• Feature mapping: Document all current store features

Phase 2: Foundation Setup

• Hydrogen project initialization: Set up React Router architecture
• Component library creation: Build reusable UI components
• TypeScript configuration: Establish type safety and development tooling
• Testing framework setup: Implement automated testing

Phase 3: Incremental Migration

• Core templates first: Product pages, collection pages, cart functionality
• Custom features: Migrate specialized functionality and integrations
• Performance optimization: Implement code splitting and caching
• Quality assurance: Comprehensive testing and validation

Phase 4: Launch & Optimization

• Staged deployment: Gradual rollout with monitoring
• Performance validation: Verify Core Web Vitals improvements
• User experience testing: Ensure feature parity and improvements
• Team training: Onboard developers to new workflow

Real Migration Success Stories

Case Study 1: Fashion Retailer

Challenge: Liquid theme with slow mobile performance and difficult customization

Before Migration:

• Mobile Lighthouse score: 38
• Page load time: 5.8s
• Development time per feature: 12-16 hours
• Bug discovery: Post-deployment

After Hydrogen Migration:

• Mobile Lighthouse score: 95
• Page load time: 0.9s
• Development time per feature: 2-3 hours
• Bug discovery: Compile time (TypeScript)

Result: 45% increase in mobile conversion rate, 85% faster development

Case Study 2: Electronics Store

Challenge: Complex product configurator requiring extensive JavaScript

Before Migration:

• Heavy JavaScript bundle (680kb)
• Difficult state management
• No testing framework
• Frequent runtime errors

After Hydrogen Migration:

• Optimized bundle size (140kb)
• React state management
• Comprehensive test coverage
• TypeScript error prevention

Result: 60% reduction in runtime errors, 40% faster feature development

Technical Architecture Deep Dive

Hydrogen's React Router Advantages

// Component-based architecture with TypeScript
interface ProductCardProps {
  product: Product
  onAddToCart: (id: string) => Promise<void>
}

export function ProductCard({ product, onAddToCart }: ProductCardProps) {
  let [loading, setLoading] = useState(false)
  
  let handleAddToCart = async () => {
    setLoading(true)
    try {
      await onAddToCart(product.id)
    } catch (error) {
      // Error handling with TypeScript safety
      console.error('Failed to add to cart:', error)
    } finally {
      setLoading(false)
    }
  }

  return (
    <div className="product-card">
      <img src={product.featuredImage?.url} alt={product.title} />
      <h3>{product.title}</h3>
      <p>${product.priceRange.minVariantPrice.amount}</p>
      <button 
        onClick={handleAddToCart}
        disabled={loading}
      >
        {loading ? 'Adding...' : 'Add to Cart'}
      </button>
    </div>
  )
}

Liquid Template Limitations

<!-- No component reusability, no type safety -->
<div class="product-card">
  {% if product.featured_image %}
    <img src="{{ product.featured_image | img_url: 'medium' }}" 
         alt="{{ product.title }}">
  {% endif %}
  <h3>{{ product.title }}</h3>
  <p>{{ product.price | money }}</p>
  
  <!-- Form submission required, no client-side state -->
  <form action="/cart/add" method="post">
    <input type="hidden" name="id" value="{{ product.variants.first.id }}">
    <button type="submit">Add to Cart</button>
  </form>
</div>
