Function for mapping Vuex states two way

mapStatesTwoWay.vuex.js

import { mapState } from 'vuex'

export default function mapStatesTwoWay (namespace, states, updateCb) {
    const mappedStates = mapState(namespace, states)
    const res = {}
    for (const key in mappedStates) {
        res[key] = {
            set (value) {
                updateCb.call(this, { [key]: value })
            },
            get () {
                return mappedStates[key].call(this)
            }
        }
    }
    return res
}

Sorry for the delay... I'll create a module and a demo as soon as possible... please remind me it it takes too long.
