Installation and usage

In a browser:

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

Via npm:

npm install platform

In Node.js and RingoJS:

var platform = require('platform');

In Rhino:

load('platform.js');

In an AMD loader like RequireJS:

require({
  'paths': {
    'platform': 'path/to/platform'
  }
},
['platform'], function(platform) {
  console.log(platform.name);
});

Usage example:

// on IE10 x86 platform preview running in IE7 compatibility mode on Windows 7 64 bit edition
platform.name; // 'IE'
platform.version; // '10.0'
platform.layout; // 'Trident'
platform.os; // 'Windows Server 2008 R2 / 7 x64'
platform.description; // 'IE 10.0 x86 (platform preview; running in IE 7 mode) on Windows Server 2008 R2 / 7 x64'

// or on an iPad
platform.name; // 'Safari'
platform.version; // '5.1'

platform.manufacturer; // 'Apple'
platform.layout; // 'WebKit'
