I also created an issue on https://forum.primefaces.org/viewtopic.php?f=142&t=66480

Current behavior
I purchased diamond project and try to use it with vite.js compiler recently introduced in https://github.com/primefaces/primevue-quickstart-vite.
npm run dev then error shown:
Please import the top-level fullcalendar lib before attempting to import a plugin.

What is the motivation / use case for changing the behavior?
This should update outdated dependencies on Diamond Premium Template and run with Vite.js perfectly.

Please tell us about your environment:

Thank you @Aysnine !
But I had this error. How can you solve this?
Uncaught (in promise) TypeError: chart_esm_exports is not a constructor

@TuguldurJ
Sorry, some error about chart. I'm not aware of this component.

[TuguldurJ]

It was related to issue #1142. Chart.js v3.0 is not supported yet.

[cagataycivici]

Charts also have this issue with Vite, we'll see if there is something we can do on our end.

[cagataycivici]

Closing as FullCalendar is deprecated in favor of the official component.

@cagataycivici can you elaborate on what do you mean as the official component? I'm working with Diamond theme and having exactly this issue.

[cbutler90]

Having same issue. Still no vite support?

[cbutler90]

For anyone looking for a resolution:

import '@fullcalendar/core/vdom';

in the component file add "vdom" as seen above
