UAParser.jsHow to Detect Windows 11
It's currently impossible to detect Windows 11 only from user-agent data, since most browser vendors are unknowingly cap the Windows version at 10.
Luckily, there is a workaround by utilizing client hints feature:
js
const uap = new UAParser();
let os = uap.getOS();
console.log('Based on user agent: ', os);
// { name: "Windows", version: "10" }
uap.getOS().withClientHints().then(os => {
console.log('Based on client hints', os);
// { name: "Windows", version: "11" }
});WARNING
Client hints feature is only supported in Chromium-based browsers (Chrome, Edge, etc.). In other browsers like Firefox and Safari, withClientHints() gives no effect to the result, thus it will still be detected as Windows 10.
