## 🚀 Migration Guide

### From React Query

```tsx
// 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

### Database Integration with React Queries

```tsx
import { useQuery, useMutation } from '@jutech-devs/quantum-query';
import { prismaAdapter } from './database';

// Custom hook for database operations
function useUsers() {
  return useQuery({
    queryKey: ['users'],
    queryFn: () => prismaAdapter.findMany('user', {
      where: { active: true },
      orderBy: { createdAt: 'desc' }
    }),
    // Database-specific optimizations
    database: {
      enableConnectionPooling: true,
      enableQueryOptimization: true,
      enableCaching: true
    }
  });
}

function useCreateUser() {
  return useMutation({
    mutationFn: (userData) => prismaAdapter.create('user', userData),
    onSuccess: () => {
      // Invalidate and refetch users
      queryClient.invalidateQueries(['users']);
    },
    // Optimistic updates
    onMutate: async (newUser) => {
      await queryClient.cancelQueries(['users']);
      const previousUsers = queryClient.getQueryData(['users']);
      
      queryClient.setQueryData(['users'], old => [
        ...old,
        { ...newUser, id: 'temp-' + Date.now() }
      ]);
      
      return { previousUsers };
    },
    onError: (err, newUser, context) => {
      queryClient.setQueryData(['users'], context.previousUsers);
    }
  });
}

// Component using database operations
function UserList() {
  const { data: users, isLoading, error } = useUsers();
  const createUserMutation = useCreateUser();
  
  const handleCreateUser = () => {
    createUserMutation.mutate({
      name: 'New User',
      email: 'newuser@example.com',
      active: true
    });
  };
  
  if (isLoading) return <div>Loading users...</div>;
  if (error) return <div>Error: {error.message}</div>;
  
  return (
    <div>
      <button onClick={handleCreateUser}>Add User</button>
      {users?.map(user => (
        <div key={user.id}>
          {user.name} - {user.email}
        </div>

### Framework-Agnostic Usage

Core functionality that works across all frameworks.

```tsx
// 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']);
  }
});
```
