안녕하세요 강사님. 강의 보며 많이 배우고 있습니다. 강의 내용대로 쭉 따라가며 진행하고 있는데 회원가입 부분에서 회원가입 제출 누르면 홈으로 리다이렉트가 안되고 403에러와 화이트라벨 페이지로 이동하게 됩니다. create 메서드에 로그를 찍어도 안찍히는걸 보니 해당 post 매핑이 잘못되었나 하여 준비해주신 자료에 있는 소스를 복사해 똑같이 붙여넣기해도 마찬가지네요... 혹시 원인이 무엇일까요..ㅠㅠ

유니티3D를 사용한 VR 제작 기초.
안녕하세요. VR 개발에 관심있는 학생입니다. 학교 졸업 프로젝트를 위해 강의를 듣다 보니 생각보다 VR개발에 흥미가 생겨 오큘러스 장비를 구매하려고 합니다. 다만, 걱정인 것은 학교에 구비된 VR 기기가 오큘러스 리프트라는 점입니다. 오큘러스 리프트로 윈도우 기반 프로그램을 개발하면서 오큘러스 퀘스트를 프로그램 개발 확인용으로 사용할 수 있을지 궁금합니다. 답변 기다리겠습니다 좋은 강의 잘 듣고 있습니다 :)

제가 이렇게 해준 이유는 우선 비밀번호에 조건을 달아주었는데요. 비밀번호 값을 입력했을때 조건에 맞지않으면 에러메시지를 띄워주는데 onChange에서 에러를 감지해주었을경우 비밀번호를 초기화해도 에러메시지는 남아있더라구요. 반면에 useEffect에서 처리해주었을경우엔 password값이 업데이트 될때마다 상태가 바뀌어서 에러메시지가 사라졌는데 useCallback도 원레 두번째 deps가 바뀌면 함수자체를 다시 실행해줘서 에러메시지가 사라져야하지 않나요?? 제가 놓친 부분이 어떤부분인지, 현재 작성한 코드는 알맞게 작성한건지가 궁금합니다.

Vue.js 완벽 가이드 - 실습과 리팩토링으로 배우는 실전 개념
안녕하세요. 강의 잘 듣고 있습니다. 차트 import관련해서 질문드립니다. 강의에서는 import Chart from ' chart.js ' 로 하셨는데 그렇게 하게 되면 다음과 같은 에러가 발생합니다 그래서 import Chart from ' chart.js ' 의 chart.js 를 클릭해서 들어가보니 index.esm.d.ts 파일이 열리더라구요. 그래서 import Chart from ' chart.js/dist/chart.js ' 로 수정하니까 정상 작동하긴 하는데 제가 chart.js를 잘못 설치 한건가요? 아니면 매번 저렇게 상세하게 적고 사용해야 하는건가요?? 감사합니다.

선생님, 프론트앤드 과정까지 잘 들었습니다. 그런데 백앤드로 들어가면서 외계어를 듣고 있는 듯한 생각이 드는데요. 이게 정상적으로 따라 갈 수 있는 부분인지 의문이 들면서 맨붕이 왔습니다. 당연한 걸까요? 프론트앤드는 클론을 하면서 쉽게 따라가는데, 백앤드 학습의 경우는 어떤 방법으로 하면 좋을지 문의드립니다. (너무 어려워요 ㅠㅠ)
