FastClick is a simple, easy-to-use library for eliminating the 300ms delay between a physical tap and the firing of a

event on mobile browsers. The aim is to make your application feel less laggy and more responsive while avoiding any interference with your current logic.

FastClick is developed by FT Labs, part of the Financial Times.

Note: As of late 2015 most mobile browsers - notably Chrome and Safari - no longer have a 300ms touch delay, so fastclick offers no benefit on newer browsers, and risks introducing bugs into your application. Consider carefully whether you really need to use it.

Explication en français.


Why does the delay exist?

According to Google: browsers will wait approximately 300ms from the time that you tap the button to fire the click event. The reason for this is that the browser is waiting to see if you are actually performing a double tap.


The library has been deployed as part of the FT Web App and is tried and tested on the following mobile browsers:

  • Mobile Safari on iOS 3 and upwards
  • Chrome on iOS 5 and upwards
  • Chrome on Android (ICS)
  • Opera Mobile 11.5 and upwards
  • Android Browser since Android 2
  • PlayBook OS 1 and upwards

When it isn't needed

FastClick doesn't attach any listeners on desktop browsers.

Chrome 32+ on Android with

in the viewport meta tag doesn't have a 300ms delay, therefore listeners aren't attached.

Same goes for Chrome on Android (all versions) with

in the viewport meta tag. But be aware that
also disables pinch zooming, which may be an accessibility concern.

For IE11+, you can use

touch-action: manipulation;
to disable double-tap-to-zoom on certain elements (like links and buttons). For IE10 use
-ms-touch-action: manipulation


Include fastclick.js in your JavaScript bundle or add it to your HTML page like this:

The script must be loaded prior to instantiating FastClick on any element of the page.

To instantiate FastClick on the

, which is the recommended method of use:
if ('addEventListener' in document) {
    document.addEventListener('DOMContentLoaded', function() {
    }, false);

Or, if you're using jQuery:

$(function() {

If you're using Browserify or another CommonJS-style module system, the

function will be returned when you call
. As a result, the easiest way to use FastClick with these loaders is as follows:
var attachFastClick = require('fastclick');



to build a minified version of FastClick using the Closure Compiler REST API. The minified file is saved to
or you can download a pre-minified version.

Note: the pre-minified version is built using our build service which exposes the

object through
and will have the Browserify/CommonJS API (see above).
var attachFastClick = Origami.fastclick;


FastClick has AMD (Asynchronous Module Definition) support. This allows it to be lazy-loaded with an AMD loader, such as RequireJS. Note that when using the AMD style require, the full

object will be returned, not
var FastClick = require('fastclick');
FastClick.attach(document.body, options);

Package managers

You can install FastClick using Component, npm or Bower.

For Ruby, there's a third-party gem called fastclick-rails. For .NET there's a NuGet package.


Ignore certain elements with

Sometimes you need FastClick to ignore certain elements. You can do this easily by adding the

Ignored by FastClick

Use case 1: non-synthetic click required

Internally, FastClick uses

to fire a synthetic
event as soon as
is fired by the browser. It then suppresses the additional
event created by the browser after that. In some cases, the non-synthetic
event created by the browser is required, as described in the triggering focus example.

This is where the

class comes in. Add the class to any element that requires a non-synthetic click.

Use case 2: Twitter Bootstrap 2.2.2 dropdowns

Another example of when to use the

class is with dropdowns in Twitter Bootstrap 2.2.2. Bootstrap add its own
listener for dropdowns, so you want to tell FastClick to ignore those. If you don't, touch devices will automatically close the dropdown as soon as it is clicked, because both FastClick and Bootstrap execute the synthetic click, one opens the dropdown, the second closes it immediately after.


FastClick is designed to cope with many different browser oddities. Here are some examples to illustrate this:


There are no automated tests. The files in

are manual reduced test cases. We've had a think about how best to test these cases, but they tend to be very browser/device specific and sometimes subjective which means it's not so trivial to test.
