Caffeine

Lightweight library for mobile web browsers to prevent phones from sleeping.

Installation

Copy the file ./lib/caffeine.js or the minified version to your web server and then link it in your HTML:

<script type="text/javascript" src="caffeine.min.js"></script>

Usage

At the bottom of your document after including caffeine.js, add the following:

<script>
  caffeine.start(); // keep phone awake

  caffeine.stop();  // allow phone to sleep
</script>

Or with browserify, your pre-build js file would look like:

var caffeine = require('caffeine');

caffeine.start(); // keep phone awake

caffeine.stop();  // allow phone to sleep

Supported Platforms

• iOS 7.1.2, Safari
