Fire cross-browser-convenient touch events

Tested with

DEMO

Supported Events
e.g. el.addEventListener('drag-move', e => console.log(e));

• tap / double-tap / triple-tap
• hold / tap-and-hold / double-tap-and-hold
• drag-start / drag-move / drag-end
• drag-enter / drag-leave / drop
• swipe-left / swipe-right / swipe-up / swipe-down
• pan-start / pan-move / pan-end
• resize-start / resize-move / resize-end

Overview

• This library is very focused on simplicity and design
• All events works for desktop browsers, of course, as well as mobile browsers.
• For simplicity, it does not deal with multi-touch events. e.g. two finger zoom, two finger swipe, etc. The reason is that each mobile browser has its own way of dealing with multi-touch events and this library does not make another hacks on the top of the default behaviour, which makes less maintainable and more complicated.
• It fires a Javascript event without using any callbacks, so that you can add event listener like a vanilla Javascript. This is unlike other touch library, which you have to learn their own way to use their own callbacks. myEl.addEventListener('drag-move', functione(e) {console.log(e)})

Usage

Include script tag into your html

  <div class="draggable">Drag This</div>
  <script src="https://unpkg.com/touch-ui/dist/touch-ui.min.js"></script>
  <script>
    TouchUI.draggable('.draggable', {axis: 'xy'});
  </script>

Install

1. install touch-ui node module

   $ npm install touch-ui --save-dev

2. Import TouchUI and use

   import TouchUI from './touch-ui';
   TouchUI.draggable(dragEls[0], {axis: 'xy'});

Examples

Tap and hold example

let tapHoldEl = document.querySelector('#tap-hold');
tapHoldEl.addEventListener('double-tap', e => console.log(e.eventName));

Drag example

let draggable = document.querySelector('.draggable');
TouchUI.draggable(draggable, {axis: 'xy'});

draggable.addEventListener('drag-start', e => console.log(e) );
draggable.addEventListener('drag-move', e => console.log(e) );
draggable.addEventListener('drag-end', e => console.log(e) );

Drag/Drop example

let draggable = document.querySelector('.draggable');
let dropzone  = document.querySelector('.dropzone');
TouchUI.draggable(draggable);
TouchUI.droppable(dropzone);

dropzone.addEventListener('drag-enter', e => console.log(e) );
dropzone.addEventListener('drag-leave', e => console.log(e) );
dropzone.addEventListener('drop',       e => e.target.appendChild(e.dragEl) );

Swipe example

let swipable = document.querySelectorAll('.swipable');
TouchUI.swipable(swipable);

el.addEventListener('swipe-right', e => console.log(e));

Pan example

let panTestEl = document.querySelector('#pan-test');
TouchUI.pannable(panTestEl);

panTestEl.addEventListener('pan-start', e => console.log(e) );
panTestEl.addEventListener('pan-move', e => console.log(e) );

Resize example

let resizableEl = document.querySelector('.resizable');
let resize = TouchUI.resizable(resizableEl, {positions: 'right'});
let startWidth, startHeight;

resizableEl.addEventListener('resize-start', e => console.log(e) );
resizableEl.addEventListener('resize-move', e => console.log(e) );
resizableEl.addEventListener('resize-end', e => console.log(e) );
