# Database Integration — NestJS

Source: https://www.geekswithgeeks.com/en/nestjs/nestjs-database-integration

> Connect NestJS to databases via TypeORM or other ORMs.

## TypeORM setup

Install `@nestjs/typeorm` and `typeorm`. Configure in your root module.

```bash
npm install @nestjs/typeorm typeorm pg
```

## Register with NestJS

Use `TypeOrmModule.forRoot()` to configure the connection.

```typescript
import { TypeOrmModule } from '@nestjs/typeorm';

@Module({
  imports: [
    TypeOrmModule.forRoot({
      type: 'postgres',
      host: 'localhost',
      port: 5432,
      username: 'user',
      password: 'password',
      database: 'mydb',
      entities: [User, Post],
      synchronize: true
    })
  ]
})
export class AppModule {}
```
