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');

API
Vue.ls.get(name, def)
Returns value under name
in storage. Internally parses the value from JSON before returning it.
def
: default null, returned if not setname
.
Vue.ls.set(name, value, expire)
Persists value
under name
in storage. Internally converts the value
to JSON.
expire
: default null, life time in millisecondsname
Vue.ls.remove(name)
Removes name
from storage. Returns true
if the property was successfully deleted, and false
otherwise.
Vue.ls.clear()
Clears storage.
Vue.ls.on(name, callback)
Listen for changes persisted against name
on other tabs. Triggers callback
when a change occurs, passing the following arguments.
newValue
: the current value forname
in storage, parsed from the persisted JSONoldValue
: the old value forname
in storage, parsed from the persisted JSONurl
: the url for the tab where the modification came from
Vue.ls.off(name, callback)
Removes a listener previously attached with Vue.ls.on(name, callback)
.

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.
