Not installing package, but using url as source

[lbreguet]

I'm trying to use the plugin in a SharePoint website, and I'm trying to use the plugin in the following form:

require(["https://github.com/tsuyoshiwada/sweet-scroll/blob/master/sweet-scroll.js"], function() {
      var scroller = new SweetScroll({
            vertical: false,
            horizontal: true,
      }, '#container');
})

However, I keep getting an error that SweetScroll is undefined and it's breaking the rest of my script.
