Как обработать POST-запрос без лишних require'ов?

<form enctype="application/x-www-form-urlencoded" method="POST" action="/submit">
	<input type="text" name="name" value="Вася"><br>
	<input type="text" name="surname" value="Пупкин"><br>
	<input type="submit" value="Send">
</form>

if(req.url == '/submit' && req.method == 'POST') {
		req.on('data', function(data){
			var s = decodeURIComponent(data.toString());
			console.log(s);
			
			var obj = {};
			var arr = s.split('&');
			arr.forEach( el => {
				var a = el.split('=')
				obj[a[0]] = a[1];
			});
			console.log(obj);
		});
		return res.end('POST');
	}

name=Вася&surname=Пупкин
{ name: 'Вася', surname: 'Пупкин' }
