Installation
$ component install component/user-agent-parser
Example
var parse = require('user-agent-parser');
parse('user agent string')
// => Object
Features
Extract detailed type of web browser, layout engine, operating system, and device purely from user-agent string with relatively lightweight footprint (~7KB minified / ~3KB gzipped). Written in vanilla js, which means it doesn't depends on any other library.

Example
<!doctype html>
<html>
<head>
<script type="text/javascript" src="ua-parser.min.js"></script>
<script type="text/javascript">
var parser = new UAParser();
// by default it takes ua string from current browser's window.navigator.userAgent
console.log(parser.getResult());
/*
/// this will print an object structured like this:
{
browser: {
name: "",
version: "",
major: ""
},
engine: {
name: "",
version: ""
},
os: {
name: "",
version: ""
},
device: {
model: "",
type: "",
vendor: ""
},
cpu: {
architecture: ""
}
}
*/
// let's test a custom user-agent string as an example
var uastring = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.2 (KHTML, like Gecko) Ubuntu/11.10 Chromium/15.0.874.106 Chrome/15.0.874.106 Safari/535.2";
parser.setUA(uastring);
var result = parser.getResult();
// this will also produce the same result (without instantiation):
// var result = UAParser(uastring);
console.log(result.browser); // {name: "Chromium", major: "15", version: "15.0.874.106"}
console.log(result.device); // {model: undefined, type: undefined, vendor: undefined}
console.log(result.os); // {name: "Ubuntu", version: "11.10"}
console.log(result.os.version); // "11.10"
console.log(result.engine.name); // "WebKit"
console.log(result.cpu.architecture); // "amd64"
// do some other tests
var uastring2 = "Mozilla/5.0 (compatible; Konqueror/4.1; OpenBSD) KHTML/4.1.4 (like Gecko)";
console.log(parser.setUA(uastring2).getBrowser().name); // "Konqueror"
console.log(parser.getOS()); // {name: "OpenBSD", version: undefined}
console.log(parser.getEngine()); // {name: "KHTML", version: "4.1.4"}
var uastring3 = 'Mozilla/5.0 (PlayBook; U; RIM Tablet OS 1.0.0; en-US) AppleWebKit/534.11 (KHTML, like Gecko) Version/7.1.0.7 Safari/534.11';
console.log(parser.setUA(uastring3).getDevice().model); // "PlayBook"
console.log(parser.getOS()) // {name: "RIM Tablet OS", version: "1.0.0"}
console.log(parser.getBrowser().name); // "Safari"

Using node.js
$ npm install ua-parser-js
var UAParser = require('ua-parser-js');
var parser = new UAParser();
var ua = request.headers['user-agent']; // user-agent header from an HTTP request
console.log(parser.setUA(ua).getResult());
Using requirejs
require(['ua-parser'], function(UAParser) {
var parser = new UAParser();
console.log(parser.getResult());
});
Using component
$ component install faisalman/ua-parser-js
var UAParser = require('ua-parser-js');
var parser = new UAParser();
console.log(parser.getResult());
Using bower
$ bower install ua-parser-js
Using jQuery.ua
Although written in vanilla js (which means it doesn't depends on jQuery), this library will automatically detect if jQuery is present and create $.ua object based on browser's user-agent (although in case you need, window.UAParser constructor is still present). To get/set user-agent you can use: $.ua.get() / $.ua.set(uastring).
// In browser with default user-agent: 'Mozilla/5.0 (Linux; U; Android 2.3.4; en-us; Sprint APA7373KT Build/GRJ22) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0':
// Do some tests
console.log($.ua.device); // {vendor: "HTC", model: "Evo Shift 4G", type: "mobile"}
console.log($.ua.os); // {name: "Android", version: "2.3.4"}
console.log($.ua.os.name); // "Android"
console.log($.ua.get()); // "Mozilla/5.0 (Linux; U; Android 2.3.4; en-us; Sprint APA7373KT Build/GRJ22) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0"
// reset to custom user-agent
$.ua.set('Mozilla/5.0 (Linux; U; Android 3.0.1; en-us; Xoom Build/HWI69) AppleWebKit/534.13 (KHTML, like Gecko) Version/4.0 Safari/534.13');
// Test again
console.log($.ua.browser.name); // "Safari"
console.log($.ua.engine.name); // "Webkit"
console.log($.ua.device); // {vendor: "Motorola", model: "Xoom", type: "tablet"}
console.log(parseInt($.ua.browser.version.split('.')[0], 10)); // 4
