 *
 * ```html
 * <router-outlet></router-outlet>
 * <router-outlet name='left'></router-outlet>
 * <router-outlet name='right'></router-outlet>
 * ```
 *
 * Named outlets can be the targets of secondary routes.
 * The `Route` object for a secondary route has an `outlet` property to identify the target outlet:
 *
 * `{path: <base-path>, component: <component>, outlet: <target_outlet_name>}`
 *
 * Using named outlets and secondary routes, you can target multiple outlets in
 * the same `RouterLink` directive.
 *
 * The router keeps track of separate branches in a navigation tree for each named outlet and
 * generates a representation of that tree in the URL.
 * The URL for a secondary route uses the following syntax to specify both the primary and secondary
 * routes at the same time:
 *
 * `http://base-path/primary-route-path(outlet-name:route-path)`
 *
 * A router outlet emits an activate event when a new component is instantiated,
 * deactivate event when a component is destroyed.
 * An attached event emits when the `RouteReuseStrategy` instructs the outlet to reattach the
 * subtree, and the detached event emits when the `RouteReuseStrategy` instructs the outlet to
 * detach the subtree.

 * <router-outlet

 *
 * Supports static, parameterized, redirect, and wildcard routes, as well as
 * custom route data and resolve methods.
 *
 * For detailed usage information, see the [Routing Guide](guide/routing/common-router-tasks).
 *
 * @usageNotes
 *
 * ### Simple Configuration
 *
 * The following route specifies that when navigating to, for example,
 * `/team/11/user/bob`, the router creates the 'Team' component
 * with the 'User' child component in it.
 *
 * ```ts
 * [{
 *   path: 'team/:id',
 *  component: Team,
 *   children: [{
 *     path: 'user/:name',
 *     component: User
 *   }]
 * }]
 * ```
 *
 * ### Multiple Outlets
 *
 * The following route creates sibling components with multiple outlets.
 * When navigating to `/team/11(aux:chat/jim)`, the router creates the 'Team' component next to
 * the 'Chat' component. The 'Chat' component is placed into the 'aux' outlet.
 *
 * ```ts
 * [{
 *   path: 'team/:id',
 *   component: Team
 * }, {
 *   path: 'chat/:user',
 *   component: Chat
 *   outlet: 'aux'
 * }]
 * ```
 *
 * ### Wild Cards
 *
 * The following route uses wild-card notation to specify a component
 * that is always instantiated regardless of where you navigate to.
 *
 * ```ts
 * [{
 *   path: '**',
 *   component: WildcardComponent
 * }]
 * ```
 *
 * ### Redirects
 *
 * The following route uses the `redirectTo` property to ignore a segment of
 * a given URL when looking for a child path.
 *
 * When navigating to '/team/11/legacy/user/jim', the router changes the URL segment
 * '/team/11/legacy/user/jim' to '/team/11/user/jim', and then instantiates
 * the Team component with the User child component in it.
 *
 * ```ts
 * [{
 *   path: 'team/:id',
 *   component: Team,
 *   children: [{
 *     path: 'legacy/user/:name',
 *     redirectTo: 'user/:name'
 *   }, {
 *     path: 'user/:name',
 *     component: User
 *   }]
 * }]
 * ```
 *
 * The redirect path can be relative, as shown in this example, or absolute.
 * If we change the `redirectTo` value in the example to the absolute URL segment '/user/:name',
 * the result URL is also absolute, '/user/jim'.

 * ### Empty Path
 *
 * Empty-path route configurations can be used to instantiate components that do not 'consume'
 * any URL segments.
 *
 * In the following configuration, when navigating to
 * `/team/11`, the router instantiates the 'AllUsers' component.
 *
 * ```ts
 * [{
 *   path: 'team/:id',
 *   component: Team,
 *   children: [{
 *     path: '',
 *     component: AllUsers
 *   }, {
 *     path: 'user/:name',
 *     component: User
 *   }]
 * }]
 * ```
 *
 * Empty-path routes can have children. In the following example, when navigating
 * to `/team/11/user/jim`, the router instantiates the wrapper component with
 * the user component in it.
 *
 * Note that an empty path route inherits its parent's parameters and data.
 *
 * ```ts
 * [{
 *   path: 'team/:id',
 *   component: Team,
 *   children: [{
 *     path: '',
 *     component: WrapperCmp,
 *     children: [{
 *       path: 'user/:name',
 *       component: User
 *     }]
 *   }]
 * }]
 * ```
 *
 * ### Matching Strategy
 *
 * The default path-match strategy is 'prefix', which means that the router
 * checks URL elements from the left to see if the URL matches a specified path.
 * For example, '/team/11/user' matches 'team/:id'.
 *
 * ```ts
 * [{
 *   path: '',
 *   pathMatch: 'prefix', //default
 *   redirectTo: 'main'
 * }, {
 *   path: 'main',
 *   component: Main
 * }]
 * ```
 *
 * You can specify the path-match strategy 'full' to make sure that the path
 * covers the whole unconsumed URL. It is important to do this when redirecting
 * empty-path routes. Otherwise, because an empty path is a prefix of any URL,
 * the router would apply the redirect even when navigating to the redirect destination,
 * creating an endless loop.
 *
 * In the following example, supplying the 'full' `pathMatch` strategy ensures
 * that the router applies the redirect if and only if navigating to '/'.
 *
 * ```ts
 * [{
 *   path: '',
 *   pathMatch: 'full',
 *   redirectTo: 'main'
 * }, {
 *   path: 'main',
 *   component: Main
 * }]
 * ```
 *
 * ### Componentless Routes
 *
 * You can share parameters between sibling components.
 * For example, suppose that two sibling components should go next to each other,
 * and both of them require an ID parameter. You can accomplish this using a route
 * that does not specify a component at the top level.
 *
 * In the following example, 'MainChild' and 'AuxChild' are siblings.
 * When navigating to 'parent/10/(a//aux:b)', the route instantiates
 * the main child and aux child components next to each other.
 * For this to work, the application component must have the primary and aux outlets defined.
 *
 * ```ts
 * [{
 *    path: 'parent/:id',
 *    children: [
 *      { path: 'a', component: MainChild },
 *      { path: 'b', component: AuxChild, outlet: 'aux' }
 *    ]
 * }]
 * ```
 *
 * The router merges the parameters, data, and resolve of the componentless
 * parent into the parameters, data, and resolve of the children.
 *
 * This is especially useful when child components are defined
 * with an empty path string, as in the following example.
 * With this configuration, navigating to '/parent/10' creates
 * the main child and aux components.
 *
 * ```ts
 * [{
 *    path: 'parent/:id',
 *    children: [
 *      { path: '', component: MainChild },
 *      { path: '', component: AuxChild, outlet: 'aux' }
 *    ]
 * }]
 * ```
 *
 * ### Lazy Loading
 *
 * Lazy loading speeds up application load time by splitting the application
 * into multiple bundles and loading them on demand.
 * To use lazy loading, provide the `loadChildren` property in the `Route` object,
 * instead of the `children` property.
 *
 * Given the following example route, the router will lazy load
 * the associated module on demand using the browser native import system.
 *
 * ```ts
 * [{
 *   path: 'lazy',
 *   loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
 * }];
 * ```

/**
 * Function type definition for a data provider.
 *
 * A data provider can be used with the router to resolve data during navigation.
 * The router waits for the data to be resolved before the route is finally activated.
 *
 * A resolver can also redirect a `RedirectCommand` and the Angular router will use
 * it to redirect the current navigation to the new destination.
 *
 * @usageNotes
 *
 * The following example implements a function that retrieves the data
 * needed to activate the requested route.
 *
 * ```ts
 * interface Hero {
 *   name: string;
 * }
 * @Injectable()
 * export class HeroService {
 *   getHero(id: string) {
 *     return {name: `Superman-${id}`};
 *   }
 * }
 *
 * export const heroResolver: ResolveFn<Hero> = (
 *   route: ActivatedRouteSnapshot,
 *   state: RouterStateSnapshot,
 * ) => {
 *   return inject(HeroService).getHero(route.paramMap.get('id')!);
 * };
 *
 * bootstrapApplication(App, {
 *   providers: [
 *     provideRouter([
 *       {
 *         path: 'detail/:id',
 *         component: HeroDetailComponent,
 *         resolve: {hero: heroResolver},
 *       },
 *     ]),
 *   ],
 * });
 * ```
 *
 * And you can access to your resolved data from `HeroComponent`:
 *
 * ```ts
 * @Component({template: ''})
 * export class HeroDetailComponent {
 *   private activatedRoute = inject(ActivatedRoute);
 *
 *   ngOnInit() {
 *     this.activatedRoute.data.subscribe(({hero}) => {
 *       // do something with your resolved data ...
 *     });
 *   }
 * }
 * ```
 *
 * If resolved data cannot be retrieved, you may want to redirect the user
 * to a new page instead:
 *
 * ```ts
 * export const heroResolver: ResolveFn<Hero> = async (
 *   route: ActivatedRouteSnapshot,
 *   state: RouterStateSnapshot,
 * ) => {
 *   const router = inject(Router);
 *   const heroService = inject(HeroService);
 *   try {
 *     return await heroService.getHero(route.paramMap.get('id')!);
 *   } catch {
 *     return new RedirectCommand(router.parseUrl('/404'));
 *   }
 * };
 * ```
 *
 * When both guard and resolvers are specified, the resolvers are not executed until
 * all guards have run and succeeded.
 * For example, consider the following route configuration:
 *
 * ```ts
 * {
 *  path: 'base'
 *  canActivate: [baseGuard],
 *  resolve: {data: baseDataResolver}
 *  children: [
 *   {
 *     path: 'child',
 *     canActivate: [childGuard],
 *     component: ChildComponent,
 *     resolve: {childData: childDataResolver}
 *    }
 *  ]
 * }
 * ```
 * The order of execution is: baseGuard, childGuard, baseDataResolver, childDataResolver.

/**
 * @description
 *
 * When applied to an element in a template, makes that element a link
 * that initiates navigation to a route. Navigation opens one or more routed
 * components in one or more `<router-outlet>` locations on the page.
 *
 * Given a route configuration `[{ path: 'user/:name', component: UserCmp }]`,
 * the following creates a static link to the route:
 * `<a routerLink="/user/bob">link to user component</a>`
 *
 * You can use dynamic values to generate the link.
 * For a dynamic link, pass an array of path segments,
 * followed by the params for each segment.
 * For example, `['/team', teamId, 'user', userName, {details: true}]`
 * generates a link to `/team/11/user/bob;details=true`.
 *
 * Multiple static segments can be merged into one term and combined with
 * dynamic segments. For example, `['/team/11/user', userName, {details: true}]`
 *
 * The input that you provide to the link is treated as a delta to the current
 * URL. For instance, suppose the current URL is `/user/(box//aux:team)`. The
 * link `<a [routerLink]="['/user/jim']">Jim</a>` creates the URL
 * `/user/(jim//aux:team)`.
 * See {@link Router#createUrlTree} for more information.
 *
 * @usageNotes
 *
 * You can use absolute or relative paths in a link, set query parameters,
 * control how parameters are handled, and keep a history of navigation states.
 *
 * ### Relative link paths
 *
 * The first segment name can be prepended with `/`, `./`, or `../`.
 * * If the first segment begins with `/`, the router looks up the route from
 * the root of the app.
 * * If the first segment begins with `./`, or doesn't begin with a slash, the
 * router looks in the children of the current activated route.
 * * If the first segment begins with `../`, the router goes up one level in the
 * route tree.
 *
 * ### Setting and handling query params and fragments
 *
 * The following link adds a query parameter and a fragment to the generated
 * URL:
 *
 * ```html
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}"
 * fragment="education"> link to user component
 * </a>
 * ```
 * By default, the directive constructs the new URL using the given query
 * parameters. The example generates the link: `/user/bob?debug=true#education`.
 *
 * You can instruct the directive to handle query parameters differently
 * by specifying the `queryParamsHandling` option in the link.
 * Allowed values are:
 *
 *  - `'merge'`: Merge the given `queryParams` into the current query params.
 *  - `'preserve'`: Preserve the current query params.
 *
 * For example:
 *
 * ```html
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}"
 * queryParamsHandling="merge"> link to user component
 * </a>
 * ```
 *
 * `queryParams`, `fragment`, `queryParamsHandling`, `preserveFragment`, and
 * `relativeTo` cannot be used when the `routerLink` input is a `UrlTree`.
 *
 * See {@link UrlCreationOptions#queryParamsHandling}.
 *
 * ### Preserving navigation history
 *
 * You can provide a `state` value to be persisted to the browser's
 * [`History.state`
 * property](https://developer.mozilla.org/en-US/docs/Web/API/History#Properties).
 * For example:
 *
 * ```html
 * <a [routerLink]="['/user/bob']" [state]="{tracingId: 123}">
 *   link to user component
 * </a>
 * ```
 *
 * Use {@link Router#currentNavigation} to retrieve a saved Signal
 * navigation-state value. For example, to capture the `tracingId` during the `NavigationStart`
 * event:
 *
 * ```ts
 * // Get NavigationStart events
 * router.events.pipe(filter(e => e instanceof NavigationStart)).subscribe(e => {
 *   const navigation = router.currentNavigation();
 *   tracingService.trace({id: navigation.extras.state.tracingId});
 * });
 * ```
 *
 * ### RouterLink compatible custom elements
 *
 * In order to make a custom element work with routerLink, the corresponding
 * custom element must implement the `href` attribute and must list `href` in
 * the array of the static property/getter `observedAttributes`.
 *
 * @ngModule RouterModule
 *

/**
 *
 * @description
 *
 * Tracks whether the linked route of an element is currently active, and allows you
 * to specify one or more CSS classes to add to the element when the linked route
 * is active.
 *
 * Use this directive to create a visual distinction for elements associated with an active route.
 * For example, the following code highlights the word "Bob" when the router
 * activates the associated route:
 *
 * ```html
 * <a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
 * ```
 *
 * Whenever the URL is either '/user' or '/user/bob', the "active-link" class is
 * added to the anchor tag. If the URL changes, the class is removed.
 *
 * You can set more than one class using a space-separated string or an array.
 * For example:
 *
 * ```html
 * <a routerLink="/user/bob" routerLinkActive="class1 class2">Bob</a>
 * <a routerLink="/user/bob" [routerLinkActive]="['class1', 'class2']">Bob</a>
 * ```
 *
 * To add the classes only when the URL matches the link exactly, add the option `exact: true`:
 *
 * ```html
 * <a routerLink="/user/bob" routerLinkActive="active-link" [routerLinkActiveOptions]="{exact:
 * true}">Bob</a>
 * ```
 *
 * To directly check the `isActive` status of the link, assign the `RouterLinkActive`
 * instance to a template variable.
 * For example, the following checks the status without assigning any CSS classes:
 *
 * ```html
 * <a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive">
 *   Bob {{ rla.isActive ? '(already open)' : ''}}
 * </a>
 * ```
 *
 * You can apply the `RouterLinkActive` directive to an ancestor of linked elements.
 * For example, the following sets the active-link class on the `<div>`  parent tag
 * when the URL is either '/user/jim' or '/user/bob'.
 *
 * ```html
 * <div routerLinkActive="active-link" [routerLinkActiveOptions]="{exact: true}">
 *   <a routerLink="/user/jim">Jim</a>
 *   <a routerLink="/user/bob">Bob</a>
 * </div>
 * ```
 *
 * The `RouterLinkActive` directive can also be used to set the aria-current attribute
 * to provide an alternative distinction for active elements to visually impaired users.
 *
 * For example, the following code adds the 'active' class to the Home Page link when it is
 * indeed active and in such case also sets its aria-current attribute to 'page':
 *
 * ```html
 * <a routerLink="/" routerLinkActive="active" ariaCurrentWhenActive="page">Home Page</a>
 * ```
 *
 * NOTE: RouterLinkActive is a `ContentChildren` query.
 * Content children queries do not retrieve elements or directives that are in other components' templates, since a component's template is always a black box to its ancestors.
