Hello everyone! I am Samuel and I am a young web developer. Actually I am working in a project to help my family's business.
The system is about access control to a vehicle with QR codes. It is composed by a web application (Angular6), mobile application (Ionic3) and REST API (NodeJS) connected to a noSQL DB (MongoDB).
One of my collections is Reservations and the document is structured as follows:
{
_id: number,
serviceId: number,
datetimePaid: Date,
responsible: Person,
state: string,
tickets: Tickets[],
}
And Tickets is something like:
{
price: number,
passenger: Person,
roundtrip: boolean
}
A reservation could be modified by users with differente roles (with higher or lower privileges) but I need to track whenever an user has modified some field of the document to give the administrator a good way to solve possible problems.
The operations or fields that could be updated are:
- datetimePaid
- responsible (replace it with another Person)
- state
- tickets[i].passenger
- Add or remove elements from the tickets array
I haven't find any native solution provided by MongoDB to it, and I have couple of ideas but I would like to hear your strategies or ways to do it.
Many thanks in advance

To me, it sounds like a Change Stream would be ideal here! Here's the documentation: docs.mongodb.com/manual/changeStre...
MongoDB's official blog has a nice little introduction post with code samples too. :)
