browserify-shim, expose jquery from cdn, require('backbone')

The setup below has been adapted from this browserify-shim example.

The code can simply require(jquery) because browserify-shim will replace these with window.jQuery, expecting that it will have been exposed there, loaded from a CDN via a <script> tag. So far, this part works.

The key difference with the original example is that this code also wants to require('backbone') (a regular npm install). Backbone also does a require('jquery') and I was expecting this to just work too.

Except, that it doesn't, as this statement will demonstrate:

npm install

result:

> expose-jquery@0.0.0 install /tmp/expose-jquery
> browserify -d . > bundle.js

Error: Cannot find module 'jquery' from '/tmp/expose-jquery/node_modules/backbone'

I expect a perspective exist from which this makes sense, however I fail to see it.

I forgot what issue I created this gist for, but likely it is this one.
