🐛 TROUBLESHOOTING GUIDE

🔴 Common Issues & Solutions

1. Ollama Connection Errors

# Check if Ollama is running
curl http://localhost:11434/api/version

# Restart Ollama service
ollama serve

# Verify model availability
ollama list | grep gemma

2. Database Connection Issues

# Test PostgreSQL connection
psql -h localhost -U postgres -d chatdb

# Reset database schema
cd backend && npx prisma db push --force-reset

3. Frontend Build Errors

# Clear Next.js cache
rm -rf .next && npm run dev

# Check TypeScript errors
npm run type-check

4. Port Conflicts

# Kill process using port 3000/5000
lsof -ti:3000 | xargs kill -9
lsof -ti:5000 | xargs kill -9

5. Search/Export Not Working

Ensure messages exist in current chat
Check browser console for JavaScript errors
Verify React components are properly imported

6. Mobile Responsive Issues

Clear browser cache and reload
Test on different devices/browsers
Check viewport meta tag in _app.tsx

✨ **Clean Architecture**: Only production-ready components included
```### **🔧 Adding New Features**

**1. Backend API Endpoint:**

```javascript
// backend/src/routes/chatRoutes.js
router.post("/api/new-feature", async (req, res) => {
  // Your feature logic here
});

2. Frontend Component:

// frontend/src/components/NewFeature.tsx
import React from "react";

const NewFeature: React.FC = () => {
  return <div className="feature-container">{/* Your component JSX */}</div>;
};

3. Database Schema Update:

// backend/prisma/schema.prisma
model NewTable {
  id        String   @id @default(cuid())
  // Add your fields
  createdAt DateTime @default(now())
}

📈 Performance Optimizations

Database:

Indexed frequently queried fields (chatId, timestamp)
Connection pooling for concurrent requests
Optimized queries with Prisma

Frontend:

Code splitting with Next.js dynamic imports
Image optimization with Next.js Image component
Memoized expensive computations with useMemo
Debounced search to reduce API calls

Caching Strategy:

Browser caching for static assets
React Query for API response caching
Local storage for theme preferences
