Here I am getting userid from localstorage when user is Authenticated or logged in but that user id is getting as soon as I get logged in even I visit one page to another still not getting but when I reload the page then getting.

What might cause of this issue?

I have logo in header component, in that logo I have given router link and passed parameter as userid, that router only will work when user is logged in, if user is logged out then I have created ng if method that time loggedin logo won't display and won't work. will display other logo.

But when the issue is I need to reload page, without reload page it is not getting

This is header.html code

<a class="navbar-brand" routerLink="" *ngIf="!this.authService.isAuthenticated()">
  <img src="assets/img/logo.png" alt="WAZ_logo">
</a>
<a class="navbar-brand" routerLink="/user-survey/{{Userid}}/{{name}}" *ngIf="this.authService.isAuthenticated()">
  <img src="assets/img/waz_home.png" alt="WAZ_logo">
</a>

this is header.ts

ngOnInit() {
  debugger;
  this.Userid = localStorage.getItem('user_id');
  this.name = localStorage.getItem('user.name');
}

I want to get userid as soon as user get logged in.

I recommend you have a service that handles logging in and which you can query (instead of localStorage) about the info you need.

BUT

You could do it if you refactor your code as follows:

ngOnInit() {
  // empty
}

get Userid() {
   return localStorage.getItem('user_id');
}

get name() {
   return localStorage.getItem('user.name');
}

Your header.html doesn't need any changes.

The localStorage stores strings not objects. You will have to stringify the object and parse it out. Something like this

localStorage.setItem('user', JSON.stringify(user));
let user = JSON.parse(localStorage.getItem('user'));
console.log(user.name);

You also may want to use a service to shared the data between the header component and the login component.
