- Using the package directly was creating a second instance and was never triggering the subscriber
- Passing DomainEvents as a dependency solves this issue
refs https://github.com/TryGhost/Team/issues/1306
- This removes the limitation described in commit ff46449ad6
- The only edge case is that when a publication changes their timezone, it will have maximum 24 hours where the member last_seen_at could be incorrect
refs https://github.com/TryGhost/Ghost/pull/14197
- Moved from updating the last_seen_at value "at most every 24h" to "at most every UTC day".
- It will simplify explaining the following behavior: a publication is set in UTC-10, a user visits at 2pm on Monday and at 1pm on Tuesday, the last_seen_at value is still Monday.
- There is no way to go around the above issue due to the technical constraint of updating the `last_seen_at` value at most once a day.
- This might create database write spikes at midnight UTC
refs https://github.com/TryGhost/Team/issues/1306
- Contains all services that listen on member events
- Only contains the last-seen-at-updater service for now
- Listens for `MemberViewEvent` events to update the `member.last_seen_at` timestamp
- Updates after 24hours of the last timestamp to avoid too many writes
- Also updates when the value is NULL
- This is using the existing `last_seen_at` value to avoid an SQL query when no writes are required
