how to import packages from npm

[pjebs]

I am trying to use Sortable from within React.

The instructions state:

npm install sortablejs --save
=====
and then:

<ul id="items">
	<li>item 1</li>
	<li>item 2</li>
	<li>item 3</li>
</ul>

var el = document.getElementById('items');
var sortable = Sortable.create(el);

I can't seem to load the npm library.
Since it's chrome based, it doesn't understand require( )

Is there any instructions for how to "reactify" non-react libraries from within this package?
