What Hydrogen Actually Changes — And What Stays Intact

Your storefront renders on Shopify's edge the moment a request lands. Hydrogen replaces your Liquid theme with a React + Remix architecture that talks directly to the Storefront API — no theme engine, no section schema constraints, no reloads between page transitions. Your product catalog, cart logic, and checkout flow remain in Shopify. Your metafields, metaobjects, and Markets config stay untouched. What changes is rendering speed (sub-second), composability (real React components), and control (every pixel, every animation, every data fetch is yours). Your SEO equity transfers through 1:1 URL mapping and preserved structured data. The risk isn't technical — it's losing ranking momentum or breaking attribution if the handoff isn't executed with surgical precision.

Où les projets échouent

Liquid themes regularly hit 4+ second load times on mobile Every extra second drops conversion rates by roughly 7%—and that compounds into real revenue loss every single month.
Online Store 2.0 section schema limits what you can actually build Your design team mocks up features your theme simply can't implement, and everyone wastes time on workarounds that still underperform.
Third-party Liquid apps inject JavaScript and CSS you can't control Each new app adds 200–500KB of payload you can't tree-shake, and your Core Web Vitals scores quietly get worse with every addition.
There's no real SPA navigation—every click triggers a full page reload Shoppers bail on browse sessions because the experience feels sluggish compared to competitors running headless stacks.
Cart and checkout customization is locked down by Shopify's Liquid constraints Custom upsells, dynamic bundles, branded checkout flows—none of it's possible, and all of it directly affects AOV.
SEO equity is at risk if URLs, canonicals, and structured data aren't handled precisely during migration Losing indexed URLs and backlink authority can hammer organic traffic for months after launch.

Conformité

Storefront API Integration

Every data fetch runs through Shopify's Storefront API via GraphQL. Type-safe queries keep your product, collection, and cart data consistent with your Shopify admin.

Full Redirect Mapping

We audit every indexed Liquid URL and build a complete redirect map before cutover. No orphaned pages, no 404s, no lost link equity.

Cart & Checkout Continuity

Cart state moves to Hydrogen's cart API with persistent sessions. Checkout hands off to Shopify's hosted checkout or Checkout Extensibility, depending on your plan.

Structured Data Preservation

Product, breadcrumb, and organization schema get rebuilt in React components with JSON-LD. We validate every template against Google's Rich Results Test before launch.

Oxygen Edge Deployment

Your Hydrogen storefront deploys to Shopify Oxygen with automatic edge caching, cache invalidation on publish, and zero DevOps overhead on your end.

Performance Budgets

We set hard performance budgets per route—LCP under 1.2s, CLS under 0.05, TBT under 150ms. CI checks block any deploy that regresses these targets.

Ce que nous construisons

Liquid sections hit 4+ second mobile loads — every extra second bleeds 7% of your conversion rate

Sub-second page renders with Oxygen edge hosting and server-side React — your buyers feel the speed immediately

Section schema locks you into rigid layouts your design team mocks up but can't actually ship

Full React component library with typed props replaces Liquid sections — design becomes code without compromise

Third-party apps inject uncontrollable JavaScript that quietly destroys your Core Web Vitals scores

Tree-shaken bundles and zero third-party bloat — you control every kilobyte that ships to the browser

Full page reloads on every click make your store feel slower than headless competitors

Instant SPA navigation with Remix routing — browse sessions feel native, not web-clunky

Cart and checkout customization is blocked by Liquid constraints — killing upsell and bundle opportunities

Custom cart drawers, dynamic upsells, and branded flows built in React — your AOV logic finally ships

Mishandled URL migration or broken canonicals can hammer your organic traffic for six months post-launch

1:1 URL preservation, canonical integrity, and structured data continuity — your rankings and backlinks transfer intact

Questions fréquentes

Combien de temps dure une migration Shopify Liquid vers Hydrogen ?

La plupart des migrations prennent 4 à 8 semaines, selon la complexité du thème, les sections personnalisées, les intégrations d'applications et les exigences d'internationalisation. Un thème standard basé sur Dawn avec une personnalisation modérée atterrit généralement autour de 5 à 6 semaines. Les thèmes fortement modifiés avec 20+ sections personnalisées et plusieurs dépendances d'applications tierces se rapprochent de 8 semaines.

Vais-je perdre mes classements SEO lors de la migration ?

Non, si les redirections et les canoniques sont correctement gérés. Nous construisons une carte de redirection d'URL complète avant le basculement, préservons toutes les données structurées dans les composants React et validons chaque route avec les outils d'indexation de Google. Après le lancement, nous surveillons la Search Console pour les erreurs d'exploration quotidiennement pendant 30 jours.

Ai-je besoin de Shopify Plus pour Hydrogen ?

Non. Hydrogen fonctionne avec n'importe quel plan Shopify via l'API Storefront. Cela dit, Shopify Plus déverrouille Checkout Extensibility, ce qui vous donne plus de contrôle sur l'interface de paiement. Si les flux de paiement personnalisés sont importants pour votre entreprise, Plus vaut la peine d'être envisagé. L'hébergement Oxygen est disponible sur tous les plans.

Qu'advient-il de mes applications Shopify après la migration ?

Les intégrations d'applications Liquid ne fonctionnent pas dans Hydrogen. Nous auditons chaque application, déterminons ce qui doit être reconstruit en natif dans React et identifions ce qui peut être remplacé par des intégrations au niveau de l'API. Les applications d'avis, de programmes de fidélité et d'abonnement avec des API s'intègrent généralement sans trop de friction. Les applications qui injectent uniquement des snippets Liquid doivent être remplacées.

Puis-je continuer à utiliser l'éditeur de thème Shopify avec Hydrogen ?

Hydrogen n'utilise pas l'éditeur de thème Online Store. La gestion du contenu bascule vers l'administrateur Shopify pour les produits et les collections, tandis que le contenu des pages personnalisées peut être géré via des métaobjets ou un CMS headless comme Sanity. Nous cartographions le flux de travail d'édition du contenu au cours de la phase d'audit afin que votre équipe sache exactement à quoi s'attendre.

Comment les performances de Hydrogen se comparent-elles aux thèmes Liquid ?

Les vitrines Hydrogen sur Oxygen atteignent généralement une LCP sub-1-seconde, comparé à 3 à 5 secondes sur les thèmes Liquid. Cet écart provient du rendu côté serveur à la périphérie, de l'absence de surcharge du framework de thème, des bundles JavaScript arborescents et de la suppression du poids des applications tierces. En pratique, la plupart des boutiques constatent des chargements de pages 50 à 70 % plus rapides.
