Vue plugin for work with local storage, session storage and memory storage from Vue context
jsFiddle Example
Install
CDN
Recommended: https://unpkg.com/vue-ls, which will reflect the latest version as soon as it is published to npm. You can also browse the source of the npm package at https://unpkg.com/vue-ls/
Also available on jsDelivr or cdnjs, but these two services take some time to sync so the latest release may not be available yet.
NPM
npm install vue-ls --save
Yarn
yarn add vue-ls
Bower
bower install vue-ls --save
Development Setup
# install dependencies npm install # build dist files npm run build
Usage
Vue storage API.
import Storage from 'vue-ls'; const options = { namespace: 'vuejs__', // key prefix name: 'ls', // name variable Vue.[ls] or this.[$ls], storage: 'local', // storage name session, local, memory }; Vue.use(Storage, options); //or //Vue.use(Storage); new Vue({ el: '#app', mounted: function() { Vue.ls.set('foo', 'boo'); //Set expire for item Vue.ls.set('foo', 'boo', 60 * 60 * 1000); //expiry 1 hour Vue.ls.get('foo'); Vue.ls.get('boo', 10); //if not set boo returned default 10 let callback = (val, oldVal, uri) => { console.log('localStorage change', val); } Vue.ls.on('foo', callback) //watch change foo key and triggered callback Vue.ls.off('foo', callback) //unwatch Vue.ls.remove('foo'); } });
Use in js file
// localStore.js import Storage from 'vue-ls'; const options = { namespace: 'vuejs__', // key prefix name: 'ls', // name variable Vue.[ls] or this.[$ls], storage: 'local', // storage name session, local, memory }; const { ls } = Storage.useStorage(options) export default ls // somefile.js import ls from 'localStore.js'; ls.set('foo', 'boo'); ls.get('foo');

Testing Supported By
Note
Some browsers don't support the storage event, and most of the browsers that do support it will only call it when the storage is changed by a different window. So, open your page up in two windows. Click the links in one window and you will probably see the event in the other.
The assumption is that your page will already know all interactions with localStorage in its own window and only needs notification when a different window changes things. This, of course, is a foolish assumption. But.
