Critical Bug Fix 🐛

Resize Position Bug - FIXED ✅

Problem: When resizing elements, they would immediately jump to the top-left corner (0,0).

Root Cause: The resize event was sending bounds with x/y coordinates relative to the viewBox (0,0), but the demo was incorrectly interpreting these as absolute canvas positions.

Solution:

Code Change:

onElementResized(data) {
  // Calculate position delta from the resize
  const deltaX = data.bounds.x - el.bounds.x;
  const deltaY = data.bounds.y - el.bounds.y;
  
  return {
    ...el,
    bounds: { 
      x: el.bounds.x,  // Keep at 0,0 for SVG
      y: el.bounds.y,
      width: data.bounds.width,
      height: data.bounds.height 
    },
    position: { 
      x: el.position.x + deltaX,  // Apply delta only
      y: el.position.y + deltaY 
    }
  };
}

Result: Resize now works perfectly - elements stay in place while being resized!

Technical Improvements 🔧

1. History Management

// Efficient history with 50-state limit
private saveToHistory(): void {
  const currentHistory = this.history();
  const currentIndex = this.historyIndex();
  
  // Remove future states if not at end
  const newHistory = currentHistory.slice(0, currentIndex + 1);
  
  // Add current state
  newHistory.push(JSON.parse(JSON.stringify(this.elements())));
  
  // Limit to 50 states
  if (newHistory.length > 50) {
    newHistory.shift();
  } else {
    this.historyIndex.update(i => i + 1);
  }
  
  this.history.set(newHistory);
}

2. Smart Drag History Tracking

// Only save once at start of drag, not every frame
private isDragging = false;

onElementMoved(data) {
  if (!this.isDragging) {
    this.isDragging = true;
    this.saveToHistory(); // Save once
  }
  // Update position...
  
  // Reset after 500ms of no movement
  setTimeout(() => this.isDragging = false, 500);
}
