const { Shopify, ApiVersion } = require('@shopify/shopify-api');
const jwt = require('jsonwebtoken');

const shop = 'your-shop-name.myshopify.com';
const accessToken = 'your-access-token';
const JWT_SECRET = 'your-jwt-secret';

const client = new Shopify.Clients.Graphql(shop, accessToken);

// Middleware to verify JWT token
function authenticateToken(req, res, next) {
  const authHeader = req.headers['authorization'];
  const token = authHeader && authHeader.split(' ')[1];

  if (token == null) return res.sendStatus(401);

  jwt.verify(token, JWT_SECRET, (err, user) => {
    if (err) return res.sendStatus(403);
    req.user = user;
    next();
  });
}

// Example of a secured GraphQL query
async function fetchProductDetails() {
  const query = `
  {
    products(first: 1) {
      edges {
        node {
          id
          title
        }
      }
    }
  }`;

  try {
    const result = await client.query({ data: query });
    console.log('Product Details:', result.products.edges.map(edge => edge.node));
  } catch (error) {
    console.error('Secure Error Handling:', error);
  }
}

// Express.js route with authentication
const express = require('express');
const app = express();
app.get('/products', authenticateToken, (req, res) => {
  fetchProductDetails().then(response => res.json(response));
});

app.listen(3000, () => {
  console.log('Server running on port 3000');
});
