During the initial load of your application, you may want to display a loading indicator to convey to the user that something is happening. To do so, you can add the following code directly to your app's index.html
file.
<div class="loader-example">
<svg viewBox="0 0 102 101">
<g fill="none" fill-rule="evenodd">
<g stroke-width="2" transform="translate(1 1)">
<ellipse cx="50" cy="49.421" rx="50" ry="49.421" stroke="#eee"></ellipse>
<path d="M50 98.842c27.614 0 50-22.127 50-49.42C100 22.125 77.614 0 50 0" stroke="#3B6E8F" stroke-opacity=".631"></path>
</g>
</g>
</svg>
</div>
