무한스크롤 구현시 <div ref={fetchMoreEl} /> 이부분이 화면스크롤시 제대로 감지가 안되는 건지 useEffect 에서 intersecting 이 계속 false 더군요 제가 해결한 방법은 <div ref={fetchMoreEl} style={{ border: '1px solid white' }}></div> 이렇게 입력해서 정상작동하는 것을 확인했습니다. 비슷한 문제 발생시 참고용~

명령프롬프트 화면의 내용을 지울때 어떤 명령어를 쓰시는것같은데 알려주세요 ㅠ 저는 껐다켰다계속하고있어요 ㅠ

  안녕하세요. 양질의 강의를 제공해주시는 것에 대하여 감사의 말씀 먼저 올립니다...!   이제 막 스프링을 공부하고 있는데 궁금한 점이 생겼습니다. 스프링으로 DB를 연동할때 application.properties에 설정하여 DB연동하는것으로 알고 있습니다. 그런데 만약 n개의 DB에 접속해야할때는 어떤방식으로 해야할까요?   e.g) A회사, B회사 DB에 접속해야하는데 A회사의 DB는 192.168.11.100:3306 이고 B회사의 DB는 192.168.15.101:3306 인 경우 입니다.   감사합니다.

안녕하세요 제로초님.   지금 포트폴리오를 만드는김에 빌더까지 확장해서 만들어 볼까 싶은데 힌트를 찾지 못해서 질문 드립니다.   일단 각 게시판 별로 스킨을 만들어서 DB에 스킨명을 저장할 생각입니다. fs으로 스킨명의 js파일을 찾아 저장할 생각인데 문제는 해당 컴포넌트를 어떻게 import해서 가져와서 뿌려주느냐 입니다.     위 스샷처럼 list에 Basic 이라는 리스트 컴포넌트와 Thumbnail이라는 리스트 컴포넌트 2개를 가지고 있습니다. 예를들어서 notice게시판과 photo게시판 2개의 게시판이 있고, db에 게시판 설정 테이블을 만들고 notice 게시판은 리스트 스킨을 Basic으로 저장하고, photo게시판은 Thumbnail로 저장합니다. notice라는 게시판에서는 Basic 컴포넌트를 , photo라는 게시판에서는 Thumbnail컴포넌트를 불러와 사용하게 하려 하는데   제가 node를 다루기 전엔 php만 다뤄봐서 php에선 그냥 단순히 스킨명을 string으로 가져와서 include로 가져왔으면 됐는데 node에서는 어떻게 하면 따로 불러와서 사용할수있는지 궁급합니다.   혹시나 제가 만들려는 접근방식이 틀렸다면, 검색 키워드좀 부탁드리겠습니다. 감사합니다

  강사님은 엄격모드를 끄고 하시는데 저처럼 엄격모드 켜고 하시는분들은 이런 에러를 만나보셨을꺼라 생각합니다. 솔루션이라고 하긴 좀 애매하지만.. https://segmentfault.com/a/1190000040975322 1. 엄격모드 끄기 2. antd.css 안쓰기 3. 업데이트를 기다리기 오류에 대해서는 무시를 해도 된다고 하지만 찝찝한 기분은 지울수없습니다. 질문글은 아니지만 이러한 현상에 대해서 어떻게 생각 하시는지 의견 부탁드립니다. 예를들어 그냥 엄격모드를 끄고하겠다. 아니면 오류는 이제 무시를 하겠다. 이런느낌입니다. "antd": "^4.17.4", "react": "^17.0.2",

types/index.d.ts에 global로 타입 확장을 해주고 passport에 user.id에 에디터 상으로 오류는 발생하지 않는데. nodemon 실행하면 Property 'id' does not exist on type 'User'. 라고 출력됩니다. 또한 콘솔을 찍으면 해당형식으로 출력되는데 정상인건가요? User {   dataValues: {...}   _previousDataValues: {...} }

안녕하세요, 문제풀이 해주신 리트코드 문제에서는 record date에 interval 1을 써서 셀프 조인을 했는데요. 이때 input 데이터의 record date의 형식이 특정 포맷일때만 interval 1을 쓸 수 있을 것 같은데요.예를 들면 엑셀에서도 특정 셀 값이 '숫자'로 표시된 것과 '날짜'로 표시된 것은 다를 떄가 있듯이요.interval 함수를 쓰기 위해서 input 데이터가 어떤 형식으로 되어있어야 하는지를 설명해주시면 좋을 것 같습니다. 감사합니다.

안녕하세요 3.4 plotly 선 그래프 그리기를 하는데   새롭게 업데이트도 하고 이러저리 해봤는데도 하얀 바탕으로만 나와서 더 이상 강의가 진행이 안되네요 ㅠㅠ   어떻게 하면 좋을까요??

Amazon linux 2로 EB 환경을 구성해놓았습니다. 1. 이해가 잘 안 가는 것이 travis.yml을 이용해서 빌드할 때도 docker-compose.yml을 이용할 때와 같이 AWS_EB에 배포할 때도 같은 docker-compose.yml을 이용한다는 말씀이신가요?   2. 여러개의 EB 인스턴스로 하나의 RDS를 사용할 수도 있나요?

안녕하세요 선생님, 좋은 성탄절 보내셨기를 바랍니다! :)   다름이 아니라, http status code를 모두 200으로 주는 것에 대해 선생님의 의견을 여쭙고자 커뮤니티에 글을 남깁니다.   많은 백엔드 개발자분들이 "http status code는 네트워크 통신코드이기 때문에 통신이 되기만 하면 200으로 내려주는 것이 맞다. 세부적인 api 호출 결과는 따로 주는 것이 맞다."   라는 입장을 가지고 있습니다.   또한 자체적으로 창의력을 발휘하여 0, -1등을 사용하는 회사도 많이 보았습니다.   이에 대해 선생님은 어떻게 생각하시나요?   이런 이슈는 웹프론트로 치면 모든 html element를 div로 만드는 것과 같이, "그렇게 해도 서비스가 돌아가긴 하지만, 웬만하면 그러지 말아라" 정도의 이슈인걸까요?   순수한 궁금증이 들어 문의 남깁니다.

안녕하세요, 김영한님 강의 잘 듣고있습니다! 혹시 from 절에 subquery를 사용하게 되는 경우 JPA에서는 한계가 있다면 View 테이블을 만들어 놓고 Entity class를 생성하여 사용하는건 실무에서 문제가 있을까요? (유지보수 관점에서요!) select * from (select ~~~ from ~~) ~~ 이거를 create view XXX as select ~~~ from ~~ view 를 만들어놓고 select * from XXX; 요렇게요 답변 미리 감사합니다 :)

안녕하세요! 복습을 해보다 보니, print와 type을 뭐라고 불러야할지 모르겠어요. str1 = apple이라고 정의한다면 str1은 변수가 될텐데, 여기서 print(type(str1)) 이라는 구문을 썼을 때 print, type은 뭔지 (함수? 메소드?) 결과로 나오는 <class 'strl'>에서 class는 뭘지 궁금해요.   강의 잘 듣고 있습니다! 쏙쏙 들어오는 강의 감사합니다. 도움 주시는 선배 개발자 분들도 감사합니다~!
