StateX maintains it's own state. However you can subscribe to state changes and update state based on your own global state using the following.

import { State } from 'statex'
import Immutable from 'statex/dist/core/immutable'

// subscribe to state changes
State.subscribe((state) => console.log('changed state', state))

// update state
State.next(Immutable.from(newState))
