Creating Yahoo/Twitter/YouTube-like widgets from MVC app?

[basememara]

I have a full-fledged MVC app written in Ext JS 4. One of my views is a simple grid retrieving data from JSONP. My question is how can I provide this as Javascript widgets for my partners to use on their own websites? I obviously would not want to deploy my whole app to their website, but I would like to give them a single line of Javascript code that will render the grid and data coming from my central MVC app hosted on my side.. much like if I wanted to add a YouTube widget onto my website (I would only cut-and-paste a few lines of code onto my site). Any advice or experience would be greatly appreciated!

Use namespacing... the name of a class dictates the folder it should be in.

What if that folder is on a remote site.. can a namespace refer to a remote file?

Haven't tried but I don't I don't see why not. Just have to make sure Ext.Loader doesn't do Ajax calls, <script> tags are able to. SDK Tools use PhantomJS which is just a headless browser really.

Changing the appFolder to a remote path seemed to work:

~/app.js

Ext.application({
  name: 'MyApp',
  appFolder: 'http://remotesite.com/app'
...
});

Then on WordPress for example, I would add an HTML widget onto my page like this:

<link rel="stylesheet" type="text/css" href="http://remotesite.com/lib/sencha/ext-4.0.7-gpl/resources/css/ext-all.css" />
<link rel="stylesheet" href="http://remotesite.com/css/styles.css" type="text/css" />
<script type="text/javascript" src="http://remotesite.com/lib/sencha/ext-4.0.7-gpl/ext-all-debug-w-comments.js"></script>
<script type="text/javascript" src="http://remotesite.com/app.js"></script>
<div id="dataview-products"></div>

This actually worked and rendered my DataView in the WordPress site, but does not seem so elegant. Also it makes the widget in full screen for some reason so it hides most of the WordPress site instead of being self-contained in the WordPress HTML widget. Any input or samples would be greatly appreciated.
