Hey Steven,
thanks a lot for your feedback :) I totally agree with you, securing the database is a crucial topic, especially when your app is (or will be) in production one day.
I'll definitely have a look at it and include it in one of the following parts of this MongoDB series!
Have a nice day :)

You should add the one thing every tutorial neglects: How to lock it down and secure the database. As soon as you do this with a VPS, for app-oriented transactions, your DB collections are going bye-bye (aka "hijacked") within the next six months (if you're lucky.)
