To prevent production crashes from forgotten Prisma migrations, you need a workflow that enforces creating, deploying, and validating changes to schema.prisma. This ensures migrations are never skipped and the database state remains consistently aligned.

The safest way to deploy a Prisma schema migration is to follow a strict sequence: read the reference, update schema.prisma, generate the migration, verify migration.sql exists, and regenerate the Prisma client to ensure validation and prevent data loss.

Your Prisma client crashes after updating schema.prisma because the migration was likely not created or deployed, causing a mismatch between the client and database. Regenerating the client and validating migration.sql ensures alignment and prevents errors.

Yes, you need to regenerate the Prisma client after creating a migration. Client regeneration is a required step in the safe migration workflow to ensure your application code matches the newly deployed database schema and avoid runtime query errors.

To add fields to a Prisma model without losing production data, update schema.prisma and generate a migration using a safe migration workflow. This process validates the migration.sql file and applies schema changes with minimal risk to existing data.

Managing Prisma migrations manually is error-prone because forgetting to create or deploy migrations can cause production crashes. Without guardrails to ensure migration.sql exists and the client is regenerated, schema changes risk data loss and deployment failures.
