I would be grateful for ideas.

Answer 1

I don't know how Yii 2 uses scripts, but you can download it like this:

var s = document.createElement('script');
s.src = '/script.js'; // путь до нужного скрипта
s.async = true;
s.onload = s.onreadystatechange = function() {} // функция сработает сразу после загрузки скрипта
document.head.appendChild(s);
