UAParser([user-agent:string][,extensions:object][,headers:object(since@2.0)]):IData
In browser environment you don’t need to pass the user-agent string to the function, as it should automatically get the string from the window.navigator.userAgent
. Whereas in nodejs environment, the user-agent string must be passed in order for the function to work (usually you can find the user-agent in: request.headers["user-agent"]
).
Constructor
new UAParser([user-agent:string][,extensions:object][,headers:object(since@2.0)]):UAParser
* 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:
let parser = new UAParser("your user-agent here"); // 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 : {}
}
*/
UAParser([user-agent:string][,extensions:object][,headers:object(since@2.0)]):IData
* When you call UAParser
without the new
keyword, it will automatically call getResult()
function and return the parsed results.
returns result object `{ ua: '', browser: {}, cpu: {}, device: {}, engine: {}, os: {} }`

withClientHints():Promise<IData>|Thenable<IData>|IData
* Recently, Chrome limits the information exposed through user-agent and introduces a new experimental set of data called “client-hints”. In browser-environment, obtaining the client-hints data via JavaScript must be done in an asynchronous way. In UAParser
you can chain the result object from get*
method with withClientHints()
to also read the client-hints data from the browser and return the updated data as a Promise
.
// client-side example
(async function () {
let ua = new UAParser();
// get browser data from user-agent only :
let browser = ua.getBrowser();
console.log('Using User-Agent: ', browser);
// get browser data from client-hints (with user-agent as fallback) :
browser = await ua.getBrowser().withClientHints();
console.log('Using Client-Hints: ', browser);
// alternatively :
ua.getBrowser().withClientHints().then(function (browser) {
console.log('Using Client-Hints: ', browser);
});
})();
Along with User-Agent
HTTP header, Chrome also sends this client-hints data by default under Sec-CH-UA-*
HTTP headers in each request. In server-side development, you can capture this extra information by passing the req.headers
to UAParser()
(see examples below). When using withClientHints()
in nodejs environment and browser without client-hints support (basically anything that’s not Chromium-based), it will returns a new object with updated data.
// server-side example
// Suppose we got a request having these HTTP headers:
const request = {
headers : {
'user-agent' : 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36',
'sec-ch-ua-mobile' : '?1',
'sec-ch-ua-model' : 'Galaxy S3 Marketing',
'sec-ch-ua-platform' : 'Android'
}
};
const result1 = UAParser(request.headers); // parse only "user-agent" header
const result2 = UAParser(request.headers).withClientHints(); // update with "sec-ch-ua" headers
console.log(result1.os.name); // "Linux"
console.log(result1.device.type); // undefined
console.log(result1.device.model); // undefined
console.log(result2.os.name); // "Android"
console.log(result2.device.type); // "mobile"
console.log(result2.device.model); // "Galaxy S3 Marketing"
new UAParser(request.headers)
.getBrowser()
.withClientHints()
.then((browser) => {
console.log(browser.toString()); // Chrome 110.0.0.0
});
withFeatureCheck():IData
* This method allows us to examine other features beyond navigator.userAgent
to further improve detection of the following:
- browser : Brave (check for
navigator.isBrave
) - device : iPad (check for
navigator.standalone
&navigator.maxTouchPoints
)
// suppose this code runs on iPad
const withoutFeatureCheck = UAParser();
const withFeatureCheck = UAParser().withFeatureCheck();
console.log(withoutFeatureCheck.device); // { vendor : "Apple", model : "Macintosh", type : undefined }
console.log(withFeatureCheck.device); // { vendor : "Apple", model : "iPad", type : "tablet" }
Extending Regex
If you want to detect something that’s not currently provided by UAParser.js (eg: bots
, specific apps, etc), you can pass a list of regexes to extend internal UAParser.js regexes with your own.
UAParser([uastring,] extensions [,headers:object(since@2.0)])
// Example:
const myOwnListOfBrowsers = [
[/(mybrowser)\/([\w\.]+)/i], [UAParser.BROWSER.NAME, UAParser.BROWSER.VERSION, ['type', 'bot']]
];
const myUA = 'Mozilla/5.0 MyBrowser/1.3';
let myParser = new UAParser({ browser: myOwnListOfBrowsers });
console.log(myParser.setUA(myUA).getBrowser()); // {name: "MyBrowser", version: "1.3", major: "1", type : "bot"}
console.log(myParser.getBrowser().is('bot')); // true
// Another example:
const myOwnListOfDevices = [
[/(mytab) ([\w ]+)/i], [UAParser.DEVICE.VENDOR, UAParser.DEVICE.MODEL, [UAParser.DEVICE.TYPE, UAParser.DEVICE.TABLET]],
[/(myphone)/i], [UAParser.DEVICE.VENDOR, [UAParser.DEVICE.TYPE, UAParser.DEVICE.MOBILE]]
];
const myUA2 = 'Mozilla/5.0 MyTab 14 Pro Max';
let myParser2 = new UAParser({
browser: myOwnListOfBrowsers,
device: myOwnListOfDevices
});
console.log(myParser2.setUA(myUA2).getDevice()); // {vendor: "MyTab", model: "14 Pro Max", type: "tablet"}
Some basic extensions (although not very complete at the moment) can also be found under ua-parser-js/extensions
submodule.
import { UAParser } from 'ua-parser-js';
import { Emails } from 'ua-parser-js/extensions';
const browser = new UAParser(Emails)
.setUA('Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Thunderbird/78.13.0')
.getBrowser();
console.log(browser.name); // Thunderbird

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
