bug: Hydration Warnings

[tomosovich]

Provide environment information

"initVersion": "7.26.0"

Describe the bug

A lot of hydration warnings on a fresh run of the scaffold, suppressing the hydration warning didn't change anything. And this bug doesn't happen when deployed to vercel.

Reproduction repo

NA

To reproduce

Scaffold out the build (Prisma, authJS, tailwind)

Additional information

I believe this is happening due to the browser check when establishing the base URL. Compare the following:

function getBaseUrl() { if (typeof window !== "undefined") return ""; if (process.env.VERCEL_URL) return https://${process.env.VERCEL_URL}; return http://localhost:${process.env.PORT ?? 3000}; }

When I change the code to

function getBaseUrl() { if (document) return ""; if (process.env.VERCEL_URL) return https://${process.env.VERCEL_URL}; return http://localhost:${process.env.PORT ?? 3000}; }

The error clears up. Is there any downside to using document instead of type window to establish where the code is being executed?

I can share a repo if needed, and if you'd like me to submit a PR, it's a pretty small changes so anyone can do it.
