Difference between reading serialized state

[bennyKY]

Hi, im storing state in the db and planned to read it like this:

const userState = await Users.findOneById(userId).state; // string!

const service = interpret(createMachine({ user: this.user }));

service.start(userState);

Now i noticed that there is an example how to read in from localStorage, here i just changed it to db:

const machine = interpret(createMachine{( user: this.user }));
// storing
machine.onTransition((state, event) => await Users.findOneAndUpdate({ id: this.user.id }, {$set: state}))

// reading:
const stateDefinition = JSON.parse(await Users.findOneById(this.user.id).state) || machine.initialState

const previousState = State.create(stateDefinition);

const resolvedState = myMachine.resolveState(previousState);
const service = interpret(myMachine).start(resolvedState);

What is the difference between these approaches? Both will work?
I mean, obviously i wont have history for example on the deserialized state, but lets assume i dont really need it.

Inspect both state objects; that's where the difference will be (if any). Choose the one that suits your needs.

The service.start(someInitialState) call will internally resolve someInitialState from this.machine.resolveState(State.from(someInitialState)).

Great, thanks!
