TODO: Add unit tests

installation

npm i --save touchy

usage

// usually this is enough to generate the events
// this can be done in a module that can be required
// at the beginning of your app to generate the events
var touchy = require('touchy');
touchy.enableOn(document);

Events

This library will generate the following events:

  • tap
  • tap:hold
  • swipe
  • swipe:up
  • swipe:down
  • swipe:left
  • swipe:right

tap

The tap event is generated when:

  • a touchstart/mousedown event is followed by a touchend/mouseup
  • the end target is the same as the start target
  • the user hasn't move the finger between the starting event and the end event for more than options.minTapDisplacementTolerance (default: 10px)
  • the time between touchstart/mousedown and touchend/mouseup is less than opts.tapHoldMinThreshold (default: 500ms)

Example

// usually this is enough to generate the events
var touchy = require('touchy');
touchy.enableOn(document);
 
var ele = document.querySelector('#selector');
ele.on('tap', function (e) {
  console.log('tap!');
});

tap:hold

The tap:hold event is generated when:

  • a touchstart/mousedown event is followed by a touchend/mouseup
  • the end target is the same as the start target
  • the user hasn't move the finger between the starting event and the end event for more than options.minTapDisplacementTolerance (default: 10px)
  • the user has not released the finger for more than opts.tapHoldMinThreshold (default: 500ms)

Example

// usually this is enough to generate the events
var touchy = require('touchy');
touchy.enableOn(document);
 
var ele = document.querySelector('#selector');
ele.on('tap:hold', function (e) {
  console.log('tap:hold!');
});

swipe, swipe:left, swipe:right, swipe:up and swipe:down

The swipe event is generated when

  • a touchstart/mousedown event is followed by touchmove/mousemove and then by a touchend/mouseup
  • the user has moved the finger between the starting event and the end event for more than options.minTapDisplacementTolerance (default: 10px)
  • a tap:hold event has not being generated

Example

// usually this is enough to generate the events
var touchy = require('touchy');
touchy.enableOn(document);
 
var ele = document.querySelector('#selector');
ele.on('swipe', function (e) {
  console.log('swipe', e.detail.direction); // direction: down, up, left, right
});

Custom events are also generated with the direction of the swipe: swipe:left, swipe:right, swipe:up and swipe:down

// usually this is enough to generate the events
var touchy = require('touchy');
touchy.enableOn(document);
 
var ele = document.querySelector('#selector');
ele.on('swipe:left', function (e) {
  console.log('swipe:left');
});
