const fetchGraphQL = async (query, variables) => {
  const response = await fetch('/graphql', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': 'Bearer YOUR_AUTH_TOKEN'
    },
    body: JSON.stringify({ query, variables })
  });

  if (!response.ok) {
    const errorData = await response.json();
    throw new Error(`GraphQL error: ${errorData.errors[0].message}`);
  }

  return await response.json();
};

try {
  const data = await fetchGraphQL(`
    query GetUser($id: ID!) {
      user(id: $id) {
        name
        email
      }
    }
  `, { id: '123' });
  console.log(data);
} catch (error) {
  console.error('Failed to fetch data:', error.message);
