CanActivateChildFn

The signature of a function used as a canActivateChild guard on a Route.

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: [], }, ]), ],});
