MongoParseError: options usecreateindex, usefindandmodify are not supported

[문제사항]

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

몽구스 패키지를 설치하고 연결하고 프로젝트를 실행시켜봤는데 

에러로그를 출력하면서 프로젝트 코드를 실행됩니다.

> start
> node app.js

Example app listening on port 3000

[해결방법]

package.json에서 mongoose의  버젼이 6.0 이상이라면

mongoose는

useNewUrlParser: true

useUnifiedTopology: true

useCreateIndex: true

useFindAndModify: false

로 기억하고 실행하기 때문에 더이상 지원하지 않기때문에

MongoParseError: options usecreateindex, usefindandmodify are not supported 라는 에러문구가 뜹니다.

 

문제해결방법은 두번째 객체 인자를 지우면 됩니다.

const PASSWORD = "몽고디비 아틀라스에서 등록한 클러스터의 패스워드 입력하면됩니다 ^^"
mongoose.connect(`mongodb+srv://root:${PASSWORD}@cluster0.4019o.mongodb.net/?retryWrites=true&w=majority`)
