What is shopify-hydrogen?

A guide to building a custom Shopify storefront with Hydrogen, Shopify’s React framework for headless stores, and deploying it to Shopify’s Oxygen hosting.

Use it to create product pages, carts, customer accounts, Storefront API queries, caching, streaming, SEO, and third-party service integrations.

It helps when Shopify’s standard theme does not provide enough control over the storefront’s design, user experience, or integrations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.02798
Opus 5.5	$0.00011	$0.01119
Sonnet 5.5	$0.00006	$0.00560

Security

Grade A, and why

shopify-hydrogen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Shopify Hydrogen

Overview

Hydrogen is Shopify's official React-based framework for building headless storefronts, built on top of Remix and deployed to Oxygen (Shopify's edge hosting). It provides first-class primitives for the Storefront API — product queries, cart management, customer accounts — alongside Shopify-specific components and hooks that handle caching, streaming, and SEO automatically. This skill covers scaffolding a Hydrogen project, querying the Storefront API, implementing cart functionality, and deploying to Oxygen.

When to Use This Skill

When building a custom Shopify storefront with full design and UX control
When the default Shopify Online Store theme is too limiting for your design requirements
When you need server-side rendering, streaming, and edge-deployed performance
When integrating third-party services (loyalty, CMS, personalization) directly into the storefront
When you want a Shopify-managed backend with a completely custom frontend stack

Prerequisites & Platform Notes

This skill is written for custom/headless storefronts (Node.js, Python, or similar backend). The code examples use TypeScript/Node.js and can be adapted to any stack.

Shopify: Shopify Hydrogen is Shopify's headless framework. MACH/composable patterns apply when using Shopify as the commerce backend with a custom frontend, or when mixing Shopify with other best-of-breed services. WooCommerce: WooCommerce can serve as a headless backend via its REST API and WPGraphQL. These patterns apply when decoupling the frontend from WordPress. Magento: Magento's GraphQL API and PWA Studio support headless architectures. These composable patterns apply to Magento as a backend service in a MACH stack.

You'll need:

Node.js 18+ (or adapt to your backend language)
Redis for caching/queues
An email sending service (SendGrid, AWS SES, or Postmark)
CDN (Cloudflare, CloudFront, or Fastly)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
