@amplitude/ua-parser-js

UAParser.js
A JavaScript-based User-Agent string parser. Can be used either in browser (client-side) or in node.js (server-side) environment. Also available as jQuery/Zepto plugin, Bower/Meteor package, & RequireJS/AMD module. This library aims to identify detailed type of web browser, layout engine, operating system, cpu architecture, and device type/model, entirely from user-agent string with a relatively small footprint (~17KB when minified / ~6KB gzipped). Written in vanilla JavaScript, which means it doesn’t require any other library and can be used independently. However, it’s not recommended to use this library as browser detection since the result may not be more accurate than using feature detection.

Example
 
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
requirejs.config({    baseUrl : ‘js/lib’, // path to your script directory    paths   : {        ‘ua-parser-js’ : ‘ua-parser.min’    }}); requirejs([‘ua-parser-js’], function(UAParser) {    var parser = new UAParser();    console.log(parser.getResult());});
Using CDN

Using bower
$ bower install ua-parser-js
Using meteor
$ meteor add faisalman:ua-parser-js
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 (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() / $.ua.set(uastring).
// In browser with default user-agent: ‘Mozilla/5.0 (Linux; U; Android 2.3.4; en-us; Sprint APA7373KT Build/GRJ22) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0’: // Do some testsconsole.log($.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 againconsole.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);
Extending regex patterns

UAParser([uastring,] extensions)

Pass your own regexes to extend the limited matching rules.
// Example:var myOwnRegex = [[/(myownbrowser)/([w.]+)/i], [UAParser.BROWSER.NAME, UAParser.BROWSER.VERSION]];var myParser = new UAParser({ browser: myOwnRegex });var uaString = ‘Mozilla/5.0 MyOwnBrowser/1.3’;console.log(myParser.setUA(uaString).getBrowser());   // {name: “MyOwnBrowser”, version: “1.3”}
