Getting started

Decorator-based entity seeding for TypeORM. Annotate entity properties with @Seed(), then create or persist fully populated entity graphs with a single call — including relations, embedded types, and circular guards. Organize complex seeding scenarios into @Seeder classes with declared dependencies that are automatically ordered and executed.

Installation

typeorm and reflect-metadata are peer dependencies.

npm

npm install @joakimbugge/typeorm-seeder typeorm reflect-metadata

yarn

yarn add @joakimbugge/typeorm-seeder typeorm reflect-metadata

pnpm

pnpm add @joakimbugge/typeorm-seeder typeorm reflect-metadata

Verify these compiler options are enabled in your tsconfig.json — TypeORM requires them and they should already be set:

{
  "compilerOptions": {
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true
  }
}
