Hi,
Ionic 4 gives support to all frontend framework including blaze. You just need to add these scripts in the header and you’re done.
Consider Ionic as some third party lib, and you have to include it in the header to make it works.
<script type="module" src="https://cdn.jsdelivr.net/npm/@ionic/core@4.7.4/dist/ionic/ionic.esm.js"></script>
<script nomodule src="https://cdn.jsdelivr.net/npm/@ionic/core@4.7.4/dist/ionic/ionic.js"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@ionic/core@4.7.4/css/ionic.bundle.css"/>
