Description

This PR introduces improvements to the structural directive handling in Angular components, particularly for scenarios involving dynamic aliasing and attribute bindings. The changes aim to enhance readability and maintainability of templates while addressing issues with undefined objects in lifecycle methods.

• Purpose: To improve how aliases are used with Angular directives (*ngFor) and ensure @HostBinding works reliably without relying on undefined objects like document.
• Necessity: This change resolves potential runtime errors and improves the clarity and reusability of code.
• Improvements: It enhances the flexibility of Angular component templates and resolves edge cases related to attribute binding.

Related Issue(s)

• Resolves issues with undefined document object in server-side rendering contexts.
• Implements aliasing for *ngFor indices to improve code readability and reduce redundancy.

Changes

• Fixed: Resolved the issue where document was undefined in @HostBinding by using a platform-safe alternative (Renderer2).
• Added: Support for aliasing *ngFor indices using the as syntax for clarity.
• Updated: Refactored components to use improved structural directive patterns.
• Improved: Added comments and minor documentation updates for clarity.

How to Test

1. Test Host Binding Fix:

   • Verify that the data-focus attribute is correctly bound in both browser and server-side rendering contexts.
   • Ensure there are no runtime errors due to undefined document objects.

2. Test Index Aliasing:

   • Update templates using *ngFor and use the as aliasIndex syntax.
   • Ensure that the alias works as expected, and values are correctly rendered in the UI.

3. General Testing:

   • Run unit and integration tests to ensure no regressions.
   • Check the modified components across different browsers and devices for consistency.
