🚀 Migration Guide

From React Query

// Before (React Query)
import { useQuery, useMutation, QueryClient, QueryClientProvider } from '@tanstack/react-query';

const queryClient = new QueryClient();

function App() {
  return (
    <QueryClientProvider client={queryClient}>
      <UserList />
    </QueryClientProvider>
  );
}

function UserList() {
  const { data, isLoading } = useQuery({
    queryKey: ['users'],
    queryFn: () => fetch('/api/users').then(res => res.json())
  });
  
  // ... rest of component
}

// After (Quantum Query) - Drop-in replacement
import { useQuery, useMutation, createQuantumQueryClient, QuantumQueryProvider } from '@jutech-devs/quantum-query';

const queryClient = createQuantumQueryClient();

function App() {
  return (
    <QuantumQueryProvider client={queryClient}>
      <UserList />
    </QuantumQueryProvider>
  );
}

function UserList() {
  const { data, isLoading } = useQuery({
    queryKey: ['users'],
    queryFn: () => fetch('/api/users').then(res => res.json()),
    // Optional: Add Quantum Query features
    aiOptimization: { intelligentCaching: true },
    quantumProcessing: { parallelFetching: true }
  });
  
  // ... rest of component (no changes needed)
}

Migration Checklist

• Replace imports from @tanstack/react-query to @jutech-devs/quantum-query
• Change QueryClient to createQuantumQueryClient()
• Change QueryClientProvider to QuantumQueryProvider
• Optionally add Quantum Query specific features
• Update TypeScript types if using custom types
• Test existing functionality (should work without changes)
• Gradually enable AI optimization and quantum processing
• Configure security and compliance settings for production

### 🤖 AI-Powered Optimization

The AI engine continuously learns from your application's usage patterns to optimize performance automatically.

```tsx
const { data, isLoading } = useQuery({
  queryKey: ['products', { category, filters }],
  queryFn: fetchProducts,
  aiOptimization: {
    intelligentCaching: true,      // AI determines cache TTL based on data volatility
    predictivePreloading: true,    // Preload data user is likely to request
    adaptiveRefetching: true,      // Adjust refetch intervals based on data freshness needs
    behaviorAnalysis: true,        // Learn from user interaction patterns
    performanceOptimization: true, // Automatically optimize query performance
    anomalyDetection: true         // Detect and handle unusual data patterns
  }
});

// Get AI insights about your queries
const insights = queryClient.ai.getInsights(['products']);
console.log('Predicted next queries:', insights.predictedQueries);
console.log('Optimal cache strategy:', insights.cacheStrategy);
console.log('Performance recommendations:', insights.recommendations);

⚛️ Quantum Computing Integration

Leverage quantum-inspired algorithms for unprecedented parallel processing capabilities.

const { data: complexData } = useQuery({
  queryKey: ['complex-calculation', parameters],
  queryFn: performComplexCalculation,
  quantumProcessing: {
    enableSuperposition: true,     // Process multiple calculation paths simultaneously

      'related-data-1',
      'related-data-2',
      'dependent-calculation'
    ],
    conflictResolution: 'quantum', // Use quantum algorithms for conflict resolution
    coherenceTime: 5000           // Maintain quantum coherence for 5 seconds
  }
});

// Create quantum entanglement between related queries
queryClient.quantum.entangleQueries([
  ['user', 'profile'],
  ['user', 'preferences'],
  ['user', 'settings']
]);

// Use quantum superposition for A/B testing
const { data: experimentData } = useQuantumSuperposition({
  experiments: [
    { queryKey: ['feature-a'], weight: 0.5 },
