A small trick to check if youtube video exist with its id.

ValidateYoutubeVideoId.js

function validVideoId(id) {
		var img = new Image();
		img.src = "http://img.youtube.com/vi/" + id + "/mqdefault.jpg";
		img.onload = function () {
			checkThumbnail(this.width);
		}
	}

	function checkThumbnail(width) {
		//HACK a mq thumbnail has width of 320.
		//if the video does not exist(therefore thumbnail don't exist), a default thumbnail of 120 width is returned.
		if (width === 120) {
			alert("Error: Invalid video id");
		}
	}

Thank you for the trick, saved my day

you beauty! I've found nothing else that works.

thanks man it works

my approach is this btw :
im using venilla js.

const is_valid_ytd_video = async (id) => {
let response = await axios.request("https://www.youtube.com/embed/" + id)
return response.data.toLowerCase().includes("Video unavailable".toLowerCase());
}
