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).

Documentation

UAParser([user-agent][,extensions])

typeof user-agent "string".

typeof extensions "array".

In The Browser environment you dont need to pass the user-agent string to the function, you can just call the funtion and it should automatically get the string from the window.navigator.userAgent, but that is not the case in nodejs. The user-agent string must be passed in nodejs for the function to work. Usually you can find the user agent in: request.headers["user-agent"].

Constructor

When you call UAParser with the new keyword UAParser will return a new instance with an empty result object, you have to call one of the available methods to get the information from the user-agent string. Like so:

new UAParser([uastring][,extensions])

let parser = new UAParser("user-agent"); // you need to pass the user-agent for nodejs
console.log(parser); // {}
let parserResults = parser.getResult();
console.log(parserResults);
/** {
  "ua": "",
  "browser": {},
  "engine": {},
  "os": {},
  "device": {},
  "cpu": {}
} */

When you call UAParser without the new keyword, it will automatically call getResult() function and return the parsed results.

UAParser([uastring][,extensions])
- returns result object { ua: '', browser: {}, cpu: {}, device: {}, engine: {}, os: {} }

Methods

Methods table

The methods are self explanatory, here's a small overview on all the available methods:

getResult() - returns all function object calls, user-agent string, browser info, cpu, device, engine, os: { ua: '', browser: {}, cpu: {}, device: {}, engine: {}, os: {} }.
getBrowser() - returns the browser name and version.
getDevice() - returns the device model, type, vendor.
getEngine() - returns the current browser engine name and version.
getOS() - returns the running operating system name and version.
getCPU() - returns CPU architectural design name.
getUA() - returns the user-agent string.
setUA(user-agent) - set a custom user-agent to be parsed.

getResult()
- returns { ua: '', browser: {}, cpu: {}, device: {}, engine: {}, os: {} }
getBrowser()
- returns { name: '', version: '' }

Using node.js

Note: Device information is not available in the NodeJS environment.

$ 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

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 <body> tag
// <body class="ua-browser-safari ua-devicetype-tablet">
$('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"}
