How to automatically generate Joi schemas from your Prisma schema

I'm sure you have built an API before, where you had to manually create a Joi schema for every endpoint. It was repetitive and time-consuming. But not anymore with the help of the Prisma generator I have recently built.

Here's what you need to do:

1- Install the generator

• Using npm

 npm install prisma-joi-generator

• Using yarn:

 yarn add prisma-joi-generator

2- Add the generator to your Prisma schema

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

3- Run npx prisma generate for your schema(or the example below)

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?
}

Now you will have all possible Joi schemas generated for you!
