Schema Changes

Prisma v7 introduces a new prisma-client generator. Update your generator block and import paths accordingly.

Generator Provider

Before (v6)

generator client {
  provider = "prisma-client-js"
  engineType = "binary"  // or "library"
}

After (v7)

generator client {
  provider = "prisma-client"
  output   = "../generated"
}

Key Changes

1. Provider name

Use prisma-client in Prisma v7.

2. Output is required (for prisma-client)

The output field is mandatory when using prisma-client. Prisma Client no longer generates to node_modules with this generator.

3. Engine type removed

engineType is removed in Prisma v7. Remove any engineType setting from your generator block.

Example Output Paths (prisma-client)

Standard project

Creates: generated/client

Monorepo

Same directory as schema

Creates: prisma/generated/client

Datasource Block

The url, directUrl, and shadowDatabaseUrl values now live in prisma.config.ts in Prisma v7. Keep only the provider in schema.prisma:

Before (v6)

After (v7)

Full Example

v6 Schema

v7 Schema

After Schema Changes

1. Run prisma generate:

   npx prisma generate

2. Update imports throughout your codebase:

   // Before (prisma-client-js)
   import { PrismaClient } from '@prisma/client'
    
   // After (prisma-client, output = "../generated")
   import { PrismaClient } from '../generated/client'

3. Update .gitignore (if using prisma-client output):

   generated

Preview Features

Preview features work the same:

generator client {
  provider        = "prisma-client"
  output          = "../generated"
  previewFeatures = ["relationJoins", "fullTextSearch"]
}
