Drop polyfill which brings HTML5 Drag-and-Drop capabilities to mobile devices. Unfortunately, the NPM package for that polyfill is outdated and does not seem to be updated.

svelte-drag-drop-touch just brings a TypeScript definition file and a trivial wrapper around the original code and bundles these with the latest version of DragDropTouch.js into an NPM package that may easily be imported into (not only) a Svelte application.

All the heavy lifting is done by DragDropTouch.js, thus, all credits go to Bernardo Castilho!

Additional Examples

• Drop- and No-Drop-Zones - look where the events are sent to
• plain Dragging - could be used to combine plain dragging with drag-and-drop
• Flicking - illustrates a simple approach to "flicking"
