feat: Add $ifNotExists tot $set operator #85

Closed onhate closed 3 years ago

onhate commented 3 years ago

Allow to set a value only if it does not exists on the record, a good use case is on upsert and setting a createdAt property

{ $set:  { createdAt: { $ifNotExists: date() } } }

extra: allow undefined/null where clause (to be ignored)
