Description

Centralized overlay/drawer management system with signal-based store for coordinating slide-in panels, modals, and drawers across the application.

Implementation Details

  • Feature directory: src/Web/StellaOps.Web/src/app/layout/overlay-host/
  • Components:
    • overlay-host (src/Web/StellaOps.Web/src/app/layout/overlay-host/overlay-host.component.ts)
  • Store:
    • overlay.store (src/Web/StellaOps.Web/src/app/layout/overlay-host/overlay.store.ts)
  • Verification harness:
    • src/Web/StellaOps.Web/src/tests/overlays/overlay-host-component.spec.ts
  • Source: SPRINT_20260118_001_FE_shell_navigation_redesign.md

E2E Test Plan

  • Setup:
    • Log in with a user that has appropriate permissions
    • Navigate to the relevant page/section where this feature appears
    • Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
  • Core verification:
    • Verify the component renders drawer/modal overlays correctly
    • Verify escape and backdrop interactions close overlays deterministically
    • Verify open overlays receive keyboard focus for accessibility
  • Edge cases:
    • Verify graceful handling when backend API is unavailable (error state)
    • Verify responsive layout at different viewport sizes
    • Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
