@nestjs-dash/db-seeder-nestjs

Optional NestJS integration for @nestjs-dash/db-seeder: DbSeederModule.forRoot/forRootAsync + an injectable DbSeederService. Core stays a plain, zero-NestJS-dependency library — this package is the framework glue, kept separate the same way @nestjs-dash/adapter and @nestjs-dash/nestjs are.

📖 DB Seeder NestJS integration docs

Install

pnpm add @nestjs-dash/db-seeder @nestjs-dash/db-seeder-nestjs @nestjs-dash/db-seeder-typeorm
# or the -prisma / -drizzle / -mongodb adapter instead of -typeorm

Usage

import { DbSeederModule, DbSeederService } from '@nestjs-dash/db-seeder-nestjs';

@Module({
  imports: [
    DbSeederModule.forRootAsync({
      useFactory: (dataSource: DataSource) => ({ adapter: 'typeorm', connection: dataSource }),
      inject: [DataSource],
    }),
  ],
})
export class AppModule {}

@Injectable()
export class SeedCommand {
  constructor(private readonly dbSeeder: DbSeederService) {}

  run() {
    return this.dbSeeder.seed(
      { format: 'json', data: [{ name: 'Ada Lovelace' }] },
      { name: 'authors', columns: [{ name: 'name', required: true }] },
    );
  }
}

DbSeederModule dynamically imports whichever @nestjs-dash/db-seeder-<adapter> package matches the configured adapter option, so only the one you actually install needs to be present — the other three are optional peer dependencies.
