Overview of Shopify Hydrogen

{data.product.title} as part of the component output. Data Layer & API Integration Hydrogen relies on Shopify’s Storefront API for all data operations, accessed via useShopQuery for SSR or useQuery for client-side fetching. The framework enforces a GraphQL-first approach, ensuring efficient data retrieval. Example : A dynamic route fetching product details, including video metadata stored in metafields // Fetching product with video metafield const {data} = useShopQuery({ query: `query ProductWithVideo($handle: String!) { product(handle: $handle) { title metafield(namespace: 'media', key: 'video_url') { value } } }`, variables: {handle: params.handle}, }); Explanation : Defines the query ProductWithVideo , which takes a required handle as a variable. Queries the title of the product and a specific metafield with namespace 'media' and key 'video_url' . Accesses the value of the metafield, which contains the video URL. Passes the handle dynamically using variables: {handle: params.handle} . Getting Started Setup Initializing a Hydrogen project requires the Shopify CLI: npm init @shopify/hydrogen@latest cd my-hydrogen-store npm run dev The default template includes a /products route demonstrating SSR and hydration. Running npm run dev starts the Vite server with Hot Module Replacement (HMR) for rapid iteration. Embedding Videos in Shopify Hydrogen Handling Video Assets in Hydrogen Video content in Hydrogen often resides in Shopify metafields, retrievable via GraphQL. A product video can be rendered using the native

element. Wraps the ProductVideo component in a block with a fallback message shown while the video component loads. Lazy loading with Suspense prevents blocking the main thread, while autoplay logic can be controlled via React hooks. Performance Optimization for Video Storefronts Hydrogen’s streaming SSR reduces Largest Contentful Paint (LCP) by sending HTML chunks early. For video-heavy pages, preloading metadata and using adaptive streaming (e.g., HLS for mobile) ensures smooth playback. Oxygen’s edge caching stores video thumbnails globally, reducing latency: // Middleware for regional video quality export async function middleware(request) { const country = request.headers.get('cf-ipcountry'); const isMobile = request.headers.get('sec-ch-ua-mobile') === '?1'; const videoQuality = isMobile ? 'mobile_480p' : 'desktop_1080p'; return new Response(null, { headers: {'x-video-quality': videoQuality}, }); } Explanation : Detects if the request comes from a mobile device by checking if the sec-ch-ua-mobile header equals '?1' . Determines the appropriate video quality: assigns 'mobile_480p' for mobile users and 'desktop_1080p' for others. Returns a new HTTP response with an x-video-quality custom header set to the selected video quality value.
