Guide on displaying the login component as the initial view upon app initialization instead of the app component in Angular 5

Just starting out with Angular 5 and looking to implement a login page as the initial screen of my app.

Currently, my appComponent displays a toolbar and side navigation bar. However, I want to first show a login screen upon app load. Once the user successfully logs in, they should be redirected to the Home page where different components can be loaded based on menu selection.

If I set my appComponent as the login component, I lose the ability to load different components on the Home page based on user selection from the menu.

Here is a snippet of my app.component.html:

<mat-sidenav-container fullscreen>
    <!-- Side Nav here -->
</mat-sidenav-container>

When running the application, currently the default landing page is the Home page. My goal is to display a full-screen login page initially, rather than automatically navigating to the Home page.

const routings: Routes = [
    {path:'',redirectTo:'/login',pathMatch:'full'},
    {path:'home',component:HomeComponent},
    {path:'account',component:AccountComponent},
    {path:'settings',component:SettingsComponent},
    {path:'**',redirectTo:'/login',pathMatch:'full'},
];

Instead of redirecting to app-root when the URL is blank or invalid, I aim to direct users to the login page. Any help or suggestions on how to achieve this would be greatly appreciated!

To enhance the security of your application, it is recommended to utilize a guard as a more effective solution in your scenario. The primary goal is to restrict any unauthorized access to your AppComponent.

Develop a guard that verifies the user's authentication status and apply it to your AppComponent. Within the guard, if the user is not authenticated, redirect them to the LoginComponent.

import { Injectable } from '@angular/core';
import { CanActivate, Router } from '@angular/router';

@Injectable()
export class LoginGuard implements CanActivate {
    constructor(private router: Router) {}

    canActivate() {
        // Add authentication check logic here
    }
}

Implement your authentication verification logic within the canActivate function.
