How do you deal with serializing properties "by reference"? E.g., if 3 objects reference object "Foo", then Foo is serialized once instead of being duplicated in the json 3 times?
It depends. I don’t tend to end up with deep object graphs that need to be saved/ reloaded.
It might be that we serialize foo and foo has a list of references to its 3 children. The “parent” reference from the child back to foo is marked as do not serialize; an “after rehydration” function on foo could then set the value each child’s parent reference.
But more often — say baz bar and bam reference foo — the speed at which baz changes is different to the speed at which foo changes. The reference to foo from Baz is marked do not serialize. Baz also has a property indicating the ID of Baz. (For IStashy<K> - K is the type used for the keys, the IDs; it might be a string or an int or a guid, I tend to use string. All objects in the system have the same kind of ID, and it is unique per type.)
Generally if cyclic data structures are possible then some part of the cycle will be marked as no serializable and I’ll keep a key reference adjacent to it.
Situations that triggers huge cascading saves — they’re kind of an anti pattern for how I work. If one little change changes everything then perhaps it can be calculated on the fly from a pure function, not persisted at all— or perhaps there’s over-coupling etc.
