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.

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

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

output = "../generated"

Creates: generated/client

Monorepo

output = "../../packages/database/generated"

Same directory as schema

output = "./generated"

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)

datasource db {
  provider  = "postgresql"
  url       = env("DATABASE_URL")
  directUrl = env("DIRECT_URL")
}

After (v7)

datasource db {
  provider = "postgresql"
  // URLs configured in prisma.config.ts
}

// prisma.config.ts
export default defineConfig({
  datasource: {
    url: env('DATABASE_URL'),
    directUrl: env('DIRECT_URL'),
    shadowDatabaseUrl: env('SHADOW_DATABASE_URL'),
  },
})

Full Example

v6 Schema

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

datasource db {
  provider  = "postgresql"
  url       = env("DATABASE_URL")
  directUrl = env("DIRECT_URL")
}

v7 Schema

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

datasource db {
  provider = "postgresql"
}

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"]
}
