Yassin Mo I am create a project with angular 17.. after create application app.module.ts file is not available. I have a seprate module for login. i have a seprate component for navbar. In the login component i create a property name login. Click on Login Button i have store all data with authenticationService. After storing login data in authentication service i have create a observable like this loggedIn= new BehaviorSubject<boolean>(false);
get isLoggedIn() { return this.loggedIn.asObservable();//push Interface } in login method send
this.loggedIn.next(true); and this observale in the app.component.ts
this.isLoggedIn$ = this.authenticationService.loggedIn; but when i am login this.isLoggedIn$ is not working if i am refresh the page its working fine.
