A custom 'shake' event JavaScript plugin for mobile web browsers using device accelerometer.

• Download: zip
• NPM: npm install shake.js
• Bower: bower install shake.js
• Git: git clone https://github.com/alexgibson/shake.js

Your web browser must support the devicemotion event for this plugin to work. Shake.js uses built-in feature detection to determine if it can run in your web browser. It will terminate silently on non-supporting browsers.

For CommonJS using NPM:

var Shake = require('shake.js');

For AMD module:

define(['./shake'], function(Shake) {
    // ...
});

In the browser:

<script src="shake.js"></script>

Next, create a new Shake instance:

var myShakeEvent = new Shake({
    threshold: 15, // optional shake strength threshold
    timeout: 1000 // optional, determines the frequency of event generation
});

Start listening to device motion:

myShakeEvent.start();

Register a shake event listener on window with your callback, you can get the shake strength in the callback function by accessing e.detail.strength property.

window.addEventListener('shake', shakeEventDidOccur, false);

//function to call when shake occurs
function shakeEventDidOccur (e) {

    //put your own code here etc.
    alert('Shake, the strength: ' + e.detail.strength);
}

You can stop listening for shake events like so:

window.removeEventListener('shake', shakeEventDidOccur, false);

To stop listening to device motion, you can call:

myShakeEvent.stop();
