Environment और Configuration

Environment variables और per-environment configuration को manage करें।

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

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

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

@Injectable()
export class AppService {
  constructor(private config: ConfigService) {}

  getPort() {
    return this.config.get<number>('PORT') || 3000;
  }
}
