Lightweight JavaScript-based User-Agent string parser. Supports browser & node.js environment. Also available as jQuery/Zepto plugin, Component/Bower/Meteor package, & RequireJS/AMD module
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.

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
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"}
