Node.js
Headless Checkout Orchestration Built with Node.js
We built a Node.js headless checkout orchestration layer to coordinate payments, inventory, order management, and commerce services for a faster, more flexible checkout experience.
Architecture
Node.js services coordinating Razorpay payments, inventory validation, and OMS webhooks through an API-first checkout layer.
Tech Stack
Node.js, MedusaJS, Next.js, PostgreSQL
Performance Gains
40% faster checkout compared with the previous Shopify Liquid theme.
How the Headless Checkout Works
The system separates checkout logic from the storefront and coordinates commerce operations through Node.js services. The checkout layer manages payment processing, inventory validation, order creation, and OMS webhooks while MedusaJS handles core commerce operations.
Checkout Flow
Next.js → Node.js Checkout API → MedusaJS → Razorpay → Inventory → OMS
This architecture gives the commerce platform greater control over checkout logic while making it easier to integrate additional payment, inventory, shipping, and order-management services.
