Should I use Hammer.js if I only need swipeleft

Question

In my website I only want to open sidebar menu on swipeleft. I don't want to use Hammer.js (7.34KB) only for this functionality. Is there any other option available? I'll use this code to close the menu:

$("#page-content-wrapper").on("touchstart", function() {
      wrapper.removeClass("toggled");
    });

And I'm using this code to open the menu (that I don't wanna use):

  Hammer(document.getElementById("page-content-wrapper")).on("swiperight", function() {
      wrapper.addClass("toggled");
    });
