`@pdftron/webviewer` no longer works in `vite-rolldown` version 7.19.0

[chagweyh]

Starting from version 7.19.0, vite-rolldown changed the way default exports are resolved to make it more consistent with other bundlers, such as esbuild and webpack.

This change breaks @pdftron/webviewer. We now see the following error in the console:

Uncaught TypeError: WebViewer is not a function

Looking at https://cdn.jsdelivr.net/npm/@pdftron/webviewer@11.8.0/public/core/webviewer-core.min.js, both exports.default and __esModule are used, which may violate this rule: https://publint.dev/rules#cjs_with_esmodule_default_export.

Additional references:

• [Bug]: Import differences compared to rollup rolldown/rolldown#6438

WebViewer version:
11.8.0

Hi @chagweyh,

Thanks for reaching out with this report. Since this involves the WebViewer core can you submit this via our support page? This will help us triage this better.

We are currently exploring changing to Vite from Webpack so we are investigating some of these issues, your feedback on this is valuable.
