@NikolaVetnic Can you do a first review? Once you approved, I will have a look myself.
This hopefully spares me some time because you find at least some of the issues.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit-tests for this file.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit tests for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository from git and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit tests.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

AdminUi/src/AdminUi/ClientApp/src/test.ts (1)

• 1-8: The setup for Angular testing environment initialization looks correct and follows best practices for setting up tests in Angular applications.

AdminUi/src/AdminUi/ClientApp/src/app/components/shared/breadcrumb/breadcrumb.component.html (1)

• 1-9: The breadcrumb component's HTML template uses Angular's structural directives effectively to iterate over breadcrumbHistory and conditionally display content. The use of *ngIf to handle the last breadcrumb differently (as a non-clickable span instead of a clickable a tag) is a good practice for usability.

AdminUi/src/AdminUi/ClientApp/src/app/app.component.html (1)

• 9-9: Inserting the <app-breadcrumb> component before the <router-outlet> in the main layout ensures that the breadcrumb navigation is visible across the application wherever the main layout is used. This placement is appropriate for the intended functionality.

AdminUi/src/AdminUi/ClientApp/src/app/components/shared/breadcrumb/breadcrumb.component.spec.ts (2)

• 1-23: The setup for BreadcrumbComponent tests with RouterTestingModule is correctly implemented. This setup is essential for testing components that depend on routing.
• 20-22: The test case to verify the component's creation is a good starting point for component testing. It ensures that the component can be instantiated without errors.

AdminUi/src/AdminUi/ClientApp/src/app/components/shared/breadcrumb/breadcrumb.component.ts (2)

• 1-28: The BreadcrumbComponent is well-structured, with clear separation of concerns. The use of BreadcrumbService for managing breadcrumb history and Router for subscribing to navigation events is appropriate. The component's logic for updating the breadcrumb history on navigation events is correctly implemented.
• 25-28: The method onBreadcrumbClick correctly clears the breadcrumb history after a specified index. This functionality is essential for maintaining accurate navigation history.

AdminUi/src/AdminUi/ClientApp/src/app/services/auth-service/auth.service.ts (2)

• 7-7: The import of BreadcrumbService is correctly added to support breadcrumb navigation management upon user logout. This addition demonstrates good integration of new features with existing services.
• 54-54: The call to clearBreadcrumbHistoryAfterIndex(0) in the logout method is a thoughtful addition, ensuring that breadcrumb history is cleared upon user logout, which is a good security and usability practice.

AdminUi/src/AdminUi/ClientApp/src/app/app-routing.module.ts (1)

• 17-24: Adding data properties with breadcrumb labels to routes is correctly implemented. This approach allows for dynamic breadcrumb generation based on the current route, enhancing the application's navigability.

AdminUi/src/AdminUi/ClientApp/src/app/services/breadcrumb-service/breadcrumb.service.ts (2)

• 1-34: The BreadcrumbService is well-implemented, with a clear responsibility for managing breadcrumb navigation history. The use of session storage to persist breadcrumb history across page reloads is a good practice for user experience.
• 36-111: The logic for updating, trimming, and generating breadcrumb history is correctly implemented. The methods updateBreadcrumbHistory, trimBreadcrumbHistory, and generateBreadcrumbHistory are well-designed, ensuring that the breadcrumb history is accurately maintained and does not exceed the maximum history size.

AdminUi/src/AdminUi/ClientApp/src/app/services/breadcrumb-service/breadcrumb.service.spec.ts (1)

• 1-171: The tests for BreadcrumbService cover essential functionalities, such as ensuring the service is created, managing breadcrumb history, and handling edge cases like negative indices. The use of a mock ActivatedRoute and Router for testing is correctly implemented. These tests are comprehensive and well-structured.

AdminUi/src/AdminUi/ClientApp/src/app/app.module.ts (1)

• 52-52: The addition of BreadcrumbComponent to the declarations array in AppModule is correctly done. This step is necessary for the Angular framework to recognize and use the BreadcrumbComponent throughout the application.
