Ionic Framework at the moment not working

Only as information, unless work is being done to ensure that it is currently not possible. I will use Ionic Framework CDN. That happens a lot and I was told to report it in the forum immediately so that the developers could react faster.

TypeError: error loading dynamically imported module undefined p-3df3e749.js:1:14741

Laden des Moduls von “https://cdn.jsdelivr.net/npm/@ionic/core/dist/ionic/p-a5fe3e63.entry.js” wurde auf Grund eines nicht freigegebenen MIME-Typs (“text/plain”) blockiert.

Update its working again.

Do yourself a favour and reference to the exact version of Ionic framework you have developed against (if you haven’t already). If you use the general one, once the CDN gets update with the new framework (Ionic 6 is arriving), then you WILL have things breaking in your site/app

<script type="module" src="https://cdn.jsdelivr.net/npm/@ionic/core@5.4.0/dist/ionic/ionic.esm.js"></script>
    <script nomodule src="https://cdn.jsdelivr.net/npm/@ionic/core@5.4.0/dist/ionic/ionic.js"></script>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@ionic/core@5.4.0/css/ionic.bundle.css" />

Thanks, that’s a good tip, I’ll implement that first thing in the morning.

One more question for the future. Where can I look up all the versions?

No clue - never tried to look for it.
I would check GitHub - ionic-team/ionic-framework: A powerful cross-platform UI toolkit for building native-quality iOS, Android, and Progressive Web Apps with HTML, CSS, and JavaScript. and lookup the changelog
