Implementing Angular Router Links for Navigation

Angular's router allows for single-page application (SPA) navigation without full page reloads. A core component of this is the router link, which creates navigation links that leverage the Angular router. This challenge will guide you in creating and utilizing router links to navigate between different components within an Angular application.

Problem Description

You need to implement a component that displays a navigation menu with links to different pages within your Angular application. These links should utilize Angular's RouterLink directive to navigate to specific routes defined in your application's routing configuration. The component should dynamically generate the links based on a predefined array of route objects, each containing a path and a display name.

Key Requirements:

  • Dynamic Link Generation: The component should iterate through an array of route objects to create the necessary RouterLink directives.
  • Correct RouterLink Attributes: Each RouterLink should have the correct [routerLink] attribute set to the route's path.
  • Display Names: Each link should display a user-friendly name corresponding to the route.
  • Valid HTML: The generated HTML should be valid and well-formed.
  • Integration with Angular Router: The links should correctly trigger navigation when clicked, utilizing the Angular router.

Expected Behavior:

When the component is rendered, it should display a list of navigation links. Clicking on a link should navigate the user to the corresponding route defined in the application's routing configuration, without a full page reload.

Edge Cases to Consider:

  • Empty Route Array: Handle the case where the route array is empty gracefully (e.g., display a message indicating no navigation links are available).
  • Invalid Route Paths: While not strictly required for this challenge, consider how you might handle invalid or malformed route paths in a production environment.

Examples

Example 1:

Input: routes = [
  { path: '/home', name: 'Home' },
  { path: '/about', name: 'About' },
  { path: '/contact', name: 'Contact' }
]
Output:
<a [routerLink]="['/home']">Home</a>
<a [routerLink]="['/about']">About</a>
<a [routerLink]="['/contact']">Contact</a>
Explanation: The component iterates through the `routes` array and generates three `<a>` tags, each with a `routerLink` attribute pointing to a different route and displaying the corresponding name.

Example 2:

Input: routes = []
Output:
<p>No navigation links available.</p>
Explanation: The component handles the edge case of an empty `routes` array by displaying a message indicating that no navigation links are available.

Constraints

  • Angular Version: The solution should be compatible with Angular version 14 or higher.
  • Route Object Format: The route objects in the routes array should have the following format: { path: string, name: string }.
  • No External Libraries: The solution should not rely on any external libraries beyond the standard Angular framework.
  • Component Structure: You are expected to create a single Angular component to implement this functionality.

Notes

  • Consider using *ngFor to iterate over the routes array.
  • The RouterLink directive is a powerful tool for creating navigation links in Angular. Refer to the Angular documentation for more details: https://angular.io/api/router/RouterLink
  • Think about how to make the component reusable and configurable. The routes array could be passed as an input property.
  • Focus on creating a clean, readable, and maintainable solution.
