ISerializableValue Interface

Packages > @fluidframework/map > ISerializableValue

The _ready-for-serialization_ format of values contained in DDS contents. This allows us to use ISerializableValue.type to understand whether they’re storing a Plain JS object, a SharedObject, or a value type. Note that the in-memory equivalent of ISerializableValue is ILocalValue (similarly holding a type, but with the _in-memory representation_ of the value instead). An ISerializableValue is what gets passed to JSON.stringify and comes out of JSON.parse. This format is used both for snapshots (loadCore/populate) and ops (set). If type is Plain, it must be a plain JS object that can survive a JSON.stringify/parse. E.g. a URL object will just get stringified to a URL string and not rehydrate as a URL object on the other side. It may contain members that are ISerializedHandle (the serialized form of a handle). If type is a value type then it must be amongst the types registered via registerValueType or we won’t know how to serialize/deserialize it (we rely on its factory via .load() and .store()). Its value will be type-dependent. If type is Shared, then the in-memory value will just be a reference to the SharedObject. Its value will be a channel ID. This type is legacy and deprecated.
