Files in "src/js" do not compile

[alphex]

I have 5 3rd party library files in the src/js directory.

When I run npm start they do not compile in to the build/js/scripts.js file.

There are no logs indicating any errors...

not sure where to start.

!function(){for(var a=document.querySelectorAll("a"),i=0;i<a.length;i++)a[i].host!==location.host&&(a[i].setAttribute("target","_blank"),a[i].setAttribute("rel","noopener noreferrer"))}();

Thoughts?
Thanks.
