great decision to use the terminal which has no color highlighting or anything to make it more readable 👍

[MrKrzysztof]

All of your videos have been great so far. Would love to see one on Rest with json using node + react but not complaining lol. Thank you so much!

[hemsblr]

Aiming to be a full stack dev like you !

[therodri]

Excelent video, can you try to do more complex and advance agreggations ?

[groundtouche]

Quick question, why would I ever have Item referenced in sales with its price. The Item price would change eventually.. what do you suggest?

[jaggyjut]

wow a full crash course. Thanks. Could you create a tutorial on how to handle an update across two or more collections using a single query. For example if we have a users and posts collection and if we update the username in the users collections, the username in the posts collection should also get updated.

thank you so much for this video, I was looking for $loopups and how ref relation works and you solved my issue.
but I have a question, can you suggest to me which approach I should need to use for a money wallet
like every user have a wallet, so should I link users with the ref approach or embedded approach??

[mdmohiuddin]

i should have find this video earlier :))

Hello bro, how to create a user-users data relationship on MongoDB? In my example, I have users and articles. I want to be able to give every user permission to add article and list and update all his added articles. How do I connect those?

[frenchmike]

newbie question. I see organizations and projects in mongodb, then of course databases in projects etc. If I create a new web application for instance and I call it "workoutApp", do I create a new project named "workoutApp" and place all my db in my project or do I create and organization named 'workoutApp". in which case would I create a new organization ?? thanks

[kevgits]

Are the same functionalities available in Mongoose?

[juleswinnfield]
