E-Commerce Project Plan using Shopify API

As a Senior Software Engineer, I'll help you plan an e-commerce project using the Shopify API. We'll break this down into the following key sections:

  1. Project Overview & Architecture

  2. Core Features & Services

  3. Third-Party Integrations

  4. UI/UX Design

  5. API Design

1. Project Overview & Architecture

The project will be a fully functional e-commerce platform leveraging the Shopify API for core e-commerce capabilities (such as product management, inventory, orders, payments, etc.) while building custom features around it. The idea is to extend Shopify's capabilities with a custom frontend and additional services, integrating multiple third-party solutions to handle specific functionalities (e.g., shipping, marketing, etc.).

High-Level Architecture:

  • Frontend: React or Next.js (for a modern, fast user interface)

  • Backend: Node.js + Express (or Next.js with API routes)

  • Database: MongoDB or PostgreSQL (for storing custom data, user profiles, wishlists, etc.)

  • Authentication: Shopify OAuth (to integrate with the Shopify store admin panel)

  • Hosting: AWS, Vercel, or Netlify for deployment (depending on your scale and requirements)

  • CDN: Cloudflare or Shopify’s built-in CDN for assets

  • Payment Processing: Shopify Payments (with optional integration with Stripe/PayPal for custom processing)
