What should I use other than .findAndModify?

Question

I have the following code:

var roomDoc = Rooms.findAndModify({
  query: {name: roomName},
  update: {$setOnInsert: {unixTimestamp: unixTimestampSeconds()}},
  new: true,
  upsert: true
});

After getting an error that .findAndModify is undefined, I realized, Meteor doesn't implement .findAndModify.

Is there a Meteor way to achieve similar functionality by using different queries?

Answer 1

However the answer above explains this specific case, in many other cases it is supposed that findAndModify is an atomic operation that could be used for example to generate unique IDs:

It seems that Meteor won't implement a wrapper of findAndModify as a corresponding ticket is already closed, however the community proposed several solutions that already work on both server and client sides:
