I am skipping through the repo but there is one thing I can’t manage to find

and is the source of my issue. So in DDD imagine you have a domain list with tasks. Using typeorm, i can simply “remove” a task from the list domain, and then convert that domain into an persisted entity to be used by TypeORM. So TypeORM will detect automatically that the object you are trying to save vs the item already stored in DB, there is a discrepancy, since the one you are trying to save has a missing record that the DB did have. In this case, you can tell TypeORM to simply remove (aka delete) those orphan records and take as source of truth what your domain is actually composed of

I hope makes sense 😄

Otherwise, if you don’t have that feature what you would need to do woudl be to load the

list

object from the DB, compare the object from the domain vs the one you just loaded, and all the records of

tasks

not available in the Domain you are trying to save, to actually do a

deleteMany

and delete them manually

mainly is a really convenient way to say, hey my domain is my source of truth and update the DB accordingly
