네네 그래서 나중에 오타를 잡기 위해 typescript를 사용하거나, 좋은 IDE의 도움을 받습니다.

찾았습니다. 오타가 있었네요 ㅠㅠ

Context 에서 구조분해 할때는 componet 라고 받고

실제 사용할때는 component라고 했네요 

java 할때는 ide단이나 컴파일 단에서 이러한 오타 다 잡아줬었는데

javascript는 이런부분에서 너무 힘드네요 일일이 다찾아야 하다니 ㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠ

그래도 SI 천지이 java 에서 벗어나야겠네요 ㅠㅠㅠㅠ

강좌너무 잘보고있습니다

getInitialProps is running!!!! 이 로그가

 

NodeBird.getInitialProps = async (context) => {

함수 안에 남긴 로그인데
