I\'m new in nodeJS, started learning by following a trailer on youtube, everything goes well until I added the connect function if mongodb,

Answer 1

first create folder by command line mkdir C:\data\db (This is for database) then run command mongod --port 27018 by one command prompt(administration mode)- you can give name port number as your wish

Answer 2

My case was a little different. After restarting my system, I had not whitelisted my IP address on Mongo while doing local development.

Select Network Access > Add IP Address > Add your current IP Address
