Error

The Angular 2 router will only update the target component with the url and params. Each component is initialized only when it comes into view. If it already visible when the url changes, it will not be updated by the router. For google, angular 2 components not updating when url changes.

If you’re used to using Angular 1 with ui-router ($state and $stateParams services), using Angular 2 can be frustrating. Instead of using ui-router, we will try to stick with the barebones Angular 2 setup. Angular 2 has its own routing component that has been a huge improvement over the Angular 1 routing component. However, it does not follow the same design as ui-router, which was much easier in my opinion.
