안녕하세요

현재 백엔드 서버는 에러는 안나오는데 경고가 나오는것 같습니다.
그 부분은 몽고 DB 쪽 경고인데

mongoose.connect(config.mongoURI, {
useNewUrlParser: true, useUnifiedTopology: true, useCreateIndex: true, useFindAndModify: false
}).then(() => console.log('MongoDB Connected...'))
.catch(err => console.log(err))

이부분을

mongoose.connect(config.mongoURI)
.then(() => console.log('MongoDB Connected...'))
.catch(err => console.log(err))

이렇게 바꿔주세요 ~

클라이언트 부분은 에러가 난 것같은데 혹시 모듈은 다 설치가 됐나요 ~ ?!

네 교수님 하라하신 대로 client랑 server측 npm install 했는데, localhost:5000 접속 시 cannot get / 에러가 없어지질 않네요 ..ㅜㅜ
