Good day - the question is this: is there a ready-made solution that allows for checks like this:

if(mobileBrowser) {} else {/* desktop browser */}

Interested in both the server and the client.

I found only this on php

And in general - who uses what for these purposes?

especially relevant solution to JS.

upd is another option - Yandex Director , but I really wouldn’t like to make unnecessary requests ...
