요구사항 거의 다 작업하셨군요 수고 많으셨어요!! 💯
전체적으로 깔끔하게 잘 작성해주셨고, 약간의 중복 코드 개선을 고민해보시면 좋을 것 같아요!

페이지마다 Header, Footer 가 반복된다면 Layout 컴포넌트를 만들어 분리하는 것도 방법입니다!

보통 요런 에러메세지도 상수로 분리해서 관리하곤 합니다!
코드에 텍스트가 섞여있으면 나중에 수정해야할 때 코드 내에서 찾는 게 번거롭기도 하고,
동일한 텍스트가 여러 케이스에서 사용되는 경우도 있어서요
className={`${styles.input} ${ | ||
errorMessage || externalErrorMessage ? styles.invalid : "" | ||
}`} |

제가 멘토링 때 알려드린 classnames 라이브러리를 요럴 때 쓰시면 편합니다!

내부에 자식 없으면 self closing 으로 많이 써요

타입스크립트는 할당된 값을 참조하여 타입 추론을 하기 때문에 이 경우에는 명시적으로 타입 지정하지 않아도 됩니다!
const [email, setEmail] = useState<string>(""); | |
const [email, setEmail] = useState(""); |
(초기값 ''
을 보고 알아서 타입을 string 으로 유추함)
useEffect(() => { | ||
const accessToken = localStorage.getItem("accessToken"); | ||
if (accessToken) { | ||
router.push("/folder"); | ||
} | ||
}, [router]); |

이것도 여러번 반복되니 커스텀훅으로 분리해도 좋겠네요 !
if (emailStatus) { | ||
setEmailError(emailStatus); | ||
} else { | ||
setEmailError(""); | ||

요렇게도 바꿀 수 있겠군요
if (emailStatus) { | |

} | |
setEmailError(emailStatus || ''); |
useEffect(() => { | ||

const response = await fetch(`${BASE_URL}check-email`, { | ||
method: "POST", | ||

const data = await response.json(); | ||

useEffect 쓰지 않고 input 에 change 이벤트 실행 시마다 확인하는 방법도 있을 것 같아요!
현재 방식 유지하더라도 오늘 배운 debounce 활용해보면 좋을 것 같고요!
