Hydrogen

Hydrogen is Shopify's React-based framework for building custom storefronts and headless e-commerce experiences with performance and developer experience as core priorities. The framework provides pre-built components, hooks, and utilities specifically designed for e-commerce use cases like product listings, cart management, checkout flows, and customer authentication. Hydrogen leverages Shopify's Storefront API to fetch product data, inventory, pricing, and customer information, providing a complete stack for building online stores. It includes server-side rendering capabilities, streaming architecture, and optimizations for Core Web Vitals to deliver fast, SEO-friendly storefronts. Hydrogen supports deployment to Oxygen (Shopify's hosting platform), Vercel, Netlify, or any platform that supports Node.js applications. The framework integrates deeply with Shopify's ecosystem including metafields, product variants, multi-currency, and internationalization features. Hydrogen enables developers to create highly customized shopping experiences while leveraging Shopify's robust e-commerce backend, combining flexibility with platform reliability.
