import { Config } from '../src/Config';

@Config('app')
export class AppConfig {
    @IsNumber()
    public port: number = parseInt(process.env.PORT, 10);

    @IsString()
    public serviceId: string = process.env.SERVICE_ID;

Register your config files to ConfigModule

import {ConfigModule} from '@nest-kr/config';

@Module({
    imports: [ConfigModule.forRoot(AppConfig, ...)],
})
export class AppModule {}

Get your config from ConfigService using key

// in bootstrap
import {ConfigService} from '@nest-kr/config';

async function bootstrap(){
    const app = await NestFactory.create(AppModule);
    const configService: ConfigService = app.get(ConfigService);

    const appConfig:AppConfig = configService.get('app');
    ...
}

// in class
@Injectable()
class TestService{

    constructor(private configService: ConfigService){}

    async function test(){
        const appConfig: AppConfig = this.configService.get('app');
    }
}
