1. serializeUser
: 사용자 정보 객체를 세션에 아이디(객체)로 저장
passport.serializeUser((user, done) => {
//done(null, user); // id만 세션에 저장
done(null, user; // user 객체 세션에 저장
});
2. deserializeUser
: 세션에 저장한 아이디(객체)를 통해서 사용자 정보 객체를 불러옴
passport.deserializeUser((user, done) => {
console.log('deserializeUser() 호출!', user);
done(null, user);
});
3. passport.session() 미들웨어가 메소드를 호출
조회한 정보를 req.user 저장

7. socket.io 모듈
: 웹소켓을 이용하면 클라이언트에 실시간으로 데이터를 전송할 수 있다.
socket을 구현하는 것으로 WebSocket 개발을 쉽게 하기 위한 방법이다.
클라이언트에서 EventListener로 새로운 정보를 받아 데이터를 업데이트한다.
8. socket.io으로 할 수 있는 것
① 실시간 데이터 처리
② 메세징 서비스
③ 바이너리 스트리밍, 문서 공동작업 등
9. 여러 개의 클라이언트를 서버로 접속하게 하기 위한 방법
① cors 모듈(socket.io 적용 안함, ajax로 변환)
② package.json에 proxy 설정
10. socket.io 서버 추가(아까 작업한 거 config, database, public, routes, views, package.json 가져오기)
