Usage

Vue2 storage API.

import Storage from 'vue-lsp';

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');
    }
});

Vue3 storage API.

// main.js
import Storage from 'vue-lsp';
import App from './App.vue'
const app = createApp(App)

app.use(Storage, {
    namespace: 'vuejs__', // key prefix
    name: 'ls', // name variable [ls] or [$ls],
    storage: 'local', // storage name session, local, memory
  }
)

// in page.vue
import { getCurrentInstance } from 'vue'
export default {
  components: {},
  setup() {
    const instance = getCurrentInstance()
    const { ls } = instance.appContext.config.globalProperties
    ls.set('foo', 'boo');
    // Set expire for item
    ls.set('foo', 'boo', 60 * 60 * 1000); //expiry 1 hour
    ls.get('foo');
    ls.get('boo', 10); //if not set boo returned default 10
    
    let callback = (val, oldVal, uri) => {
      console.log('localStorage change', val);
    } 
    
    ls.on('foo', callback) //watch change foo key and triggered callback
    ls.off('foo', callback) //unwatch
    
    ls.remove('foo');
    return {}
  },
}

// in js
import { ls } from 'vue-lsp'

ls.set('foo', 'boo');
// Set expire for item
ls.set('foo', 'boo', 60 * 60 * 1000); //expiry 1 hour
ls.get('foo');
ls.get('boo', 10); //if not set boo returned default 10

let callback = (val, oldVal, uri) => {
  console.log('localStorage change', val);
} 

ls.on('foo', callback) //watch change foo key and triggered callback
ls.off('foo', callback) //unwatch

ls.remove('foo');

API

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 set name.

ls.set(name, value, expire)

Persists value under name in storage. Internally converts the value to JSON.

• expire: default null, life time in milliseconds name

ls.remove(name)

Removes name from storage. Returns true if the property was successfully deleted, and false otherwise.

ls.clear()

Clears storage.

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 for name in storage, parsed from the persisted JSON
• oldValue: the old value for name in storage, parsed from the persisted JSON
• url: the url for the tab where the modification came from

ls.off(name, callback)

Removes a listener previously attached with ls.on(name, callback).
