Description
If all guards return true, navigation continues. If any guard returns false,
navigation is cancelled. If any guard returns a UrlTree, the current navigation
is cancelled and a new navigation begins to the UrlTree returned from the guard.
The following example implements a canActivate function that checks whether the
current user has permission to activate the requested route.
const canActivateChildExample: CanActivateChildFn =
(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) => {
return inject(PermissionsService).canActivate(inject(UserToken), route.params['id']);
};
bootstrapApplication(App, {
providers: [provideRouter([
{
path: 'team/:id',
component: TeamComponent,
canActivateChild: [canActivateChildExample],
children: [],
},
])]
});
