Histore

Histore [his·to·ry]: a 200b key-value store backed by navigation state.

Does the fact that sessionStorage/localStorage is shared across tabs have you down?

Don't worry, here's a strange but widely supported way to store 640kb of object data in a page's navigation state.

Usage

import histore from 'histore'

let storage = histore()

storage.set('foo', 'bar')
storage.get('foo')  // 'bar'

storage.set('obj', { any: 'object' })
storage.get('obj').any  // 'object'

Interestingly, due to the way history.replaceState works, storing objects will implicitly clone them using the Structured Clone algorithm.
