This sub-module is loaded by the path tutorials , so path here is going to be tutorials/input and will render the component InputComponent

The component Title has a field named message which is decorated with @Input(). This allows you to add a component and set the value of message.
| styleUrls: ['./title.component.scss'] | ||
| }) | ||
| export class TitleComponent { | ||
| @Input() |

This decorator allows you to set the value of this field in the html markup.
<app-title message="some message"></app-title>
| <div class="col-2"> | ||
| <ul class="Tutorials-menu"> | ||
| <li> | ||
| <a routerLink="/tutorials/input" [routerLinkActive]="'active'">@Input</a> |

You can use routerLinkActive to bind a class name that is going to be set on the element if the current route match the routerLink

Components this module exports.
If you want to use any of these components in another module you can import SharedModule (this module) in the other module, anything that is exported here will be available in the other end.

To test components that use router-outlet you need to import RouterTestingModule, a module specifically for tests.
