<h1>bottle-service (tested on Chrome Desktop only)</h1>
<p>This page can rewrite itself inside a ServiceWorker behind this website.
Try adding a couple of DOM nodes using a button below, then reload the page.
Notice that the page <strong>arrives with new DOM nodes</strong> to the browser,
thus there is no blinking / initial pause. If you inspect the fetched page's source
in the Network tab you will see the updated HTML on each reload.</p>
<p>The self-rewriting portion is below</p>
<!-- terrible hack to quickly remove inner contents - set the id on the closing tag -->
<div id="app">some content here already</div id="app">
<div class="controls">
Controls
<button id="add">Add new DOM node to the list</button>
<button id="print">Print current bottle contents</button>
<button id="clear">Clear cached HTML</button>
<ul>
<li>"Add" - inserts a new item into the rewritable portion of this page. Stores the dynamic
HTML portion in the ServiceWorker for the future reload</li>
<li>"Print" - prints what is currently stored for the rewritable portion of the page in the
ServiceWorker (open browser console to view)</li>
<li>"Clear" - clears the stored HTML from the ServiceWorker storage</li>
</ul>
</div>
<div class="instructions">
<h3>How to use</h3>
<p>Load the page first - I assume you have already done this, if you are reading this</p>
<p>Click "Add ..." button several times, you should see new items in the list.</p>
<p>Reload the page - you should see the items you have added right away - they are part
of the loaded page, <strong>not added dynamically later</strong>. You can confirm
this by inspecting the downloaded page's source or the contents of the page in the Network tab.</p>
<h4>Note</h4>
<p>Open browser console to see any messages / errors</p>
