🛠️ Phase 1 Implementation Details

Component Structure:

Product/
├── index.tsx (main component)
├── components/
│   ├── ImageGallery.tsx
│   ├── ThumbnailSlider.tsx
│   ├── VariationSelector.tsx
│   ├── BuySection.tsx
│   ├── ProductTabs.tsx
│   ├── SpecificationTable.tsx
│   └── ProductMeta.tsx

State Management:

// Product page state
const [product, setProduct] = useState<Product | null>(null);
const [selectedImage, setSelectedImage] = useState<string>('');
const [selectedVariation, setSelectedVariation] = useState<any>(null);
const [selectedAttributes, setSelectedAttributes] = useState<Record<string, string>>({});
const [quantity, setQuantity] = useState(1);
const [activeTab, setActiveTab] = useState('description');

Key Features:

1. Thumbnail Slider

<div className="relative">
  {/* Prev Arrow */}
  <button onClick={scrollPrev} className="absolute left-0">
    <ChevronLeft />
  </button>
  
  {/* Scrollable Container */}
  <div ref={sliderRef} className="flex overflow-x-auto scroll-smooth gap-2">
    {images.map((img, i) => (
      <button
        key={i}
        onClick={() => setSelectedImage(img)}
        className={selectedImage === img ? 'ring-2 ring-primary' : ''}
      >
        <img src={img} />
      </button>
    ))}
  </div>
  
  {/* Next Arrow */}
  <button onClick={scrollNext} className="absolute right-0">
    <ChevronRight />
  </button>
</div>

2. Variation Selector

{product.attributes?.map(attr => (
  <div key={attr.name}>
    <label>{attr.name}</label>
    <select
      value={selectedAttributes[attr.name] || ''}
      onChange={(e) => handleAttributeChange(attr.name, e.target.value)}
    >
      <option value="">Choose {attr.name}</option>
      {attr.options.map(option => (
        <option key={option} value={option}>{option}</option>
      ))}
    </select>
  </div>
))}

3. Auto-Switch Variation Image

useEffect(() => {
  if (selectedVariation && selectedVariation.image) {
    setSelectedImage(selectedVariation.image);
  }
}, [selectedVariation]);

// Find matching variation
useEffect(() => {
  if (product?.variations && Object.keys(selectedAttributes).length > 0) {
    const variation = product.variations.find(v => {
      return Object.entries(selectedAttributes).every(([key, value]) => {
        return v.attributes[key] === value;
      });
    });
    setSelectedVariation(variation || null);
  }
}, [selectedAttributes, product]);
