Tap Event
Build Status
Make your touchstart event listeners into a tap event listener!
What is "correct" behavior? The tap event:
  • shouldn't be triggered until the user removes his/her finger from the surface of the screen.
  • shouldn't be triggered when the user moves his/her finger at all (ie it should not interfere with drag events).
  • shouldn't be triggered if there's ever more than a single finger on the surface at all.
  • should never trigger the click event.

Preserve context and arguments in 1.1.0, works with delegate easily


npm install component-tap-event -S


var tap = require('tap-event')

var el = document.querySelector('#container')

// the event you want to handle
function changeLocation(e) {
  // e.preventDefault() is already called!
  location.href = this.href

// wrap the listener
var listener = tap(changeLocation)

// listen to `touchstart`
el.addEventListener('touchstart', listener)

// remove the listener
el.removeEventListener('touchstart', listener)

or, more succinctly:
document.querySelector('#container').addEventListener('touchstart', tap(function (e) {
  location.href = this.href

To set a custom timeout (default is 200ms), you have two options:
// set globally
tap.timeout = 300

// set per instance
tap(function (e) {

}, {
  timeout: 300
