Hi Replit team 
I’ve just published a production app built on Replit and would appreciate a quick sanity check or best-practice feedback on the deployment setup.
Stack:
• Replit Deployments (public app)
• Firebase Authentication (Google OAuth)
• Firestore
• Express backend + frontend served from the same deployment
What’s working:
• Google sign-in works on the published domain
• Users can log out and log back in
• Data persists correctly
• App is live at: https://travent-card-wallet.replit.app
What I’d love feedback on:
• Is this the recommended pattern for OAuth + Firebase on Replit?
• Any deployment or domain pitfalls I should watch for before adding a custom domain?
• Anything I should adjust for production readiness or scaling?
I’m not looking for a full code review—just confirmation that the architecture and deployment approach align with Replit best practices.
Thanks in advance
