nodejs mongodb object id to string
Solution 1:
Try this:
user._id.toString()
A MongoDB ObjectId is a 12-byte UUID can be used as a HEX string representation with 24 chars in length. You need to convert it to string to show it in console using console.log.
So, you have to do this:
console.log(user._id.toString());
Solution 2:
Take the underscore out and try again:
console.log(user.id)
Also, the value returned from id is already a string, as you can see here.
