import { ConfigModule } from '@nestjs/config';

@Module({
  imports: [
    ConfigModule.forRoot({
      isGlobal: true,
      envFilePath: '.env',
    }),
  ],
})
export class AppConfigModule {}

### Admin Service Example

Source: https://github.com/taozhi1010/nest-admin/blob/master/admin-vue3/html/ie.html

A basic implementation of an AdminService in NestJS, responsible for the core business logic of the admin module. This service would typically be injected into controllers.

```typescript
import {
  Injectable
} from '@nestjs/common';

@Injectable()
export class AdminService {
  getAdminData(): string {
    return 'Admin data from service';
  }
}
```
