 Also you can create special guard component as shown in [this example](https://svelte.dev/repl/5673ff403af14411b0cd1785be3d996f).

+### Scroll on top
+
+Tinro doesn't control scroll of the your app. Sometimes you need to scroll on top of the page when navigating between pages. Just add the `router` store subscription in your root component(ex. `App.svelte`). Using this way you can run any actions(not only a scroll), every time when `URL` changes.
+
+```javascript
+import {router} from `tinro`;
+router.subscribe( _ => window.scrollTo(0, 0));
+```
