Answer 1

How to make the user state persistent even the page reloads?

as @user184994 Mentioned NGRX state is only held in memory. If you want it to persist between page refreshes Go for LocalStorage or sessionStorage

localStorage and sessionStorage accomplish the exact same thing and have the same API, but with sessionStorage the data is persisted only until the window or tab is closed, while with localStorage the data is persisted until the user manually clears the browser cache or until your web app clears the data.

I would suggest you to go for @ngx-pwa/local-storage Async local storage for Angular

For Angular 5:

npm install @ngx-pwa/local-storage@5

Register it in your RootModule

import { LocalStorageModule } from '@ngx-pwa/local-storage';

@NgModule({
  imports: [
    BrowserModule,
    LocalStorageModule,
    ...
  ]

Inject and use it

import { LocalStorage } from '@ngx-pwa/local-storage';

@Injectable()
export class YourService {

  constructor(protected localStorage: LocalStorage) {}

}

Usage

let user: User = { firstName: 'Henri', lastName: 'Bergson' };

this.localStorage.setItem('user', user).subscribe(() => {});
