library23.2.1jsnpmunverified

Generate NestJS GraphQL object types, inputs, args, and enums from a Prisma schema file. Current stable version is 23.2.1. It integrates with @nestjs/graphql and is released regularly. Key differentiators: generates only necessary imports, combines nested/nullable filters, and avoids generating resolvers (application-specific). It supports a structured JavaScript config file instead of flat schema keys, and provides options for decorators, custom imports, and scalar types. Requires @prisma/generator-helper and identity-type as peer dependencies.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

ExternalConfig

✓ import { ExternalConfig } from 'prisma-nestjs-graphql'

✗ import ExternalConfig from 'prisma-nestjs-graphql'

Named export for TypeScript config file type. Default export is the config factory function.

default (config export)

✓ export default { output: '../src/@generated' }

✗ module.exports = { output: '../src/@generated' }

Config file must use ESM default export (type: 'module' in package.json or .mjs extension).

Generated types (e.g., User, UserCreateInput)

✓ import { User } from './@generated/user/user.model'

✗ import { User } from '@prisma/client'

Generated types are output to the configured output directory, not from @prisma/client. The exact path depends on outputFilePattern.

Shows basic usage: add generator to schema.prisma, run prisma generate, and import generated types.

// schema.prisma generator nestgraphql { provider = "prisma-nestjs-graphql" output = "../src/@generated" } model User { id Int @id @default(autoincrement()) email String @unique name String? posts Post[] } model Post { id Int @id @default(autoincrement()) title String content String? author User? @relation(fields: [authorId], references: [id]) authorId Int? } // Run: npx prisma generate // Then use in NestJS: import { ObjectType } from '@nestjs/graphql'; import { User } from './@generated/user/user.model'; @ObjectType() export class UserWithPosts extends User { @Field(() => [Post]) posts: Post[]; }

Debug

Known issues

breakingConfig file format changed from underscore-delimited keys to structured JS objects. Old flat keys are deprecated and may be removed in future versions.

fix

Migrate to configFile approach: create prisma/nestgraphql.config.mjs and move all options there as structured objects.

affects: <23.0.0

deprecatedUsing underscore-delimited keys (fields_Validator_from, decorate_1_type, etc.) directly in schema.prisma is deprecated.

fix

Use a structured config file as shown in the README.

affects: >=23.0.0

gotchaThe output path in configFile is relative to the config file, not the schema file. If defined in schema.prisma, it's relative to the schema file.

fix

Use absolute paths or ensure relative path is correct for your project structure.

affects: >=23.0.0

gotchaConfig file must use ESM default export (export default) and be named .mjs or have 'type': 'module' in package.json.

fix

Use .mjs extension or set 'type': 'module' in package.json.

affects: >=23.0.0

gotchaAdditional graphql scalar types (graphql-type-json, prisma-graphql-type-decimal) must be installed manually if models use Decimal or Json types.

fix

Run: npm install graphql-type-json prisma-graphql-type-decimal

affects: all

Errors

Common errors & fixes

Error: Generator 'nestgraphql' failed: Could not find generator options...

Missing or misconfigured configFile or output path.

fix

Ensure output path is correctly specified and configFile points to a valid .mjs file.

Cannot find module 'identity-type'

Missing peer dependency identity-type.

fix

Run: npm install identity-type --save-dev

Unknown type 'Decimal'. Please install prisma-graphql-type-decimal

Prisma model uses Decimal type but the scalar type is not registered.

fix

Install prisma-graphql-type-decimal and register in GraphQL module.
