Usage

1- Star this repo 😉

2- Add the generator to your Prisma schema

generator zod {
  provider = "prisma-zod-generator"
}

3- Enable strict mode in tsconfig as it is required by Zod, and considered a Typescript best practice

{
  "compilerOptions": {
    "strict": true
  }
}

4- Running npx prisma generate for the following schema.prisma

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

model Post {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  title     String
  content   String?
  published Boolean  @default(false)
  viewCount Int      @default(0)
  author    User?    @relation(fields: [authorId], references: [id])
  authorId  Int?
  likes     BigInt
}

will generate the following files

5- Use generated schemas somewhere in your API logic, like middleware or decorator

import { PostCreateOneSchema } from './prisma/generated/schemas/createOnePost.schema';

app.post('/blog', async (req, res, next) => {
  const { body } = req;
  await PostCreateOneSchema.parse(body);
});

Additional Options

Use additional options in the schema.prisma

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