Can I get the previous doc data in the Update event?

[mingz-unity]

Hi coming from collection-hook and wonder if the same feature is available here:

When I am in one of those collection update events, can I have access to the previous value so I can do some change handling? I inspected the runtime class of "e" and it only contains the changed value not the original.

Is there anywhere I can get that?
Thanks

@mingz-unity in the newest Astronomy version you can access the old document in the beforeUpdate event in the following way:

beforeUpdate(e) {
  e.oldDoc; // Do something with the previous document state
}

Cool cool that's great. Yes I dig into the source code and found out. That's great thanks Luke.

oldDoc is not available on the server? Is it by design? @lukejagodzinski

@s7dhansh thanks for letting me know that it doesn't work on the server. I've fixed it in jagi:astronomy@2.7.3

@lukejagodzinski the new version has made the updates take a lot of time. Can you kindly check that? Can we have some way to make it faster when we have disabledEvents for an update?

Ok, I will check that this week and try to improve performance

@lukejagodzinski sorry you can ignore that last comment. It was caused by something else locally.
