Add navigation and routing

Learn how multiple views in the SPA are supported using AEM Pages and the SPA Editor SDK. Dynamic navigation is implemented using Angular routes and added to an existing Header component.

Objective

  1. Understand the SPA model routing options available when using the SPA Editor.
  2. Learn to use Angular routing to navigate between different views of the SPA.
  3. Implement a dynamic navigation that is driven by the AEM page hierarchy.

What you will build

This chapter adds a navigation menu to an existing Header component. The navigation menu is driven by the AEM page hierarchy and uses the JSON model provided by the Navigation Core Component.

Navigation implemented

Prerequisites

Review the required tooling and instructions for setting up a local development environment.

Get the code

  1. Download the starting point for this tutorial via Git:

    $ git clone git@github.com:adobe/aem-guides-wknd-spa.git
    $ cd aem-guides-wknd-spa
    $ git checkout Angular/navigation-routing-start
    
  2. Deploy the code base to a local AEM instance using Maven:

    $ mvn clean install -PautoInstallSinglePackage
    

    If using AEM 6.x add the classic profile:

    $ mvn clean install -PautoInstallSinglePackage -Pclassic
    
  3. Install the finished package for the traditional WKND reference site. The images provided by WKND reference site will be re-used on the WKND SPA. The package can be installed using AEM’s Package Manager.

    Package Manager install wknd.all

You can always view the finished code on GitHub or check the code out locally by switching to the branch Angular/navigation-routing-solution.

Inspect HeaderComponent updates

In previous chapters, the HeaderComponent component was added as a pure Angular component included via app.component.html. In this chapter, the HeaderComponent component is removed from the app and will be added via the Template Editor. This allows users to configure the navigation menu of the HeaderComponent from within AEM.

NOTE

Several CSS and JavaScript updates have already been made to the code base to start this chapter. To focus on core concepts, not all of the code changes are discussed. You can view the full changes here.

  1. In the IDE of your choice open the SPA starter project for this chapter.

  2. Beneath the ui.frontend module inspect the file header.component.ts at: ui.frontend/src/app/components/header/header.component.ts.

    Several updates have been made, including the addition of a HeaderEditConfig and a MapTo to enable the component to be mapped to an AEM component wknd-spa-angular/components/header.

    /* header.component.ts */
    ...
    const HeaderEditConfig = {
        ...
    };
    
    @Component({
    selector: 'app-header',
    templateUrl: './header.component.html',
    styleUrls: ['./header.component.scss']
    })
    export class HeaderComponent implements OnInit {
    @Input() items: object[];
        ...
    }
    ...
    MapTo('wknd-spa-angular/components/header')(withRouter(Header), HeaderEditConfig);
    

    Note the @Input() annotation for items. items will contain an array of navigation objects passed in from AEM.

  3. In the ui.apps module inspect the component definition of the AEM Header component: ui.apps/src/main/content/jcr_root/apps/wknd-spa-angular/components/header/.content.xml:

    <?xml version="1.0" encoding="UTF-8"?>
    <jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0"
        xmlns:jcr="http://www.jcp.org/jcr/1.0"
        jcr:primaryType="cq:Component"
        jcr:title="Header"
        sling:resourceSuperType="wknd-spa-angular/components/navigation"
        componentGroup="WKND SPA Angular - Structure"/>
    

    The AEM Header component will inherit all of the functionality of the Navigation Core Component via the sling:resourceSuperType property.

Add the HeaderComponent to the SPA template

  1. Open a browser and login to AEM, http://localhost:4502/. The starting code base should already be deployed.

  2. Navigate to the SPA Page Template: http://localhost:4502/editor.html/conf/wknd-spa-angular/settings/wcm/templates/spa-page-template/structure.html.

  3. Select the outer-most Root Layout Container and click its Policy icon. Be careful not to select the Layout Container un-locked for authoring.

    Select the root layout container policy icon

  4. Copy the current policy and create a new policy named SPA Structure:

    SPA Structure Policy

    Under Allowed Components > General > select the Layout Container component.

    Under Allowed Components > WKND SPA ANGULAR - STRUCTURE > select the Header component:

    Select header component

    Under Allowed Components > WKND SPA ANGULAR - Content > select the Image and Text components. You should have 4 total components selected.

    Click Done to save the changes.

  5. Refresh the page. Add the Header component above the un-locked Layout Container:

    add Header component to template

  6. Select the Header component and click its Policy icon to edit the policy.

    Click Header policy

  7. Create a new policy with a Policy Title of “WKND SPA Header”.

    Under the Properties:

    • Set the Navigation Root to /content/wknd-spa-angular/us/en.
    • Set the Exclude Root Levels to 1.
    • Uncheck Collect al child pages.
    • Set the Navigation Structure Depth to 3.

    Configure Header Policy

    This will collect the navigation 2 levels deep beneath /content/wknd-spa-angular/us/en.

  8. After saving your changes you should see the populated Header as part of the template:

    Populated header component

Create child pages

Next, create additional pages in AEM that will serve as the different views in the SPA. We will also inspect the hierarchical structure of the JSON model provided by AEM.

  1. Navigate to the Sites console: http://localhost:4502/sites.html/content/wknd-spa-angular/us/en/home. Select the WKND SPA Angular Home Page and click Create > Page:

    Create new page

  2. Under Template select SPA Page. Under Properties enter “Page 1” for the Title and “page-1” as the name.

    Enter the initial page properties

    Click Create and in the dialog pop-up, click Open to open the page in the AEM SPA Editor.

  3. Add a new Text component to the main Layout Container. Edit the component and enter the text: “Page 1” using the RTE and the H1 element (you will have to enter full-screen mode to change the paragraph elements)

    Sample content page 1

    Feel free to add additional content, like an image.

  4. Return to the AEM Sites console and repeat the above steps, creating a second page named “Page 2” as a sibling of Page 1. Add content to Page 2 so that it is easily identified.

  5. Lastly create a third page, “Page 3” but as a child of Page 2. Once completed the site hierarchy should look like the following:

    Sample Site Hierarchy

  6. In a new tab, open the JSON model API provided by AEM: http://localhost:4502/content/wknd-spa-angular/us/en.model.json. This JSON content is requested when the SPA is first loaded. The outer structure looks like the following:

    {
    "language": "en",
    "title": "en",
    "templateName": "spa-app-template",
    "designPath": "/libs/settings/wcm/designs/default",
    "cssClassNames": "spa page basicpage",
    ":type": "wknd-spa-angular/components/spa",
    ":items": {},
    ":itemsOrder": [],
    ":hierarchyType": "page",
    ":path": "/content/wknd-spa-angular/us/en",
    ":children": {
        "/content/wknd-spa-angular/us/en/home": {},
        "/content/wknd-spa-angular/us/en/home/page-1": {},
        "/content/wknd-spa-angular/us/en/home/page-2": {},
        "/content/wknd-spa-angular/us/en/home/page-2/page-3": {}
        }
    }
    

    Under :children you should see an entry for each of the pages created. The content for all of the pages is in this initial JSON request. Once, the navigation routing is implemented, subsequent views of the SPA will be loaded rapidly, since the content is already available client-side.

    It is not wise to load ALL of the content of a SPA in the initial JSON request, as this would slow down the initial page load. Next, lets look at how the heirarchy depth of pages are collected.

  7. Navigate to the SPA Root template at: http://localhost:4502/editor.html/conf/wknd-spa-angular/settings/wcm/templates/spa-app-template/structure.html.

    Click the Page properties menu > Page Policy:

    Open the page policy for SPA Root

  8. The SPA Root template has an extra Hierarchical Structure tab to control the JSON content collected. The Structure Depth determines how deep in the site hierarchy to collect child pages beneath the root. You can also use the Structure Patterns field to filter out additional pages based on a regular expression.

    Update the Structure Depth to “2”:

    Update structure depth

    Click Done to save the changes to the policy.

  9. Re-open the JSON model http://localhost:4502/content/wknd-spa-angular/us/en.model.json.

    {
    "language": "en",
    "title": "en",
    "templateName": "spa-app-template",
    "designPath": "/libs/settings/wcm/designs/default",
    "cssClassNames": "spa page basicpage",
    ":type": "wknd-spa-angular/components/spa",
    ":items": {},
    ":itemsOrder": [],
    ":hierarchyType": "page",
    ":path": "/content/wknd-spa-angular/us/en",
    ":children": {
        "/content/wknd-spa-angular/us/en/home": {},
        "/content/wknd-spa-angular/us/en/home/page-1": {},
        "/content/wknd-spa-angular/us/en/home/page-2": {}
        }
    }
    

    Notice that the Page 3 path has been removed: /content/wknd-spa-angular/us/en/home/page-2/page-3 from the initial JSON model.

    Later, we will observe how the AEM SPA Editor SDK can dynamically load additional content.

Implement the navigation

Next, implement the navigation menu with a new NavigationComponent. We could add the code directly in header.component.html but a better practice is to avoid large components. Instead, implement a NavigationComponent that could potentially be re-used later.

  1. Review the JSON exposed by the AEM Header component at http://localhost:4502/content/wknd-spa-angular/us/en.model.json:

    ...
    "header": {
        "items": [
        {
        "level": 0,
        "active": true,
        "path": "/content/wknd-spa-angular/us/en/home",
        "description": null,
        "url": "/content/wknd-spa-angular/us/en/home.html",
        "lastModified": 1589062597083,
        "title": "WKND SPA Angular Home Page",
        "children": [
                {
                "children": [],
                "level": 1,
                "active": false,
                "path": "/content/wknd-spa-angular/us/en/home/page-1",
                "description": null,
                "url": "/content/wknd-spa-angular/us/en/home/page-1.html",
                "lastModified": 1589429385100,
                "title": "Page 1"
                },
                {
                "level": 1,
                "active": true,
                "path": "/content/wknd-spa-angular/us/en/home/page-2",
                "description": null,
                "url": "/content/wknd-spa-angular/us/en/home/page-2.html",
                "lastModified": 1589429603507,
                "title": "Page 2",
                "children": [
                    {
                    "children": [],
                    "level": 2,
                    "active": false,
                    "path": "/content/wknd-spa-angular/us/en/home/page-2/page-3",
                    "description": null,
                    "url": "/content/wknd-spa-angular/us/en/home/page-2/page-3.html",
                    "lastModified": 1589430413831,
                    "title": "Page 3"
                    }
                ],
                }
            ]
            }
        ],
    ":type": "wknd-spa-angular/components/header"
    

    The hierarchical nature of the AEM pages are modeled in the JSON that can be used to populate a navigation menu. Recall that the Header component inherits all of the functionality of the Navigation Core Component and the content exposed through the JSON will be automatically mapped to the Angular @Input annotation.

  2. Open a new terminal window and navigate to the ui.frontend folder of the SPA project. Create a new NavigationComponent using the Angular CLI tool:

    $ cd ui.frontend
    $ ng generate component components/navigation
    CREATE src/app/components/navigation/navigation.component.scss (0 bytes)
    CREATE src/app/components/navigation/navigation.component.html (25 bytes)
    CREATE src/app/components/navigation/navigation.component.spec.ts (656 bytes)
    CREATE src/app/components/navigation/navigation.component.ts (286 bytes)
    UPDATE src/app/app.module.ts (2032 bytes)
    
  3. Next create a class named NavigationLink using the Angular CLI in the newly created components/navigation directory:

    $ cd src/app/components/navigation/
    $ ng generate class NavigationLink
    CREATE src/app/components/navigation/navigation-link.spec.ts (187 bytes)
    CREATE src/app/components/navigation/navigation-link.ts (32 bytes)
    
  4. Return to the IDE of your choice and open the file at navigation-link.ts at /src/app/components/navigation/navigation-link.ts.

    Open navigation-link.ts file

  5. Populate navigation-link.ts with the following:

    export class NavigationLink {
    
        title: string;
        path: string;
        url: string;
        level: number;
        children: NavigationLink[];
        active: boolean;
    
        constructor(data) {
            this.path = data.path;
            this.title = data.title;
            this.url = data.url;
            this.level = data.level;
            this.active = data.active;
            this.children = data.children.map( item => {
                return new NavigationLink(item);
            });
        }
    }
    

    This is a simple class to represent an individual navigation link. In the class constructor we expect data to be the JSON object passed in from AEM. This class will be used within both the NavigationComponent and HeaderComponent to easily populate the navigation structure.

    No data transformation is performed, this class is primarily created to strongly type the JSON model. Notice that this.children is typed as NavigationLink[] and that the constructor recursively creates new NavigationLink objects for each of the items in the children array. Recall that JSON model for the Header is hierarchical.

  6. Open the file navigation-link.spec.ts. This is the test file for the NavigationLink class. Update it with the following:

    import { NavigationLink } from './navigation-link';
    
    describe('NavigationLink', () => {
        it('should create an instance', () => {
            const data = {
                children: [],
                level: 1,
                active: false,
                path: '/content/wknd-spa-angular/us/en/home/page-1',
                description: null,
                url: '/content/wknd-spa-angular/us/en/home/page-1.html',
                lastModified: 1589429385100,
                title: 'Page 1'
            };
            expect(new NavigationLink(data)).toBeTruthy();
        });
    });
    

    Notice that const data follows the same JSON model inspected earlier for a single link. This is far from a robust unit test, however it should suffice to test the constructor of NavigationLink.

  7. Open the file navigation.component.ts. Update it with the following:

    import { Component, OnInit, Input } from '@angular/core';
    import { NavigationLink } from './navigation-link';
    
    @Component({
    selector: 'app-navigation',
    templateUrl: './navigation.component.html',
    styleUrls: ['./navigation.component.scss']
    })
    export class NavigationComponent implements OnInit {
    
        @Input() items: object[];
    
        constructor() { }
    
        get navigationLinks(): NavigationLink[] {
    
            if (this.items && this.items.length > 0) {
                return this.items.map(item => {
                    return new NavigationLink(item);
                });
            }
    
            return null;
        }
    
        ngOnInit() {}
    
    }
    
    

    NavigationComponent expects an object[] named items that is the JSON model from AEM. This class exposes a single method get navigationLinks() which returns an array of NavigationLink objects.

  8. Open the file navigation.component.html and update it with the following:

    <ul *ngIf="navigationLinks && navigationLinks.length > 0" class="navigation__group">
        <ng-container *ngTemplateOutlet="recursiveListTmpl; context:{ links: navigationLinks }"></ng-container>
    </ul>
    

    This generates an initial <ul> and calls the get navigationLinks() method from navigation.component.ts. An <ng-container> is used to make a call to a template named recursiveListTmpl and passes it the navigationLinks as a variable named links.

    Add the recursiveListTmpl next:

    <ng-template #recursiveListTmpl let-links="links">
        <li *ngFor="let link of links" class="{{'navigation__item navigation__item--' + link.level}}">
            <a [routerLink]="link.url" class="navigation__item-link" [title]="link.title" [attr.aria-current]="link.active">
                {{link.title}}
            </a>
            <ul *ngIf="link.children && link.children.length > 0">
                <ng-container *ngTemplateOutlet="recursiveListTmpl; context:{ links: link.children }"></ng-container>
            </ul>
        </li>
    </ng-template>
    

    Here the rest of the rendering for the navigation link is implemented. Note that the variable link is of type NavigationLink and all methods/properties created by that class are available. [routerLink] is used instead of normal href attribute. This allows us to link to specific routes in the app, without a full-page refresh.

    The recursive portion of the navigation is also implemented by creating another <ul> if the current link has a non-empty children array.

  9. Update navigation.component.spec.ts to add support for RouterTestingModule:

     ...
    + import { RouterTestingModule } from '@angular/router/testing';
     ...
     beforeEach(async(() => {
        TestBed.configureTestingModule({
    +   imports: [ RouterTestingModule ],
        declarations: [ NavigationComponent ]
        })
        .compileComponents();
     }));
     ...
    

    Adding the RouterTestingModule is required because the component uses [routerLink].

  10. Update navigation.component.scss to add some basic styles to the NavigationComponent:

    @import "~src/styles/variables";
    
    $link-color: $black;
    $link-hover-color: $white;
    $link-background: $black;
    
    :host-context {
        display: block;
        width: 100%;
    }
    
    .navigation__item {
        list-style: none;
    }
    
    .navigation__item-link {
        color: $link-color;
        font-size: $font-size-large;
        text-transform: uppercase;
        padding: $gutter-padding;
        display: flex;
        border-bottom: 1px solid $gray;
    
        &:hover {
            background: $link-background;
            color: $link-hover-color;
        }
    
    }
    

Update the header component

Now that the NavigationComponent has been implemented, the HeaderComponent must be updated to reference it.

  1. Open a terminal and navigate to the ui.frontend folder within the SPA project. Start the webpack dev server:

    $ npm start
    
  2. Open a browser tab and navigate to http://localhost:4200/.

    The webpack dev server should be configured to proxy the JSON model from a local instance of AEM (ui.frontend/proxy.conf.json). This will allow us to code directly against the content created in AEM from earlier in the tutorial.

    menu toggle working

    The HeaderComponent currently has the menu toggle functionality already implemented. Next, add the navigation component.

  3. Return to the IDE of your choice, and open the file header.component.ts at ui.frontend/src/app/components/header/header.component.ts.

  4. Update the setHomePage() method to remove the hard-coded String and use the dynamic props passed in by the AEM component:

    /* header.component.ts */
    import { NavigationLink } from '../navigation/navigation-link';
    ...
     setHomePage() {
        if (this.hasNavigation) {
            const rootNavigationLink: NavigationLink = new NavigationLink(this.items[0]);
            this.isHome = rootNavigationLink.path === this.route.snapshot.data.path;
            this.homePageUrl = rootNavigationLink.url;
        }
    }
    ...
    

    A new instance of NavigationLink is created based on items[0], the root of the navigation JSON model passed in from AEM. this.route.snapshot.data.path returns the path of the current Angular route. This value is used to determine if the current route is the Home Page. this.homePageUrl is used to populate the anchor link on the logo.

  5. Open header.component.html and replace the static placeholder for the navigation with a reference to the newly created NavigationComponent:

        <div class="header-navigation">
            <div class="navigation">
    -            Navigation Placeholder
    +           <app-navigation [items]="items"></app-navigation>
            </div>
        </div>
    

    [items]=items attribute passes the @Input() items from the HeaderComponent to the NavigationComponent where it will build out the navigation.

  6. Open header.component.spec.ts and add a declaration for the NavigationComponent:

        /* header.component.spect.ts */
    +   import { NavigationComponent } from '../navigation/navigation.component';
    
        describe('HeaderComponent', () => {
        let component: HeaderComponent;
        let fixture: ComponentFixture<HeaderComponent>;
    
        beforeEach(async(() => {
            TestBed.configureTestingModule({
            imports: [ RouterTestingModule ],
    +       declarations: [ HeaderComponent, NavigationComponent ]
            })
            .compileComponents();
        }));
    

    Since the the NavigationComponent is now used as part of the HeaderComponent it needs to be declared as part of the test bed.

  7. Save changes to any open files and return to the webpack dev server: http://localhost:4200/

    Completed header navigation

    Open the navigation by clicking the menu toggle and you should see the populated navigation links. You should be able to navigate to different views of the SPA.

Understand the SPA routing

Now that the navigation has been implemented, inspect the routing in AEM.

  1. In the IDE open the file app-routing.module.ts at ui.frontend/src/app.

    /* app-routing.module.ts */
    import { AemPageDataResolver, AemPageRouteReuseStrategy } from '@adobe/cq-angular-editable-components';
    import { NgModule } from '@angular/core';
    import { RouteReuseStrategy, RouterModule, Routes, UrlMatchResult, UrlSegment } from '@angular/router';
    import { PageComponent } from './components/page/page.component';
    
    export function AemPageMatcher(url: UrlSegment[]): UrlMatchResult {
        if (url.length) {
            return {
                consumed: url,
                posParams: {
                    path: url[url.length - 1]
                }
            };
        }
    }
    
    const routes: Routes = [
        {
            matcher: AemPageMatcher,
            component: PageComponent,
            resolve: {
                path: AemPageDataResolver
            }
        }
    ];
    @NgModule({
        imports: [RouterModule.forRoot(routes)],
        exports: [RouterModule],
        providers: [
            AemPageDataResolver,
            {
            provide: RouteReuseStrategy,
            useClass: AemPageRouteReuseStrategy
            }
        ]
    })
    export class AppRoutingModule {}
    

    The routes: Routes = []; array defines the routes or navigation paths to Angular component mappings.

    AemPageMatcher is a custom Angular router UrlMatcher, that matches anything that “looks like” a page in AEM that is part of this Angular application.

    PageComponent is the Angular Component that represents a Page in AEM, and the matched routes will invoke. The PageComponent will be inspected further.

    AemPageDataResolver, provided by the AEM SPA Editor JS SDK, is a custom Angular Router Resolver used to transform the route URL, which is the path in AEM including the.html extension, to the resource path in AEM, which is the page path less the extension.

    For example, the AemPageDataResolver transforms a route’s URL of content/wknd-spa-angular/us/en/home.html into a path of /content/wknd-spa-angular/us/en/home. This is used to resolve page’s content based on the path in the JSON model API.

    AemPageRouteReuseStrategy, provided by the AEM SPA Editor JS SDK, is a custom RouteReuseStrategy that prevents reuse of the PageComponent across routes. Otherwise content from page “A” might show up when navigating to page “B”.

  2. Open the file page.component.ts at ui.frontend/src/app/components/page/.

    ...
    export class PageComponent {
        items;
        itemsOrder;
        path;
    
        constructor(
            private route: ActivatedRoute,
            private modelManagerService: ModelManagerService
        ) {
            this.modelManagerService
            .getData({ path: this.route.snapshot.data.path })
            .then(data => {
                this.path = data[Constants.PATH_PROP];
                this.items = data[Constants.ITEMS_PROP];
                this.itemsOrder = data[Constants.ITEMS_ORDER_PROP];
            });
        }
    }
    

    The PageComponent is required to process the JSON retrieved from AEM and is used as the Angular component to render the routes.

    ActivatedRoute, which is provided by the Angular Router module, contains the state indicating which AEM Page’s JSON content should be loaded into this Angular Page component instance.

    ModelManagerService, gets the JSON data based on the route and maps the data to class variables path, items, itemsOrder. These will then be passed to the AEMPageComponent

  3. Open the file page.component.html at ui.frontend/src/app/components/page/

    <aem-page 
        class="structure-page" 
        [attr.data-cq-page-path]="path" 
        [cqPath]="path" 
        [cqItems]="items" 
        [cqItemsOrder]="itemsOrder">
    </aem-page>
    

    aem-page includes the AEMPageComponent. The variables path, items, and itemsOrder are passed to the AEMPageComponent. The AemPageComponent, provided via the SPA Editor JavaScript SDK’s will then iterate over this data and dynamically instantiate Angular components based on the JSON data as seen in the Map Components tutorial.

    The PageComponent is really just a proxy for the AEMPageComponent and it is the AEMPageComponent that does the majority of the heavy lifting to correctly map the JSON model to the Angular components.

Inspect the SPA routing in AEM

  1. Open a terminal and stop the webpack dev server if started. Navigate to the root of the project, and deploy the project to AEM using your Maven skills:

    $ cd aem-guides-wknd-spa
    $ mvn clean install -PautoInstallSinglePackage
    
    CAUTION

    The Angular project has some very strict linting rules enabled. If the Maven build fails, check the error and look for Lint errors found in the listed files.. Fix any issues found by the linter and re-run the Maven command.

  2. Navigate to the SPA homepage in AEM: http://localhost:4502/content/wknd-spa-angular/us/en/home.html and open your browser’s developer tools. Screenshots below are captured from Google Chrome browser.

    Refresh the page and you should see an XHR request to /content/wknd-spa-angular/us/en.model.json, which is the SPA Root. Notice that only three child pages are included based on the hierarchy depth configuration to the SPA Root template made earlier in the tutorial. This does not include Page 3.

    Initial JSON request - SPA Root

  3. With the developer tools open, navigate to Page 3:

    Page 3 Navigate

    Observe that a new XHR request is made to: /content/wknd-spa-angular/us/en/home/page-2/page-3.model.json

    Page three XHR Request

    The AEM Model Manager understands that the Page 3 JSON content is not available and automatically triggers the additional XHR request.

  4. Continue navigating the SPA using the various navigation links. Observe that no additional XHR requests are made, and that no full page refreshes occurs. This makes the SPA fast for the end-user and reduces unnecessary requests back to AEM.

    Navigation implemented

  5. Experiment with deep links by navigating directly to: http://localhost:4502/content/wknd-spa-angular/us/en/home/page-2.html. Observe that the browser’s back button continues to work.

Congratulations!

Congratulations, you learned how multiple views in the SPA can be supported by mapping to AEM Pages with the SPA Editor SDK. Dynamic navigation has been implemented using Angular routing and added to the Header component.

You can always view the finished code on GitHub or check the code out locally by switching to the branch Angular/navigation-routing-solution.
