+# 08-routing-recap
+
+In this activity, you'll learn
+
+- how to leverage the RouterLink directive to make the most use of Angular Router.
+- how to get paremeters from the dynamic urls
+
+## Run this example
+
+From the command line at the root of the project:
+
+```bash
+ng serve 08-routing-recap
+```
+
+## Instructions
+
+### Define Routes & add `<router-outlet />`
+
+1. In `app.routes.ts`, define a route for `HomeComponent` as the default route.
+
+1. Define routes for `DetailsComponent`, add a URL parameter to the path for `DetailComponent` called `id` -
+
+   ```
+   /details/:id
+   ```
+
+1. In `app.component.ts`, add the `<router-outlet />` to component template.
+
+### Update components
+
+1. In `app.component.ts`, dynamically generate a list of links for products in `productTitles`.
+
+   - Generate a link and use the `routerLink` attribute.
+
+   - Use the index of the `productTitles` element
+
+   _Hint, you can access ` $index`` in the context of the  `@for` [@for documentation](https://angular.dev/api/core/@for)_
+
+1. In, `details.component.ts`, create a property called `productId` of type `number`.
+
+1. In detail component define an `@Input` property called `id` and create `setter` function for it:
+
+   ```typescript
+   @Input() set id(value: number) {
+       this.productId = value;
+   }
+   ```
+
+1. Update the `DetailsComponent` template to reference the product from the product list that at the indeces for `productId`.
+
+1. Save your changes.
+
+1. Confirm that you can now route between products in the browser.
