[🐞] Qwik - Build is Aggressively Treeshaking with Firebase

Which component is affected?

Qwik Rollup / Vite plugin

Describe the bug

I've been working with the Firebase team to get Firebase working on Edge functions.

https://github.com/firebase/firebase-js-sdk/issues/8355

Firebase now works on ever single Framework, even in Edge Environments (Bun, Deno, Cloudflare)... except on Qwik.

Reproduction

https://qwik-firebase-test.vercel.app/

Steps to reproduce

Here is issue on Firebase with deployment instructions:

https://github.com/firebase/firebase-js-sdk/issues/8506

Repo: GitHub

Demo with error: Vercel Edge

System Info

Vercel Edge (no way to currently test this on Vercel Functions as there is not a Plugin)

Additional Information

Here is what the Firebase team said after agressive testing:

I was able to reproduce the problem. It appears that something in the build pipeline is aggressively tree shaking portions of the Firebase JS SDK when it packages it for the edge runtime. The "service" mentioned in the log file is that fact that Auth cannot properly register itself with the instance of FirebaseApp (or FirebaseServerApp). This is due to the hooks it would use to register itself with the instance of App are inexplicitly missing from the SDK implementation.

Small Chance could be related to: https://github.com/QwikDev/qwik/issues/6322

Note: This could also be a Vercel Edge Plugin problem, but I'm not sure how the build process works.

Start with the Qwik Rollup/Vite plugin and reproduce the failure using the linked qwik-firebase-test repository and Vercel Edge demo. Compare the build output and runtime behavior with Firebase issue 8506; done means Firebase Auth initializes correctly in the Qwik Edge deployment without required SDK portions being tree-shaken.
