Angular 15: Issues with Implementing Nested Route Guards for Lazy Loaded Modules
I've searched everywhere and can't find a clear answer. I'm currently working on an Angular 15 application that has several lazy-loaded modules, and I need to implement route guards that depend on the user role. The problem arises when I try to set up nested route guards for the lazy-loaded modules. I have defined a guard for the main route and another guard for a child route, but I'm encountering unexpected behavior when navigating between routes. Here is a simplified version of my routing configuration: ```typescript const routes: Routes = [ { path: 'main', component: MainComponent, canActivate: [MainGuard], children: [ { path: 'child', component: ChildComponent, canActivate: [ChildGuard] }, ]}, { path: 'lazy', loadChildren: () => import('./lazy/lazy.module').then(m => m.LazyModule) } ]; ``` In my `MainGuard`, I check the user role like this: ```typescript @Injectable({ providedIn: 'root' }) export class MainGuard implements CanActivate { constructor(private authService: AuthService) {} canActivate(): boolean { return this.authService.hasRole('admin'); } } ``` The `ChildGuard` checks for a specific permission: ```typescript @Injectable({ providedIn: 'root' }) export class ChildGuard implements CanActivate { constructor(private permissionService: PermissionService) {} canActivate(): boolean { return this.permissionService.hasPermission('viewChild'); } } ``` When I try to navigate to '/main/child', the `MainGuard` works correctly and allows access if the user is an admin. However, if I try to access '/main/child' directly by entering the URL in the browser (with a non-admin role), I'm still able to access the route even though the `ChildGuard` should block it. I've also checked that the guards are properly returning boolean values and that the user roles are being correctly set in the `AuthService`. I suspect there might be an issue with how Angular handles nested guards for lazy-loaded modules. I've tried moving the guards around, but the behavior remains the same. Any insights or suggestions on how to properly implement nested route guards in this scenario would be greatly appreciated! For context: I'm using Typescript on Ubuntu. Is there a better approach?
