just-storage

Just localStorage with a memory fallback.

A barebones localStorage module that checks for not only the existance of localStorage, but also checks that localStorage is enabled in the current session. Falls back to memory storage if localStorage isn't supported.

This implementation works in cases like Safari private browsing, where every call to localStorage throws a quota exceeded error.

Also does simple JSON stringify/parse for you.

Install

$ npm install --save just-storage

Usage

var storage = require('just-storage')
 
storage.set('key', { some: 'value' }) // ==> saves and returns { some: 'value' }
storage('key') // ==> { some: 'value' }
 
var tokenStorage = storage.forKey('myJwt')
tokenStorage() // ==> returns current value of 'myJwt'
tokenStorage.set('19dk2924ksdf') // ==> saves new value to 'myJwt'
