• Backend API server (Node.js/Express)
• Database (PostgreSQL, MySQL, or MongoDB)
• OAuth authentication with Shopify
• Webhook handlers for real-time updates
• GraphQL/Admin API integration
• App Bridge for Shopify UI components

Development Workflow

1. Set up authentication: Implement OAuth flow to connect merchants to your app
2. Create admin interface: Build React components for merchant interaction
3. Build API endpoints: Create backend endpoints for app logic
4. Integrate Shopify APIs: Use Admin API or GraphQL to interact with store data
5. Handle webhooks: Set up webhooks for real-time updates (orders, products, etc.)
6. Implement billing: Set up Shopify Billing API for subscriptions (if applicable)
7. Add error handling: Implement proper error handling and logging

Key Technologies

Component	Technology	Purpose
Frontend	React	Admin interface UI
Backend	Node.js/Express	API server
Database	PostgreSQL	Data storage
API Communication	GraphQL/REST	Shopify API calls
Authentication	OAuth 2.0	Shopify app authentication
UI Components	App Bridge + Polaris	Shopify design system
Deployment	Heroku/AWS/Railway	Hosting

Step 5: Use Shopify APIs

Admin API

Access store data, manage products, orders, customers:

// Example: Fetch products using GraphQL
const query = `
  query getProducts {
    products(first: 10) {
      edges {
        node {
          id
          title
          handle
        }
      }
    }
  }
`;

Storefront API

For customer-facing features (public-facing apps):

// Example: Create checkout
const mutation = `
  mutation checkoutCreate($input: CheckoutCreateInput!) {
    checkoutCreate(input: $input) {
      checkout {
        id
        webUrl
      }
    }
  }
`;

Billing API

Handle app subscriptions and one-time charges:

// Example: Create recurring charge
const response = await fetch(`https://${shop}/admin/api/2024-01/recurring_application_charges.json`, {
  method: 'POST',
  headers: {
    'X-Shopify-Access-Token': accessToken,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    recurring_application_charge: {
      name: 'Pro Plan',
      price: 29.99,
      return_url: 'https://yourapp.com/confirm',
    }
  })
});

Step 6: Testing Your App

Development Store Testing

Testing Checklist

• Test OAuth installation flow
• Verify API calls work correctly
