Library Details

Models

• ExternalLink: static link listed in navigation menu bar. eg, Employee Self Service site link. (Optional)
• InternalRoute: route for pages in your app.
• HeaderUser: used to display user name and/or original user name when impersonation.
• BannerLinks: static link listed in Uiowa branding bar. eg, Employee Self Service site link. Maximum two links. (Optional)

Features

• Responsive header layout with Hawkeye color styles

• Support custom "top-right" part of Uiowa branding bar. By default, "top-right" part of Uiowa branding bar shows External Links (if any) and Login link or User dropdown button. If you want to customize the "top-right" part, you can provide your content inside of uiowa-header tag. eg,

  <uiowa-header applicationName="My Awesome App" [internalRoutes]="myInternalRoutes">
    <div class="text-white">my content</div>
  </uiowa-header>

• Support application Nav menus with dropdown sub menus, as well as dividers in dropdown menu.

• Provide LoginService with default implementations for login() and logout() methods which correspond to click event from login and logout buttons. By default, you don't need to do extra work for login/logout. The two methods follow .NET Core convention redirect to routes account\login and account\logout, respectively. LoginService has a public member returnUri (string, default empty), which is the return uri after login.

  If you want to customize login and/or logout process, you can provide your customized service via dependency injection. eg,

  @NgModule({
    imports: [CommonModule, UiowaHeaderModule],
    declarations: [...],
    providers: [{ provide: LoginService, useClass: HawkIdLoginService }],
    exports: [UiowaHeaderModule, ...]
  })
  export class CoreModule {
    constructor(@Optional() @SkipSelf() core: CoreModule) {
      if (core) {
        throw new Error('Core Module can only be imported to AppModule.');
      }
    }
  }

• When user is impersonating and wants to stop impersonation, user dropdown will show a link which would emit a stopImpersonation event. You can handle this event accordingly.

• Follow web content accessibility guidelines.
