Overview

Very simple function to allow persistence of a reducer's state to local storage. Note that this makes the reducer "impure" since it will have the side effect of persisting its state.

This works only in the browser.

Usage

import {saveState, restoreState} from 'persist-reducer'

const saveConfig = {
    storageKey: 'something unique',
    keysToSave: ['key1', key2']  // optional list of keys to include in saved state
}

const defaultState = restoreState(saveConfig, ...)

const reducer = saveState(saveConfig, function(state, action) {
    // normal reducer stuff
})

Comparison with redux-persist

redux-persist is much more featureful. It also registers at the store level, as opposed to persist-reducer which is applied on a single reducer.
