Features

Extract detailed type of web browser, layout engine, operating system, cpu architecture, and device type/model purely from user-agent string with relatively lightweight footprint (~11KB minified / ~4KB gzipped). Written in vanilla js, which means it doesn't depends on any other library.

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 requirejs

require(['ua-parser'], function(UAParser) {
    var parser = new UAParser();
    console.log(parser.getResult());
});

Using component

$ component install faisalman/ua-parser-js

Using bower

$ bower install ua-parser-js

Using meteor

$ meteor add faisalman:ua-parser-js

Using jQuery/Zepto ($.ua)

Although written in vanilla js (which means it doesn't depends on jQuery), this library will automatically detect if jQuery/Zepto 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

Extending regex patterns

UAParser(uastring[, extensions])

Pass your own regexes to extend the limited matching rules.

// Example:
var uaString = 'ownbrowser/1.3';
var ownBrowser = [[/(ownbrowser)\/([\w\.]+)/i], [UAParser.BROWSER.NAME, UAParser.BROWSER.VERSION]];
var parser = new UAParser(uaString, {browser: ownBrowser});
console.log(parser.getBrowser());   // {name: "ownbrowser", version: "1.3"}
