Shiny + Firebase + Stripe

[paladinic]

I am in the process of building a shiny app which is meant to sit behind a Firebase auth portal that handles Stripe subscription payments.

Luckily, the library firebase allows one to integrate Firebase easily in shiny apps:

firebase

Also luckily, there is an extension to Firebase for Stripe to handle payments:

Run Payments with Stripe | Firebase Extensions Hub

Combining these seems like the cleanest solution compared to similar approaches such as:

• polished / polishedpayments
• Online payments for data science apps (DSaaS) using R, Shiny, Firebase, Paddle and Google Cloud Functions · Mark Edmondson

While I deeply appreciate these other approaches, I was hoping to leverage the more official solutions described above.

Does anyone know how to integrate the two in shiny (i.e. Firebase + Stripe Extension)?
Are there other solutions to explore that could achieve this?
