ua-parser-js
Advanced tools
Detect Browser, Engine, OS, CPU, and Device type/model from User-Agent & Client Hints data. Supports browser & node.js environment
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.
The most comprehensive, compact, & up-to-date isomorphic JavaScript library to detect user's Browser, Engine, OS, CPU, and Device type/model. Runs either in browser (client-side) or node.js (server-side).
