Phase 6 Plan 02: Renderer Wiring Summary

YearModeRenderer wired into strategy-pattern orchestrator, heatmap.ts reduced from 413 to 116 lines, all 62 tests passing

Performance

• Duration: 3 min
• Started: 2026-04-09T07:44:14Z
• Completed: 2026-04-09T07:47:26Z
• Tasks: 2 automated + 1 checkpoint (pending human verification)
• Files modified: 6

Accomplishments

• Created YearModeRenderer that produces identical SVG output to v1.0 renderHeatmap()
• Rewrote heatmap.ts as slim orchestrator using registry dispatch pattern
• Migrated all test imports to new module locations -- 62/62 tests pass across 9 files
• Added metric-aware cell fill (forward-compatible for hours/count toggle)

Task Commits

Each task was committed atomically:

1. Task 1: Create YearModeRenderer and rewrite heatmap.ts orchestrator - aab3915 (feat)
2. Task 2: Migrate test imports and verify full suite - 881718e (refactor)
3. Task 3: Visual regression check - checkpoint (pending human verification)

Files Created/Modified

• assets/src/renderers/year.ts - YearModeRenderer implementing ModeRenderer with full year heatmap rendering
• assets/src/renderers/types.ts - Added emptyMessage to RenderContext
• assets/src/heatmap.ts - Slim orchestrator (116 lines, down from 413)
• assets/test/heatmap.test.ts - Migrated from renderHeatmap to YearModeRenderer.render()
• assets/test/stats.test.ts - Import path changed to shared/stats
• assets/test/interaction.test.ts - Migrated from renderHeatmap to YearModeRenderer.render()

Decisions Made

• Cell fill uses ctx.state.metric === 'hours' ? d.entry.hours : d.entry.count for forward-compatible metric toggle (no-op for v1.0 where metric is always 'hours')
• emptyMessage added as optional field on RenderContext to preserve "No tracking data for this project" filtered empty message

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Checkpoint: Visual Regression Check

Status: Automated verification passed (build:dev succeeds). Manual visual verification pending.

Verification steps for human:

1. Start local Kimai dev environment
2. Navigate to dashboard
3. Verify heatmap renders identically: cells colored green, tooltip on hover, click navigates to timesheet, stats row present, filter dropdown works, resize re-renders
4. Check browser console -- no errors
5. Verify typeof KimaiHeatmap.init === 'function' in console

Next Phase Readiness

• Renderer architecture fully wired -- adding new modes requires only implementing ModeRenderer and calling registerRenderer()
• Ready for Plan 03 (mode switcher UI and additional renderers)

Self-Check: PASSED

• All 6 created/modified files exist on disk
• Both task commits verified (aab3915, 881718e)
• Full test suite: 62/62 passing across 9 files
• esbuild: produces valid IIFE bundle (38.9kb minified)
