Advanced

You can access the Storage, StorageArea and Emitter objects:

// If you need another storage - { local, sync, managed, onChanged }
const Storage = require('mem-storage-area/Storage')
const storage = new Storage()

// If you need an emitter
const Emitter = require('mem-storage-area/Emitter')
const onChanged = new Emitter()
// onChanged.addListener, onChanged.removeListener, onChanged.hasListener etc.
// To emit, call onChanged(arg0, arg1...)

// If you need a storage area (with optional emitter)
const StorageArea = require('mem-storage-area/StorageArea')
const area = new StorageArea({ name: 'myArea', onChanged, readOnly: false })
