🚀 How It Works Now

Complete Flow:

User Prompt → Backend → Claude AI → Layout Spec → SVG Generation → Frontend → SVG Parsing → tldraw Canvas

Response Types:

  1. SVG Response (Primary): Content-Type: image/svg+xml
  2. JSON Response (Fallback): Content-Type: application/json

SVG Elements Supported:

  • Rectangles: Headers, sidebars, content areas, cards
  • Text: Labels, titles, descriptions
  • Groups: Logical sections and containers
  • Shadows: Drop shadows and card shadows
  • Styling: Colors, fonts, borders, and spacing

🔧 Backend Implementation Details

Key Functions:

  • generate_svg_wireframe() - Main SVG generator
  • generate_header() - Header section rendering
  • generate_sidebar() - Sidebar rendering
  • generate_hero() - Hero section rendering
  • generate_section() - Main content sections
  • generate_grid_section() - Grid layouts
  • generate_form_section() - Form elements
  • generate_footer() - Footer rendering

SVG Features:

  • Filters: Shadow effects for cards and hero sections
  • Styling: Consistent color schemes and typography
  • Layout: Precise positioning and spacing
  • Responsiveness: Scalable vector graphics

API Endpoints:

  • POST /generate-wireframe - Generate SVG wireframe
  • GET /health - Health check endpoint

🎯 Frontend Implementation Details

SVG Parsing Functions:

  • parseSVGAndRender() - Main SVG parser
  • renderSVGElements() - Element iteration and routing
  • renderSVGRect() - Rectangle rendering
  • renderSVGCircle() - Circle rendering
  • renderSVGText() - Text rendering
  • renderSVGPath() - Path handling

Response Handling:

// Check response type
const contentType = response.headers.get('content-type')

if (contentType && contentType.includes('image/svg+xml')) {
  // Handle SVG response
  const svgString = await response.text()
  await parseSVGAndRender(editor, svgString)
} else {
  // Fallback to JSON
  const data = await response.json()
  await generateWireframeFromSpec(editor, data.wireframe)
}

🧪 Testing & Validation

Backend Testing:

  • SVG generation functions work correctly
  • All wireframe elements render properly
  • Error handling and fallbacks work
  • Response headers are set correctly

Frontend Testing:

  • TypeScript compilation passes
  • SVG parsing functions are implemented
  • Response type detection works
  • Fallback mechanisms are in place

🚀 Getting Started

1. Start Backend:

cd backend
pip install -r requirements.txt
python start_backend.py

2. Start Frontend:

cd my-app
npm install
npm run dev

3. Test Generation:

  1. Open the application
  2. Enter a prompt: "Dashboard with header, sidebar, and 3 stats cards"
  3. Click "Generate with AI"
  4. View the SVG-generated wireframe on the canvas

🎨 Example Prompts

  • Dashboard: "Dashboard with header, left sidebar, 3 stats cards, line chart, and footer"
  • Landing Page: "Landing page with hero section, feature grid, and contact form"
  • E-commerce: "Product page with image gallery, product details, and reviews"
  • Form: "Contact form with name, email, message, and submit button"

🔮 Benefits of This Implementation

1. Precision & Quality:

  • Exact Positioning: SVG provides pixel-perfect layouts
  • Rich Styling: Full support for colors, shadows, and effects
  • Scalable Graphics: Vector-based, resolution-independent

2. Performance:

  • Faster Rendering: Direct SVG parsing vs complex JSON processing
  • Better Memory Usage: Efficient SVG element handling
  • Reduced Complexity: Simpler frontend logic

3. Maintainability:

  • Backend Logic: SVG generation logic centralized in backend
  • Frontend Simplicity: Clean SVG parsing and rendering
  • Error Handling: Robust fallback mechanisms

🐛 Troubleshooting

Common Issues:

  1. SVG Not Rendering: Check content-type headers
  2. Parsing Errors: Validate SVG XML structure
  3. Backend Connection: Verify backend URL in config
  4. CORS Issues: Ensure backend CORS is configured

Debug Tips:

  • Check browser network tab for response types
  • Verify SVG content in browser dev tools
  • Monitor backend console for generation errors
  • Test with simple prompts first

📈 Future Enhancements

Planned Features:

  • Advanced SVG Elements: Complex paths, gradients, animations
  • Template System: Pre-built wireframe templates
  • Custom Styling: User-defined themes and color schemes
  • Export Options: PNG, PDF, and other formats
