# Phase 10 Plan 01: Node Autosizing Summary

**Generate nodes auto-resize to match output image/video aspect ratio with constrained dimensions (200-500px width, 200-600px height)**

## Performance

- **Duration:** 2 min
- **Started:** 2026-01-12T00:53:24Z
- **Completed:** 2026-01-12T00:55:46Z
- **Tasks:** 2
- **Files modified:** 3

## Accomplishments
- Created node dimension calculation utility with image/video dimension extraction
- GenerateImageNode auto-resizes when output image is set
- GenerateVideoNode auto-resizes when output video is set
- Aspect ratio maintained within size constraints

## Task Commits

Each task was committed atomically:

1. **Task 1: Create node dimension calculation utility** - `b0d0a4c` (feat)
2. **Task 2: Auto-resize generate nodes on output** - `52efbea` (feat)

## Files Created/Modified
- `src/utils/nodeDimensions.ts` - Utility for image/video dimension extraction and node size calculation
- `src/components/nodes/GenerateImageNode.tsx` - Added auto-resize effect on outputImage change
- `src/components/nodes/GenerateVideoNode.tsx` - Added auto-resize effect on outputVideo change

## Decisions Made
- Node sizing constraints: min 200px, max 500px width; min 200px, max 600px height
- Account for ~100px node chrome (header ~40px, controls ~60px)
- Use requestAnimationFrame to avoid React Flow update conflicts during resize
- Track previous output value to prevent redundant resize operations

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## Next Phase Readiness
- Phase 10 complete with 1/1 plans finished
- Node autosizing working for both image and video generation nodes
- Ready for Phase 11: UI Polish
