Included example usage in the
ng-sampleforrouter-outlet-test.ts.Implements the
exportAsfeature for thensRouterLinkActivedirective. Taken from Angular's repository, this allows you to dynamically access theisActivestate of the directive to do additional logic outside of just binding classes.Also includes optimizations to the update cycle, to prevent unnecessary DOM manipulations as called out here: https://github.com/angular/angular/blob/master/packages/router/src/directives/router_link_active.ts#L124
