nest-seederDatabase seeding for NestJS

CLI-first, factory-powered, and type-safe. Seed realistic data with Faker.js in minutes.

🖥️

CLI-first

Run `nest-seed` with zero changes to your app code. Auto-detects your config, scaffolds files with `init`, and lists seeders with `list`.

🏭

Declare realistic data with the `@Factory` decorator. Supports dependent fields, factory inheritance, and per-record overrides.

🔄

TypeORM, Mongoose, Prisma, or anything Nest can inject. You own the seeders — the library wires and runs them.

🎯

Run specific seeders by name, refresh (drop + reseed) in foreign-key-safe order, or preview with `--dry-run`.

📦

Ships modern ESM and CommonJS builds with full TypeScript declarations. Type-safe factories and config.

🧪

The same factories and seeders you run from the CLI work great inside your test suite.
