@jmondi/prisma-generator-nestjs-graphql

Generate @nestjs/graphql entities and create/update inputs

Install

pnpm add @jmondi/prisma-generator-nestjs-graphql

Usage

generator custom_generator {
  provider           = "generate-nestjs-models"
  clientPath         = "@prisma/client"
  output             = "../generated"
}

See the generated examples for sample output.

Why?

The special sauce here is the type-safe constructors.

  constructor(model: UserConstructor) {
    this.id = model.id ?? uuid();
    this.email = model.email;
    this.passwordHash = model.passwordHash ?? null;
    this.tokenVersion = model.tokenVersion ?? 0;
    this.lastLoginAt = model.lastLoginAt ?? null;
    this.createdIP = model.createdIP;
    this.createdAt = model.createdAt ?? new Date();
    this.updatedAt = model.updatedAt ?? null;
    this.posts = model.posts ?? null;
  }

Configuration

The following are all the default options, feel free to change them to your liking.

generator custom_generator {
  provider           = "generate-nestjs-models"
  clientPath         = "@prisma/client"
  output             = "../generated"
  modelPrefix        = "@prisma/client"
  modelPrefix        = ""
  modelSuffix        = ""
  modelFileSuffix    = ""
  useAbstractModels  = true
  compileJs          = false
  withPaginatorInput = false
}

Custom Entities

Create your own entities by extending the generated base entities.

export class User extends BaseUser {}

Extend your custom entities with additional fields.

export abstract class UserToken extends BaseUserToken {
  @Field(() => User, { nullable: true })
  user!: null | User;

  constructor(props: UserTokenConstructor) {
    props.user = props.user ? new User(props.user) : undefined;
    super(props);
  }
}
