I am developing an eCommerce website using angular 7. Currently I am saving the cart information in localStorage. 

```
localStorage.setItem('cartItems', JSON.stringify(this.items));

```

But i found that saved cart information can be alter/delete from browser console.so i am looking for a more secure option which need to be invisible from the user.

Looking for any suggestion or useful link that can be referred and implemented.

Thanks in advance.
