# [hammer.js][hammerjs-url] [![NPM Version][npm-image]][npm-url] [![NPM Downloads][downloads-image]][downloads-url] [![Build Status][travis-image]][travis-url]
> A JavaScript library for detecting touch gestures.
## Installation
### NPM
```sh
npm install --save hammerjs
```
**or**
### Yarn
```sh
yarn add hammerjs
```
**or**
### CDN
[https://cdnjs.com/libraries/hammer.js/](https://cdnjs.com/libraries/hammer.js/)
## Usage
hammer.js has a quick start option for gestures it already recognizes.
```js
// Get a reference to an element.
var square = document.querySelector('.square');
// Create an instance of Hammer with the reference.
var hammer = new Hammer(square);
// Subscribe to a quick start event: press, tap, or doubletap.
// For a full list of quick start events, read the documentation.
hammer.on('press', function(e) {
e.target.classList.toggle('expand');
console.log("You're pressing me!");
console.log(e);
});
```
If you want to recognize your own gestures, such as `tripletap`, then you'll have to use these steps:
```js
// Get a reference to an element.
var square = document.querySelector('.square');
// Create a manager to manage the element.
var manager = new Hammer.Manager(square);
// Create a recognizer.
var TripleTap = new Hammer.Tap({
event: 'tripletap',
taps: 3
});
// Add the recognizer to the manager.
manager.add(TripleTap);
// Subscribe to the event.
manager.on('tripletap', function(e) {
e.target.classList.toggle('expand');
console.log("You're triple tapping me!");
console.log(e);
});
```
