# UAParser.js 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). # Overview ```js import { UAParser } from 'ua-parser-js'; // 1. Problem: // Imagine getting this wild user-agent string from a visitor: const ua = `Mozilla/5.0 (Linux; Android 10; STK-LX1 Build/HONORSTK-LX1; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/110.0.5481.153 Mobile Safari/537.36 musical_ly_2022803040 JsSdk/1.0 NetType/WIFI Channel/huaweiadsglobal_int AppName/musical_ly app_version/28.3.4 ByteLocale/en ByteFullLocale/en Region/IQ Spark/1.2.7-alpha.8 AppVersion/28.3.4 PIA/1.5.11 BytedanceWebview/d8a21c6`; // Note: this is a real user-agent (what???) // 2. Solution: // Just pass the complex user-agent string to `UAParser` const parser = new UAParser(ua); // 3. Result: // And voila! console.log(parser.getBrowser()); // { name : "TikTok", version : "28.3.4", major : "28", type: undefined } console.log(parser.getCPU()); // { architecture : undefined } console.log(parser.getEngine()); // { name : "Blink", version : "110.0.5481.153" } console.log(parser.getDevice()); // { type : "mobile", vendor : "Huawei", model : "STK-LX1" } console.log(parser.getOS()); // { name : "Android", version : "10" } console.log(parser.getResult()); /* { ua: "Mozilla/5.0 (Linux; Android 10; STK-LX1 Build/HONORSTK-LX1; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/110.0.5481.153 Mobile Safari/537.36 musical_ly_2022803040 JsSdk/1.0 NetType/WIFI Channel/huaweiadsglobal_int AppName/musical_ly app_version/28.3.4 ByteLocale/en ByteFullLocale/en Region/IQ Spark/1.2.7-alpha.8 AppVersion/28.3.4 PIA/1.5.11 BytedanceWebview/d8a21c6", browser: { name: "TikTok", version: "28.3.4", major: "28" }, cpu: {}, device: { type: "mobile", model: "STK-LX1", vendor: "Huawei" }, engine: { name: "Blink", version: "110.0.5481.153" }, os: { name: "Android", version: "10" } } */ // 4. Conclusion: // The visitor is browsing from a TikTok app using an Android-powered Huawei device // Phew!
