this is definitely still a problem; JS doesn't guarantee integers larger than 29 bits or something, and Datomic uses 64-bit IDs for everything.

so generally I'd say that whatever API you're using to sync Datomic data to DataScript should convert IDs to strings. it's less obvious what to do with actual data values.

I mean, a :db.type/long field has the same problem. your data may not be too big though.

Thank you Braden, I’ll use the string strategy then.

I’ve done something similar before, we added a unique attribute :ent/uid (uuid’s or some other uniquely generated string) to every entity and dropped the db/ids when syncing
