🚀 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
    parallelFetching: true,        // Execute related queries in parallel

      '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 },

Framework-Agnostic Usage

Core functionality that works across all frameworks.

// Universal query client setup
import { createQuantumQueryClient } from '@jutech-devs/quantum-query';

const queryClient = createQuantumQueryClient({
  // Framework adapters auto-detect environment
  autoDetectFramework: true,
  
  // Universal configuration
  defaultOptions: {
    queries: {
      staleTime: 5 * 60 * 1000,
      cacheTime: 30 * 60 * 1000,
      retry: 3
    }
  },
  
  // Framework-specific optimizations
  frameworkOptimizations: {
    enableSSROptimization: true,
    enableHydrationOptimization: true,
    enableBundleSplitting: true,
    enableTreeShaking: true
  }
});

// Universal hooks (work in React, Vue, Svelte)
const { data, isLoading, error } = useQuery({
  queryKey: ['universal-data'],
  queryFn: () => fetch('/api/data').then(res => res.json()),
  
  // Framework-agnostic options
  universal: {
    enableSSR: true,
    enablePrefetching: true,
    enableOptimisticUpdates: true
  }
});

// Universal mutations
const mutation = useMutation({
  mutationFn: (data) => fetch('/api/data', {
    method: 'POST',
    body: JSON.stringify(data)
  }),
  onSuccess: () => {
    queryClient.invalidateQueries(['universal-data']);
  }
});

🏗️ Enterprise Backend Integration

Comprehensive Database Support

Support for 10+ database systems with unified API and enterprise features.

import { createDatabaseAdapter } from '@jutech-devs/quantum-query/backend';

// SQL Databases

  connection: prismaClient,
  retry: { attempts: 3, delay: 1000, backoff: 'exponential' },
  metrics: { enabled: true, onQuery: (op, duration, success) => console.log(op, duration) },
  pooling: { min: 5, max: 20, acquireTimeoutMillis: 5000 }
});

// NoSQL Databases
const mongoAdapter = createDatabaseAdapter({
  type: 'mongodb',
  connection: mongoClient.db('myapp'),
  caching: { enabled: true, ttl: 300 }
});

// Cloud Databases
const supabaseAdapter = createDatabaseAdapter({
  type: 'supabase',
  connection: supabaseClient
});

// Bulk operations with batching
const users = await prismaAdapter.createMany('users', userData, {
  batchSize: 100,
  parallel: true
});

// Health monitoring
const health = await prismaAdapter.checkHealth();
console.log('Database health:', health.connected, health.latency);

// Performance metrics
