Tue, 07 Dec 2021 00:00:00 +0000

Prisma provides type-safe database access, migrations, and a visual data browser-popular in TypeScript full stack projects.

Schema Definition

model User {
  id        String   @id @default(cuid())
  email     String   @unique
  posts     Post[]
  createdAt DateTime @default(now())
}

model Post {
  id       String @id @default(cuid())
  title    String
  author   User   @relation(fields: [authorId], references: [id])
  authorId String
}

Queries

const users = await prisma.user.findMany({
  include: { posts: true },
  where: { email: { contains: '@company.com' } },
});

Migrations

npx prisma migrate dev applies schema changes in development. Use prisma generate after schema edits to refresh the client.
