UAParser.js
JavaScript library to detect Browser, Engine, OS, CPU, and Device type/model from User-Agent data with relatively small footprint (~17KB minified, ~6KB gzipped) that can be used either in browser (client-side) or node.js (server-side).

Usage

Using HTML








Using node.js
$ npm install ua-parser-js
var http = require(‘http’);
var parser = require(‘ua-parser-js’);

http.createServer(function (req, res) {
// get user-agent header
var ua = parser(req.headers[‘user-agent’]);
// write the result as response
res.end(JSON.stringify(ua, null, ‘ ‘));
})
.listen(1337, ‘127.0.0.1’);

console.log(‘Server running at http://127.0.0.1:1337/’);

Using TypeScript
$ npm install –save @types/ua-parser-js
# Download TS type definition from DefinitelyTyped repository:
# https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/ua-parser-js

Using jQuery/Zepto ($.ua)
Although written in vanilla js, this library will automatically detect if jQuery/Zepto is present and create $.ua object (with values based on its User-Agent) along with window.UAParser constructor. To get/set user-agent you can use: $.ua.get() / $.ua.set(uastring).
// Say we are in a 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’:

// Get the details
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”

// Now lets try to reset to another 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

// Add class to tag
//
$(‘body’).addClass(‘ua-browser-‘ + $.ua.browser.name + ‘ ua-devicetype-‘ + $.ua.device.type);

Using Extension

UAParser([uastring,] extensions)

// Example:
var myOwnListOfBrowsers = [
[/(mybrowser)/([w.]+)/i], [UAParser.BROWSER.NAME, UAParser.BROWSER.VERSION]
];
var myParser = new UAParser({ browser: myOwnListOfBrowsers });
var myUA = ‘Mozilla/5.0 MyBrowser/1.3’;
console.log(myParser.setUA(myUA).getBrowser()); // {name: “MyBrowser”, version: “1.3”}
