Session 2025-11-21: Canvas Header Polish & Sidebar Icon Replacement

Session Summary

Completed Phase 4 (Canvas Header) with polished hover states, smooth transitions, and animated button expansions. Replaced all Lucide sidebar icons with custom Figma-exported icons featuring proper default and selected states.

Changes Made

1. Canvas Header Hover States ✅

Components Modified: BgColorSelector.tsx, CanvasSizeSelector.tsx

Removed hover animations:

• Removed text expansion animation on hover from CanvasSizeSelector
• Text labels now only appear when option is selected
• Added subtle #f0f2f4 hover background to both components

Updated transitions:

• Changed from 0.2s to 150ms ease-in-out for consistency
• Applied to both background color and canvas size selectors

2. Dimension Text Opacity ✅

Component Modified: CanvasSizeSelector.tsx

• Set dimension text (e.g., "1200x675") to 80% opacity for better visual hierarchy
• Improves readability while maintaining design aesthetic

3. Canvas Area Transitions ✅

Components Modified: Canvas.tsx, CanvasContainer.tsx, CanvasHeader.tsx

Canvas transitions:

• Width and height animate smoothly with 150ms ease-in-out
• Background color changes instantly (no transition) as requested
• Overflow hidden prevents layout shift during animation

Container transitions:

• Added all 0.15s ease-in-out transition to canvas container
• Header position adjusts smoothly when canvas size changes

4. Animated Button Expansion ✅

Component Modified: CanvasSizeSelector.tsx

Three-part animation system:

1. Width expansion/contraction:

   • Unselected: minWidth: '38px' (icon only)
   • Selected: Expands to fit icon + text
   • Transition: 150ms ease-in-out

2. Text fade-in/fade-out:

   • Unselected: opacity: 0
   • Selected: opacity: 0.8
   • Transition: 150ms ease-in-out

3. Text slide-in effect:

   • Unselected: translateX(-10px)
   • Selected: translateX(0)
   • Transition: 150ms ease-in-out

Implementation details:

• Text span always rendered (not conditional) to enable smooth transitions
• Button justifyContent switches between center (unselected) and flex-start (selected)
• Padding adjusts dynamically: 9px unselected, 10px selected
• All animations synchronized for smooth, professional effect

5. Sidebar Icon Replacement ✅

New Icon Components Created:

• IconLayout.tsx - Layout/grid icon with default (#545865) and selected (white) states
• IconText.tsx - Text "T" icon with default and selected states
• IconImage.tsx - Image/photo icon with default and selected states
• IconHuggy.tsx - Huggy mascot icon (single state as requested)

Component Modified: Sidebar.tsx

• Removed Lucide React imports (Layers, Smile, Image, Type)
• Replaced with custom Figma-exported icon components
• Icons loaded from localhost Figma MCP server URLs

Icon Implementation Pattern:

interface IconProps {
  selected?: boolean;
}

export default function Icon({ selected = false }: IconProps) {
  const imgDefault = "http://localhost:3845/assets/[hash].svg";
  const imgSelected = "http://localhost:3845/assets/[hash].svg";

  return (
    <div style={{ position: 'relative', width: '32px', height: '32px' }}>
      <img src={selected ? imgSelected : imgDefault} />
    </div>
  );
}

Huggy Icon Fix:

• Initially missed display: 'contents' CSS property on Face container
• This property makes container transparent in layout, allowing children to position correctly
• Fixed by adding display: 'contents' to Face container div

• src/components/CanvasHeader/BgColorSelector.tsx
• src/components/CanvasHeader/CanvasSizeSelector.tsx
• src/components/CanvasHeader/CanvasHeader.tsx
• src/components/Canvas/Canvas.tsx
• src/components/Canvas/CanvasContainer.tsx

Session 2025-11-20: Text Editing Bug Fixes

Session Summary

Fixed critical text editing issues and improved the text feature implementation. The main focus was resolving the missing bounding box problem and improving text editing behavior.

Issues Addressed

1. Delete Key Behavior ✅

Problem: When editing text, pressing Delete/Backspace would delete the entire text object instead of individual characters.

Solution: Added context-aware delete key handling in App.tsx:

// Check if user is editing text
const isEditingText = objects.some(obj => obj.type === 'text' && obj.isEditing);

// Delete selected object (only when NOT editing text)
if ((e.key === 'Delete' || e.key === 'Backspace') && selectedId && !isEditingText) {
  e.preventDefault();
  deleteSelected();
}

2. Missing Bounding Box (Critical) ✅

Problem: Transformer/bounding box not appearing when text objects were selected. Console showed Node: undefined repeatedly.

Root Cause: In Canvas.tsx line ~286, refs were passed as objects instead of callback functions:

// BROKEN:
shapeRef={{ current: shapeRefs.current.get(obj.id) || null }}

This created new objects on each render but never actually stored the node references.

Solution: Implemented callback ref pattern:

// FIXED:
shapeRef={(node: Konva.Node | null) => {
  if (node) {
    shapeRefs.current.set(obj.id, node);
  } else {
    shapeRefs.current.delete(obj.id);
  }
}}

Additional Changes:

• Updated type definitions in all components to accept both callback and RefObject refs:

  shapeRef?: ((node: Konva.Node | null) => void) | React.RefObject<Konva.Node>;
  

• Updated TextEditable.tsx, CanvasObject.tsx, and ImageRenderer to handle both ref patterns

3. Duplicate/Transparent Text During Editing ✅

Problem: Half-transparent text showing behind textarea during editing, creating visual duplicates.

Solution: Changed text opacity to 0 during editing in TextEditable.tsx:

<KonvaText
  // ... other props
  opacity={object.isEditing ? 0 : 1}  // Completely hide during edit
  listening={!object.isEditing}
/>

4. Textarea Rendering ✅

Problem: Initial attempt to render textarea inside Konva tree caused errors ("Konva has no node with the type textarea").

Solution: Moved textarea rendering completely outside Konva tree in Canvas.tsx:

{editingText && (
  <textarea
    ref={textareaRef}
    value={editingText.text}
    // ... positioned over canvas using fixed positioning
  />
)}

TypeScript Fixes

Fixed multiple TypeScript compilation errors:

• Removed unused imports (useState, getCanvasDimensions, KonvaText)
• Removed unused variables (editingTextId, setEditingTextId)
• Removed onTextChange prop (no longer needed, handled directly in Canvas.tsx)
• Fixed union type handling in useCanvasState.ts using DistributiveOmit type
• Fixed type assertion in updateSelected function

Files Modified

• src/App.tsx - Delete key behavior
• src/components/Canvas/Canvas.tsx - Callback refs, textarea rendering, transformer updates
• src/components/Canvas/CanvasObject.tsx - Ref handling, removed unused props
• src/components/Canvas/TextEditable.tsx - Opacity handling, ref pattern
• src/hooks/useCanvasState.ts - DistributiveOmit type, type assertions
• src/types/canvas.types.ts - (already had isEditing and isFixedSize properties)

Test Results

✅ Build successful without errors ✅ Dev server running at http://localhost:3000/ ✅ Bounding box now visible when selecting text objects ✅ Delete key works correctly in both contexts ✅ No duplicate/transparent text during editing ✅ Real-time font size adaptation working ✅ Text position remains stable between edit/view modes

Current Feature Status

Phase 9: Text Feature is now Core Complete:

• ✅ Text creation with button and 'T' keyboard shortcut
• ✅ Stage 1: Auto-growing text box on initial creation (68px default font)
• ✅ Stage 2: Fixed-size box with dynamic font scaling after first transform
• ✅ Real-time font size adaptation while typing
• ✅ Transformer/bounding box with blue border and white-filled corner handles
• ✅ Drag, scale, rotate functionality
• ✅ Double-click to edit
• ✅ Context-aware delete key
• ⚠️ Text toolbar (Phase 10) - Still TODO

Next Session

Start with Phase 4: Canvas Header - Implement background color selector and canvas size selector controls.

Session 2025-11-20 (Continued): Additional Text Feature Refinements

Additional Issues Fixed

5. Text Scaling on Transform ✅

Problem: When scaling up a text object, the font size would revert to default after releasing the mouse.

Root Cause: The fontSize property wasn't being updated during transformation - only width/height were changing.

Solution: Modified handleTransformEnd in Canvas.tsx:

// Handle text objects: scale fontSize and mark as fixed size
if (obj.type === 'text') {
  // Use the smaller scale factor to maintain readability
  const scaleFactor = Math.min(scaleX, scaleY);
  const newFontSize = Math.max(10, obj.fontSize * scaleFactor);

  return {
    ...updated,
    fontSize: newFontSize,
    isFixedSize: true
  };
}

Behavior: Font size now scales proportionally with the text box during transformation (minimum 10px).

6. Live Bounding Box Resize While Editing ✅

Problem: When deleting letters, the bounding box didn't shrink to hug the content, leaving empty space.

Solution: Modified handleTextareaChange in Canvas.tsx (lines 166-168):

// Always auto-grow/shrink box while editing (live resize)
const newWidth = Math.max(100, tempText.width() + 20);
const newHeight = Math.max(40, tempText.height() + 10);

Behavior: Text box now dynamically resizes in real-time as you type or delete characters.

7. Cursor Position on Double-Click ✅

Problem: When double-clicking text to edit, all text was selected instead of placing cursor at click position.

Solution:

1. Added calculateCursorPosition helper function in Canvas.tsx (lines 19-55)
2. Updated handleDoubleClick in TextEditable.tsx to capture click coordinates
3. Modified textarea focus logic to set cursor at calculated position

Behavior: Cursor now appears at the character closest to where you clicked.

8. Text Hint Box Positioning ✅

Problem: Text hint box appeared in the middle-right of sidebar instead of next to the Text button.

Solution: Repositioned hint box in Sidebar.tsx:

• Moved relative positioning to inner sidebar container
• Positioned hint box absolutely with left-[calc(100%+4px)] bottom-[5px]
• Added 4px gap between sidebar and hint box

Behavior: Hint box now appears directly to the right of the Text button at the same vertical level.

Files Modified

• src/components/Canvas/Canvas.tsx - Text scaling, live resize, cursor positioning
• src/components/Canvas/TextEditable.tsx - Capture click coordinates for cursor
• src/components/Canvas/CanvasObject.tsx - Updated type signatures for cursor positioning
• src/components/Sidebar/Sidebar.tsx - Hint box positioning

Test Results

✅ Font size scales proportionally when transforming text objects ✅ Bounding box shrinks/grows live while editing ✅ Cursor appears at exact click position on double-click ✅ Text hint box aligned with Text button ✅ All buttons in sidebar maintain consistent width

Phase 9 Status

Phase 9: Text Feature is now Fully Complete with all refinements:

• ✅ All core functionality working
• ✅ All edge cases handled
• ✅ All UX improvements implemented

Next Session

Ready to proceed with Phase 4: Canvas Header - Implement background color selector and canvas size selector controls.
