QLayout crashes with UMD prod build (2.19.x) — isRuntimeSsrPreHydration is undefined in setup()

[lianee]

What happened?

Using in a UMD setup with an inline HTML template crashes with:

TypeError: Cannot read properties of undefined (reading 'value')
at setup (quasar.umd.prod.min.js:12:284707)
The crash is in QLayout.setup(), where it accesses isRuntimeSsrPreHydration.value. In the production UMD build, this variable is undefined at the time setup() runs.

The same code works with:

Quasar 2.18.7 prod build ✓
Quasar 2.19.x dev build (quasar.umd.js) ✓
This is a regression introduced in 2.19.0 (rolldown build toolchain).

What did you expect to happen?

Page renders without error.

Workaround

Use the dev build instead of the prod build:

<script src="https://cdn.jsdelivr.net/npm/quasar@2.19.2/dist/quasar.umd.js"></script>

Hi,

Looking into it.
However, there is no quasar.umd.prod.min.js. Only quasar.umd.prod.js

Our dev setup shows it working without errors. Can you supply a minimal reproduction html file pls? Will look deeper into this, however it's extremely hard to pinpoint where exactly the problem is.

Seems like jsdelivr creates that one. Do NOT use it. quasar.umd.prod.js is already minified.

Managed to reproduce it. Investigating further.

Figured it out.
A bug in rolldown. Quasar v2.19.0/1/2 were built with rolldown 1.0.0-rc.9. Latest rolldown rc.13 fixed the compile issue.

All we have to do is do another Quasar UI release. This will happen on Monday.
