Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.
ua-parser-js
Advanced tools
Package description
The ua-parser-js package is a utility for parsing user agent strings. It can be used to extract detailed information about the browser, engine, OS, CPU, and device from the user agent string provided by the client's browser.
Browser Detection
This feature allows you to detect the browser name and version from the user agent string.
const UAParser = require('ua-parser-js');
const parser = new UAParser();
const browser = parser.getBrowser();
console.log(browser);
Operating System Detection
This feature enables you to determine the operating system and its version from the user agent string.
const UAParser = require('ua-parser-js');
const parser = new UAParser();
const os = parser.getOS();
console.log(os);
Device Detection
With this feature, you can identify the device type, vendor, and model from the user agent string.
const UAParser = require('ua-parser-js');
const parser = new UAParser();
const device = parser.getDevice();
console.log(device);
Engine Detection
This feature allows you to extract the layout engine name and version from the user agent string.
const UAParser = require('ua-parser-js');
const parser = new UAParser();
const engine = parser.getEngine();
console.log(engine);
CPU Architecture Detection
This feature provides information about the CPU architecture from the user agent string.
const UAParser = require('ua-parser-js');
const parser = new UAParser();
const cpu = parser.getCPU();
console.log(cpu);
The 'device' package is another npm package that allows you to parse user agent strings to determine device type (phone, tablet, desktop, etc.). It is simpler than ua-parser-js and does not provide detailed information about browser, engine, or OS.
The 'platform' package is used for parsing and interpreting user agent strings. It provides information about the operating system, browser, and device in a structured format. It is similar to ua-parser-js but has a different API and may offer different levels of detail in the results.
Bowser is a browser detection library that is similar to ua-parser-js. It focuses on identifying browser type, version, and engine. It also provides methods to check if the browser matches certain criteria, which can be useful for feature detection and browser-specific adjustments.
Readme
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.

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
// 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);
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"}
$ npm run test

Do you use & like UAParser.js but you don’t find a way to show some love? If yes, please consider donating to support this project. Otherwise, no worries, regardless of whether there is support or not, I will keep maintaining this project. Still, if you buy me a cup of coffee I would be more than happy though :)
