# Phase 02, Plan 01: Month Navigation and Chart Infrastructure Summary
|
|
|
|
**useMonthParam hook and MonthNavigator component for URL-based month selection, plus 10 new chart/navigation i18n keys in EN and DE**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** ~2 min
|
|
- **Started:** 2026-03-16T12:01:18Z
|
|
- **Completed:** 2026-03-16T12:03:21Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 4
|
|
|
|
## Accomplishments
|
|
- useMonthParam hook reads/writes `?month=YYYY-MM` from URL with current month fallback and year-rollover-safe navigation
|
|
- MonthNavigator renders prev/next chevron buttons and a Select dropdown listing available budget months with locale-aware formatting
|
|
- Added 10 new i18n keys under `dashboard.*` for chart labels, month navigation, and empty states in both English and German
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create useMonthParam hook and MonthNavigator component** - `4481950` (feat)
|
|
2. **Task 2: Add chart and month navigation i18n keys** - `42bf1f9` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `src/hooks/useMonthParam.ts` - Custom hook wrapping useSearchParams for month URL state with setMonth and navigateMonth
|
|
- `src/components/dashboard/MonthNavigator.tsx` - Prev/next arrow buttons + Select dropdown for month selection
|
|
- `src/i18n/en.json` - Added monthNav, noData, expenseDonut, incomeChart, spendChart, budgeted, actual, noBudgetForMonth, createBudget, generateFromTemplate keys
|
|
- `src/i18n/de.json` - German translations for all 10 new dashboard keys
|
|
|
|
## Decisions Made
|
|
- MonthNavigator uses the shadcn Select component (not a popover or custom dropdown) for month selection -- consistent with existing form patterns in the project
|
|
- formatMonthLabel uses `Date.toLocaleDateString(undefined, { month: "long", year: "numeric" })` for locale-aware month display rather than manual string formatting
|
|
- ChartEmptyState component was already created during Phase 1 scaffolding -- verified it matches the plan specification exactly, so no changes were needed
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 1 - Already Exists] Skipped ChartEmptyState component creation**
|
|
- **Found during:** Task 2 (ChartEmptyState and i18n keys)
|
|
- **Issue:** ChartEmptyState component already existed from Phase 1 setup
|
|
- **Fix:** Skipped creation, added only the i18n keys
|
|
- **Verification:** Component exists and exports correctly
|
|
- **Committed in:** 42bf1f9 (Task 2 commit)
|
|
|
|
---
|
|
|
|
**Total deviations:** 1 auto-fixed (1 already exists)
|
|
**Impact on plan:** No scope creep — component existed, only i18n work needed.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- useMonthParam hook ready for consumption by DashboardPage refactor (Plan 03)
|
|
- MonthNavigator ready to be placed in PageShell action slot (Plan 03)
|
|
- ChartEmptyState ready for use in chart components (Plans 02)
|
|
- All chart i18n keys available for chart components (Plan 02)
|
|
|
|
