@Directive configuration applies to components as well
The provided classes are added to the element when the routerLink becomes the current active route.
class CanActivateGuard implements CanActivate {
canActivate(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean>|Promise<boolean>|boolean { ... }
}
{ path: ..., canActivate: [CanActivateGuard] }An interface for defining a class that the router should call first to determine if it should activate this component. Should return a boolean or an Observable/Promise that resolves to a boolean.
+class CanActivateGuard implements CanActivate {
canActivate(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean|UrlTree>|Promise<boolean|UrlTree>|boolean|UrlTree { ... }
}
{ path: ..., canActivate: [CanActivateGuard] }An interface for defining a class that the router should call first to determine if it should activate this component. Should return a boolean|UrlTree or an Observable/Promise that resolves to a boolean|UrlTree.
class CanDeactivateGuard implements CanDeactivate<T> {
canDeactivate(
component: T,
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean>|Promise<boolean>|boolean { ... }
}
{ path: ..., canDeactivate: [CanDeactivateGuard] }An interface for defining a class that the router should call first to determine if it should deactivate this component after a navigation. Should return a boolean or an Observable/Promise that resolves to a boolean.
+class CanDeactivateGuard implements CanDeactivate<T> {
canDeactivate(
component: T,
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean|UrlTree>|Promise<boolean|UrlTree>|boolean|UrlTree { ... }
}
{ path: ..., canDeactivate: [CanDeactivateGuard] }An interface for defining a class that the router should call first to determine if it should deactivate this component after a navigation. Should return a boolean|UrlTree or an Observable/Promise that resolves to a boolean|UrlTree.
class CanActivateChildGuard implements CanActivateChild {
canActivateChild(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean>|Promise<boolean>|boolean { ... }
}
{ path: ..., canActivateChild: [CanActivateGuard],
children: ... }An interface for defining a class that the router should call first to determine if it should activate the child route. Should return a boolean or an Observable/Promise that resolves to a boolean.
+class CanActivateChildGuard implements CanActivateChild {
canActivateChild(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean|UrlTree>|Promise<boolean|UrlTree>|boolean|UrlTree { ... }
}
{ path: ..., canActivateChild: [CanActivateGuard],
children: ... }An interface for defining a class that the router should call first to determine if it should activate the child route. Should return a boolean|UrlTree or an Observable/Promise that resolves to a boolean|UrlTree.
class ResolveGuard implements Resolve<T> {
resolve(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<any>|Promise<any>|any { ... }
}
{ path: ..., resolve: [ResolveGuard] }An interface for defining a class that the router should call first to resolve route data before rendering the route. Should return a value or an Observable/Promise that resolves to a value.
class CanLoadGuard implements CanLoad {
canLoad(
route: Route
): Observable<boolean>|Promise<boolean>|boolean { ... }
}
{ path: ..., canLoad: [CanLoadGuard], loadChildren: ... }An interface for defining a class that the router should call first to check if the lazy loaded module should be loaded. Should return a boolean or an Observable/Promise that resolves to a boolean.
+class CanLoadGuard implements CanLoad {
canLoad(
route: Route
): Observable<boolean|UrlTree>|Promise<boolean|UrlTree>|boolean|UrlTree { ... }
}
{ path: ..., canLoad: [CanLoadGuard], loadChildren: ... }An interface for defining a class that the router should call first to check if the lazy loaded module should be loaded. Should return a boolean|UrlTree or an Observable/Promise that resolves to a boolean|UrlTree.
