const { Shopify } = require('@shopify/shopify-api');

const stores = [
  { name: 'store1', accessToken: 'store1-access-token' },
  { name: 'store2', accessToken: 'store2-access-token' }
];

const clients = stores.map(store => new Shopify.Clients.Graphql(store.name, store.accessToken));

async function syncProductsAcrossStores() {
  try {
    const productsFromStore1 = await clients[0].query({ data: '{ products { id title } }' });
    const productsFromStore2 = await clients[1].query({ data: '{ products { id title } }' });

    // Logic to compare and synchronize products between stores
    // Example: Add products from Store 1 to Store 2 if not already present

    console.log('Products synced successfully.');
  } catch (error) {
    console.error('Error synchronizing products:', error);
  }
}

syncProductsAcrossStores();
