Quick answer

Prisma developer reference

Prisma is a TypeScript-friendly database toolkit and ORM. Production Prisma work starts with schema modeling, generated client usage, migrations, relation loading, transactions, raw-query boundaries, seeding, and database-specific performance checks.

What to learn first

  • •Model relations and constraints clearly in schema.prisma before building application queries around them.
  • •Use migrations deliberately; do not treat push-style development shortcuts as a production release process.
  • •Control relation loading and select/include shape so API handlers do not fetch too much data.

Common pitfalls

  • •Creating a new PrismaClient per request can exhaust database connections in server environments.
  • •Using include everywhere can create large response payloads and hidden query costs.
  • •Raw SQL is sometimes necessary, but it needs parameterization and review at trust boundaries.

schema.prisma is the contract for models, fields, relations, datasource, generator settings, and database mapping.

model User {
  id    Int    @id @default(autoincrement())
  email String @unique
  posts Post[]
}

Key Concepts

  • •Keep schema names aligned with business concepts, not only database convenience.
  • •Use @map and @@map when database names differ from application names.
  • •Review generated migrations before applying them to shared environments.

Relations describe how records connect. Correct relation modeling prevents confusing query shapes and accidental orphaned data.

model Post {
  id       Int  @id @default(autoincrement())
  author   User @relation(fields: [authorId], references: [id])
  authorId Int
}

Key Concepts

  • •Use explicit foreign-key fields so relation ownership is clear.
  • •Choose cascade behavior deliberately for deletes and updates.
  • •Index relation fields used in frequent filters or joins.

Migrations convert schema changes into database changes. Treat them as release artifacts that need review, ordering, and rollback thinking.

npx prisma migrate dev --name add_user_profile
npx prisma migrate deploy

Key Concepts

  • •Use migrate deploy in production-style environments.
  • •Inspect generated SQL before applying risky table or column changes.
  • •Back up and rehearse restores before large schema changes.
