Describe your issue

After installing FlyonUI into angular 20.x and 21.x, I am unable to import and use the components.

for example

import { HSAccordion } from "flyonui/flyonui";
Generates a warning in the console with the message

Import "HSAccordion" will always be undefined because the file "node_modules/flyonui/flyonui.js" has no exports [import-is-undefined]

As mentioned in the message, the component is not usable and gives a error in the browser console when the page is loaded.

The html based designs and interactions work find.

I don't have this issues with flyonui integration for angular 19.x.

How can this issue be resolved?

Updates: I just realized that this issue is not present when I run angular without ssr. This issue is not present in angular with ssr in angular v19.
