Here is a few ways to check if user is browsering from a mobile browser.
#1. Check `userAgent` (not recomended)
js
// You can add more if you want
const isMobile = /Android|BlackBerry|iPad|iPod|iPhone|webOS/i.test(navigator.userAgent);I don't recommend this approach because the client can send a fake user agent.
#2. Use feature detection
Check if the browser supports the
`pointer:coarse` media query:js
const isMobile = function () {
const match = window.matchMedia('(pointer:coarse)');
return match && match.matches;
};We can't rely on the screen size because the mobile devices are getting bigger.
