Prisma

Prisma is an ORM for TypeScript, that allows you to define your database schema and models in a schema.prisma file, and then generate a type-safe client that can be used to interact with your database from your backend.

Check out What is Prisma? to get a better understanding of what Next.js is and how it works.

The Prisma Schema

Every project that uses a tool from the Prisma ORM toolkit starts with a Prisma schema file. The Prisma schema allows developers to define their application models in an intuitive data modeling language. It also contains the connection to a database and defines a generator :

Relational Databases

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


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


model Post {
  id        Int     @id @default(autoincrement())
  title     String
  content   String?
  published Boolean @default(false)
  author    User?   @relation(fields: [authorId], references: [id])
  authorId  Int?
}


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

MongoDB

datasource db {
  provider = "mongodb"
  url = env("DATABASE_URL")
}


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


model Post {
  id        String  @id @default(auto()) @map("_id") @db.ObjectId
  title     String
  content   String?
  published Boolean @default(false)
  author    User?   @relation(fields: [authorId], references: [id])
  authorId  String  @db.ObjectId
}


model User {
  id    String  @id @default(auto()) @map("_id") @db.ObjectId
  email String  @unique
  name  String?
  posts Post[]
}
