ng-localstorage v2.0.3

Ng-LocalStorage

Installation

npm install --save ng-localstorage

Usage

import { NgLocalStorage } from 'ng-localstorage';   

And inject the service to the constructor:

constructor (private storage: NgLocalStorage) { ...

Lastly, don't forget to declare it into your app.module or in the providers section of your component.

providers: [ NgLocalStorage ]

And you can use all localStorage APIs: set, get, remove, clear.

Store Object

ng-localstorage automatically converts Object input to JSON string and save it.

var userData = { name: 'John Doe', email: 'johndoe@mail.com' };
this.storage.set('user', userData);

Get Object

ng-localstorage allows you to retrieve saved items in Object format, which means you can use a dot-notation approach to access Object properties.

// given that userData Object has been saved in localStorage
this.storage.get('user'); // returns {name: 'John Doe', email: 'johndoe@mail.com'}
this.storage.get('user.name'); // returns 'John Doe'

Clearing localStorage

Same as native localStorage API approach.

this.storage.remove('user'); // removes the item `user` in the localStorage list
this.storage.clear(); // clears localStorage
