I’m trying to serialise a model object to local storage (or IndexedDB), however it contains signals.

// An example of the model I'm dealing with
export class ExampleModel {
    canSerialise = "";
    cantSerialise = signal("");
}

// What I'd like to be able to do
let exampleModel = new ExampleModel();
localStorage.setItem("example", JSON.stringify(exampleModel));

However this will not serialise cantSerialise as signals are technically functions. I’d like to avoid manually writing serialisation functions for all models that just have a signal in them.

• Tried simply serialising using JSON.stringify():
  • Desired outcome: '{"canSerialise":"","cantSerialise":X}' where X can be anything as long as it serialises back into the original value as a signal (in this case signal(""))
  • Results (as I feared/expected) in '{"canSerialise":""}'
• Thought about using IndexedDB but it won’t be able to serialise signals either since the structured cloning algorithms has the same limitation of nog serialising functions.
