jQuery code need to translate to vanilla so I can use in Angular

I have this code on a template and I'm transfering the code to Angular 4 but it doesn't like the $ on jquery so I need a way to either be able to use it on Angular 4 or just translate it to pure js so I can use it.

Here's the code:

$('#toggle-btn').on('click', function (e) {

        e.preventDefault();

        if ($(window).outerWidth() > 1194) {
          $('nav.side-navbar').toggleClass('shrink');
          $('.page').toggleClass('active');
        } else {
          $('nav.side-navbar').toggleClass('show-sm');
          $('.page').toggleClass('active-sm');
        }
      });

How can I do this?
