By default, gtype follow the same basic rule as prisma generate, eg: mark optional for all property when making xxUpdateInput. You can change most of the them in tealina.config.mjs

// @ts-check
import { defineConfig } from 'tealina'

export default defineConfig({
  gtype:{
    // ...
  }
})

// @ts-check
import { defineConfig } from 'tealina'

export default defineConfig({
  gtype:{
    // ...
  }
})

Partial Overwrite

Exlude the id property

tealina.config.mjs

{
    overwrite: {
      excludeProps: [
        {
          blockName: '*',// '*' for all model and type you declare
          keyword: 'model',
          kind: 'CreateInput',
          predicate: p => p.name === 'id',
        },
      ],
    },
}

{
    overwrite: {
      excludeProps: [
        {
          blockName: '*',// '*' for all model and type you declare
          keyword: 'model',
          kind: 'CreateInput',
          predicate: p => p.name === 'id',
        },
      ],
    },
}

schema.prisma

model Category {
  id           Int    @id @default(autoincrement())
  categoryName String
  description  String

  products Product[]
}

model Category {
  id           Int    @id @default(autoincrement())
  categoryName String
  description  String

  products Product[]
}

types/pure.d.ts

 interface Category {
    categoryName: string
    description: string
  }

 interface Category {
    categoryName: string
    description: string
  }

Type remap

Type remap is more straightforward than overwrite, and effect all kind,(model,type,xxCreateInput,xxUpdateInput,xx)

{
    typeRemap: type => {
      switch (type) {
        case 'Date':
          return 'number | string'
        //  ....
        default:
          // retrun null fallback to default stategy
          return null
      }
    },
}

{
    typeRemap: type => {
      switch (type) {
        case 'Date':
          return 'number | string'
        //  ....
        default:
          // retrun null fallback to default stategy
          return null
      }
    },
}

The default type Map

/** https://www.prisma.io/docs/reference/api-reference/prisma-schema-reference#model-field-scalar-types */
const justMap = new Map<string, string>([
  ['BigInt', 'bigint'],
  ['Int', 'number'],
  ['Float', 'number'],
  ['Decimal', 'number'],
  ['String', 'string'],
  ['DateTime', 'Date'],
  ['Boolean', 'boolean'],
  ['Json', 'JsonValue'],
  ['Bytes', 'Buffer'],
])
