H. Query 연습하기 강의 데이터를 "강의 보는 곳에 올려 놓겠다" 고 하셨는데, 거기가 어디인가요?

프록시 설정하고 응답요청했는데 console.log(요청)도 안되고 데이터자체가 안 받아와지는데 왜 그럴까요..?

User가 작성한 Blog를 삭제하게 되면 Blog 내부에 있는 Array도 같이 삭제되지 않나요? Blog를 deleteMany를 통해서 삭제한 이후에 추가로 updateMany를 통해서 Blog에 있는 comment를 pull해주는 이유가 궁금합니다

log를 찍어봤는데 env가 undifine으로 아예 불러오지를 못하는데 제가 간과한게 있을까요?

2종류의 user테이블a_user, b_user 테이블을 가지고 있는데 각 유저테이블에 대해 jwt 검증을 나눠서 하고싶은데..아무리해도 안되는데 팁이 있을까요

async existsByEmail(email: string): Promise<boolean> { try { const result = await this.catModel.exists({ email }); return result; } catch (error) { throw new HttpException('db error', 400); } } 에서 return result부분에서 오류가 발생합니다. src/cats/cats.repository.ts:20:7 - error TS2322: Type 'Pick<Document<Cat, any, any>, "_id">' is not assignable to type 'boolean'.   20       return result;          ~~~~~~~~~~~~~~exists() 따라가 보면 리턴타입이 boolean이 아닌거 같은데 어떤 부분을 확인해 보면 좋을까요?   console.log로 result를 찍어보면  { _id: new ObjectId~~~} 가 나옵니다.

안녕하세요! 강의 잘듣고있습니다.!! PositiveIntPipe pipe를 만들때도 의존성 주입을 해야하기 때문에 @Injectable()를 사용하신건가요?? 만약 맞다면 사용한 이유가 궁금합니다.!!( @Injectable 를빼도 작동이 잘되고 파이프도 의존성을 주입해야하나? 라는 궁금증이 있어서 남깁니다!) 감사합니다!

안녕하세요.  .env에 MONGODB_URI를 못 읽어서 계속 mongodb connect 실패가 발생하고 있습니다. 혹시나 하여 app.modules.ts 에서 @Modules 앞 뒤로 MONGODB_URI를 콘솔로 찍어봤는데 @Modules 전에는 값이 안나오고 이후에는 잘 출력되는데요.  혹시 추가로 확인해야할 부분이 있을까요?   감사합니다.

api 추가 질문입니다. router.get('/search/:hashtag', async (req, res, next) => {   try {     const result = await request(       req, `/posts/hashtag/${encodeURIComponent(req.params.hashtag)}`,// 문자를 UTF-8로 인코딩     );     res.json(result.data);   } catch (error) {     if (error.code) {       console.error(error);       next(error);     }   } }); 이 코드에서 :hashtag는 인코드 되어서 request함수에 넣었습니다. router.get('/posts/hashtag/:title', verifyToken, async (req, res) => {   try {     const hashtag = await Hashtag.findOne({ where: { title: req.params.title } });     if (!hashtag) {       return res.status(404).json({         code: 404,         message: '검색 결과가 없습니다',       });     }     const posts = await hashtag.getPosts();     return res.json({       code: 200,       payload: posts,     });   } catch (error) {     console.error(error);     return res.status(500).json({       code: 500,       message: '서버 에러',     });   } }); request함수는 헤더의 authorization에 토큰을 넣어서 이 라우터에 요청합니다. 그렇다면 이 코드의 :title 속성은 인코드된 문자열이지 않나요? Hashtag모델에 인코드된 문자열이 저장되는 것도 아니던데 왜 인코드된 문자열을 다시 디코드하지 않나요? const posts = await hashtag.getPosts();     return res.json({       code: 200,       payload: posts,   }); 또 Post에 있는 hashtag를 가져와 posts에 넣어서 json형식으로 출력했더니 이런 형태의 데이터가 나왔는데 Post모델에서 조건에 맞는 hashtag를 가져온것은 이해 했습니다. 그러나 PostHashtag테이블과 UserId컬럼은 왜 가져온것인가요? 혹시 관계 메서드 add set remove get에 대해 정확히 어떠한 인과관계가 나타는지 설명해주실수 있나요? 대충 느낌은 오지만 긴가민가 합니다 ㅜㅜ

안녕하세요! 강의 잘 듣고 있습니다. 크리티컬한 질문은 아닌데요! boiler-plate 때 project를 만들었었는데, tdd-app에도 project를 새로 만들었습니다. 강의와 같이 간단한 프로젝트들이라면 프로젝트를 새로 안만들고 안쪽의 dbname만 바꿔서 사용하는 느낌으로 가는건가요? uri에서 dbname을 바꾸는건? 어떤 의도로 사용되는건지 여쭤보고 싶습니다!  

저만 그런건지 모르겠지만 아래 환경에서 jest.fn() is not function 에러가 발생하고 있습니다. 1. Express.JS 사용 중 2. ES6 문법을 사용 중 3.  package.json 에 "type":"module" 옵션 추가 4. 그로 인해 import 구문의 './파일명.js' 로 작성해야함 5.  package.json 의 script 항목의 "test" : "jest" 를 아래로 변경 "node --experimental-vm-modules node_modules/jest/bin/jest.js"    에러 발생 원인은 '.js' 부분 떄문이라고 추측하지만 정확하지 않습니다. 떠힌 Jest NODEModules 기능은 실험적 기능이며, 몇몇 기능이 지원되지 않는 것이라고 추측하고 있습니다.따라서 dev 환경에서는 ES6 를 쓰도록 별도로 셋업하고 ES5 로 빌드 하는 과정이 필요한 것이 아닌가 싶었습니다.git clone https://github.com/unchaptered/express-web my-app 혹은npx degit unchaptered/express-web my-appcd my-appnpm i를 이용해서 프로젝트를 셋업하고 작성하시면 됩니다.커뮤니티에도 올려두었는데 문제 되는 부분 있으면 댓글 부탁드립니다.  ES6 Express Jest Boilerplate Template ES6 익스프레스 보일러플레이트 탬플릿 - 인프런 | 자유주제 (inflearn.com)

안녕하세요 강사님 궁금하게 생겨 문의 드립니다.     다음 사진처럼 항상 파일을 클릭하면 상단 import줄이 저렇게 변하는데요 파일을 다시 닫으면 빨간줄이 사라집니다.   깃허브에 있는 tsconfig.json과 .eslintrc.js는 그대로 복붙했습니다. 제가놓친게있을까요?

안녕하세요 강사님 cats.module.ts 파일에서  import: [MongooseModule.forFeature([{ name: Cat.name, schema: CatSchema }]),이부분에서 빨갛게 해논부분에 왜 Cat.name , name이 붙어있는 이유가 뭔지 알고싶습니다. 저기서 name에 할당한 값으로 Service에서 생성자 주입 받을때? Cat.name 으로 @InjectModel(Cat.name) 하는걸로 보이는데 왜 ".name" 이 붙은건가요?..  

threads.add(new Worker(__filename, { workerData: { start, range: range + ((max - min + 1) % threadCount) } }));   for문에서 threadCount - 1 안 하고 threadCount 까지 반복하면 안 되는 이유가 있는지 궁금합니다. 마지막에 따로 빼면 range가 10000007까지로 되는거 같아서요.

직접 공식문서 찾아드리려 했지만 이분께서 정리를 잘 해주셨습니다. ant design업그레이드 되면서 바뀐 문제입니다.   참고: https://shinye0213.tistory.com/317
