아래 3가지 에러가 발생을 할 것이고,
|
1. (node:18886) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect. 2. TypeError: db.collection is not a function
3. (node:21860) DeprecationWarning: collection.insert is deprecated. Use insertOne, insertMany or bulkWrite instead.

userNewUrlParser, client.db, inertMany 변경으로 해결 하였다.
