Prisma 7 and the Architecture Wake-Up Call

Prisma 7 had other plans.

Suddenly I was hit with errors like:

The datasource property url is no longer supported in schema files.

What changed?

Prisma 7 introduced stricter rules around:

• Environment handling

• Database URLs

• Serverless compatibility

My old mental model no longer worked.

The new setup

I had to rethink the architecture:

1. Created prisma.config.ts to handle migrations

2. Used Driver Adapters with @prisma/adapter-pg

3. Manually passed a connection pool into the Prisma Client

Instead of Prisma magically handling everything, I became explicit about how connections are created and managed.
