IE9 doesn't support localStorage for file:// URLs.
This is a problem if you're writing an HTML Application
(HTA) in IE9 mode and were expecting to use localStorage to persist some data.
This is a simple implementation of just the functions in the localStorage
API which stringifies a storage object to JSON and writes it to a
.hta-localstorage file in your user profile directory on every change.
getItem(key)setItem(key, value)removeItem(key)clear()
npm install hta-localstorage
