There are no special consideration other than loading the polyfill to your SPA according to the instructions. Of course as this polyfill requires jQuery make sure that jQuery is loaded before including it.
e.g.
<head>
....
<link rel="stylesheet" href="placeholder_polyfill.min.css">
...
<script src="placeholder_polyfill.jquery.min.combo.js" charset="utf-8"></script>
...
</head>
