# Tech tracking
tech-stack:
  added: []
  patterns:
    - EmptyState as shared component for zero-data states across pages
    - Delete confirmation dialog pattern with pendingDelete state, spinner, and inline error
    - loading guard to prevent empty-state flash on initial fetch

key-files:
  created:
    - frontend/src/components/EmptyState.tsx
  modified:
    - frontend/src/pages/DashboardPage.tsx
    - frontend/src/pages/CategoriesPage.tsx

key-decisions:
  - "EmptyState is a shared component (not per-page) — icon, heading, subtext, and optional CTA are all props"
  - "Delete dialog does not auto-close on error — user must read the ON DELETE RESTRICT message and dismiss manually"
  - "CategoriesPage uses a loading state (initialized true) to prevent empty-state flash before first fetch completes"

patterns-established:
  - "EmptyState pattern: icon + heading + subtext + optional action button in centered flex column"
  - "Delete confirmation pattern: pendingDelete state object, confirmDelete async handler, inline deleteError display"

# Phase 3 Plan 02: Delete Confirmation and Empty States Summary

**Shared EmptyState component plus delete confirmation dialog with spinner and ON DELETE RESTRICT error handling for CategoriesPage**

## Performance

- **Duration:** 5 min
- **Started:** 2026-03-11T21:30:37Z
- **Completed:** 2026-03-11T21:33:00Z
- **Tasks:** 2
- **Files modified:** 3

## Accomplishments

- Created shared `EmptyState` component with icon, heading, subtext, and optional CTA button
- Wired EmptyState into DashboardPage (no-budgets case and no-current-budget case) and CategoriesPage (no-categories case with loading guard)
- Replaced direct delete in CategoriesPage with confirmation dialog using `pendingDelete` state, spinner feedback, and inline error display for ON DELETE RESTRICT failures

## Task Commits

Each task was committed atomically:

1. **Task 1 + Task 2: EmptyState, Dashboard empty state, Categories empty state + delete confirmation dialog** - `4fc6389` (feat)

**Plan metadata:** (docs commit — pending)

_Note: Task 1 and Task 2 were both implemented in the same editing session and verified together before commit._

## Files Created/Modified

- `frontend/src/components/EmptyState.tsx` - Shared empty state component with icon, heading, subtext, and optional CTA
- `frontend/src/pages/DashboardPage.tsx` - Added EmptyState for no-budgets and no-current-budget cases; imports EmptyState and FolderOpen
- `frontend/src/pages/CategoriesPage.tsx` - Added loading state, EmptyState for no-categories case, delete confirmation dialog with spinner and error handling

## Decisions Made

- EmptyState is a generic shared component with all content as props — keeps the component reusable across any future zero-data scenarios
- Delete dialog stays open on error — intentional so users can read the ON DELETE RESTRICT constraint message before dismissing
- CategoriesPage `loading` state initialized to `true` and set to `false` in a `finally` block — prevents empty-state flash before data arrives

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- EmptyState component is ready for reuse in any other page needing zero-data messaging
- Delete confirmation pattern established — can be replicated for budget item deletion or other destructive actions in Phase 3 plans
- No blockers for remaining Phase 3 plans
