Angular 15: Issue with Router Guards not Executing on Nested Route Navigation

angular router guard routing typescript

I've spent hours debugging this and I'm relatively new to this, so bear with me. I'm prototyping a solution and I've been struggling with this for a few days now and could really use some help. I'm working on a project and hit a roadblock. I am experiencing an issue where my Angular Router Guards are not executing when navigating to a nested route. I have set up the guards to protect certain routes based on user authentication, but they only seem to work for the primary routes. For example, when I navigate from `/dashboard` to `/dashboard/settings`, the guard does not trigger, and I am redirected without the expected authentication check. Here is a snippet of my routing module: ```typescript const routes: Routes = [ { path: 'dashboard', component: DashboardComponent, canActivate: [AuthGuard], children: [ { path: 'settings', component: SettingsComponent, canActivate: [AuthGuard] }, { path: 'profile', component: ProfileComponent, canActivate: [AuthGuard] } ] }, { path: 'login', component: LoginComponent } ]; ``` In my `AuthGuard`, I have the following implementation: ```typescript @Injectable({ providedIn: 'root' }) export class AuthGuard implements CanActivate { constructor(private authService: AuthService, private router: Router) {} canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean { const isAuthenticated = this.authService.isLoggedIn(); if (!isAuthenticated) { this.router.navigate(['/login']); return false; } return true; } } ``` I have confirmed that `isLoggedIn()` returns the correct value during the guard check. However, when navigating to `/dashboard/settings`, the `canActivate` method does not seem to execute at all. I tried adding logging statements in the `canActivate` method, but they do not appear in the console when I navigate to the nested route. I've also ensured that there are no other conflicting routes defined that might interfere. It seems like the guard is only working for the top-level route. I have checked the Angular Router documentation, but I couldn't find any mention of special considerations for nested routes and guards. What could be causing this behavior, and how can I ensure that my guard executes for all routes, including nested ones? For context: I'm using Typescript on Linux. What's the best practice here? I'm on CentOS using the latest version of Typescript. I've been using Typescript for about a year now. Any suggestions would be helpful. Has anyone else encountered this? Any suggestions would be helpful.
