 # Configuration
+
+The configuration of routes in an Angular application involves defining route mappings in an array and providing these routes to the Angular router.
+
+### Example routes:
+```typescript
+const appRoutes: Routes = [
+  { path: 'custom-path', component: CustomComponet },
+  { path: 'custom-path/:id', component: CustomDetailComponet, data: { title: 'Details component' } },
+  { path: '', redirectTo: '/heroes', pathMatch: 'full'},
+  { path: '**', component: PageNotFoundComponent }
+];
+```
+
+- `'custom-path'`: defining a new url route.
+- `'custom-path/:id'` defining _**id**_ parameter.
+- `''` (empty path): instantiate a component without the need for defining a new url route.
+- `'**'`: for undefined paths.
+- The `data` property in the second route is a place to store arbitrary data associated with this specific route.

 The Angular Router raises events when it navigates from one route to another route. It raises several events such as `NavigationStart`, `NavigationEnd`, `NavigationCancel`, `NavigationError`, `ResolveStart`, etc. You can listen to these events and find out when the state of the route changes. Some of the useful events are route change start (NavigationStart) and route change end (NavigationEnd).
