Share LocalStorage/SessionStorage between different domains in (angular 6)

Question

in Angular 6, when I stored the data in local storage (localhost:4200) but when we can run a subdomain like(abc.localhost:4200) that time data removed in local storage please help me out this problem

Answer 1

You can use Cross Storage or Cross DomainStorage npms

Answer 2

In short. No.

This is the definition of localStorage specification. As Mozilla said;

The read-only localStorage property allows you to access a Storage object for the Document's origin;

and there are some examples of what is Document origin.

Answer 3

Data stored to domain.com can not be accessed from sub.domain.com as per the standards. So you cant access local storage of localhost:4200 from abc.localhost:4200 no matter what you do. But to overcome this you may use solutions suggested by these posts,
