This will load jQuery from a CDN:

<script src=http://requirejs.org/docs/release/2.1.5/comments/require.js></script>

<script type=text/javascript>

  require.config({

    paths: {

        jquery: https://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min

    },

    waitSeconds: 40

  });

</script>



<div id=message>hello</div>



<script type=text/javascript>

  require( [jquery],

    function ($) {

      alert($.fn.jquery + n + $(#message).text());

    }

  );

</script>

Fiddle Here.

This page from the requirejs docs shows how to eliminate a path from the optimised build. Basically use the empty: scheme. Excerpt here:

node ../../r.js -o name=main out=main-built.js baseUrl=. paths.jquery=empty:
