Development of Arnoz Headless Shopify Storefront
Krishna Singh
Arnoz — Headless Shopify Storefront
Project Overview
Arnoz is a production-grade headless eCommerce storefront built on TanStack Start and Shopify. The project was designed to deliver a fast, scalable shopping experience while maintaining complete control over performance, SEO, customer experience, and storefront customization.
Unlike traditional Shopify themes, Arnoz separates the frontend from Shopify's presentation layer, enabling modern React-based development, server-side rendering, edge deployment, and highly optimized user experiences.
Mobile Responsive UI
The Challenge
Traditional Shopify storefronts often limit flexibility, performance optimization, and developer experience. The goal was to create a modern commerce platform that:
Delivers fast page loads and excellent SEO.
Supports advanced product discovery and filtering.
Provides a seamless customer account experience.
Maintains secure communication with Shopify APIs.
Scales globally with edge deployment.
Uses a single, predictable data layer across the application.
Solution
I developed a fully headless Shopify storefront using TanStack Start, React 19, TanStack Query, and Shopify APIs.
The architecture introduces a server-only communication layer between the frontend and Shopify, ensuring that sensitive API tokens never reach the browser while maintaining excellent performance and security.
The application is deployed on Cloudflare Workers, bringing server-side rendering and commerce functionality closer to users worldwide.
