What Is a Shopify Liquid to Hydrogen Migration?

A Liquid to Hydrogen migration replaces your Shopify Online Store 2.0 theme—built with Liquid templating—with a Hydrogen storefront powered by React and Remix. Hydrogen talks to Shopify through the Storefront API, which hands you full control over rendering, routing, and UX while deploying to Shopify's Oxygen edge hosting. The result is a server-rendered React storefront with sub-second page loads and none of the constraints that come with themes.

プロジェクトが失敗する理由

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.

コンプライアンス

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.

構築する内容

Liquid Section → React Component Mapping

Every Liquid section and block gets a corresponding React component with typed props, preserving your content model while unlocking composability.

Metafield & Metaobject Support

Custom metafields and metaobjects query through the Storefront API so your enriched product data renders exactly as designed in Hydrogen.

Dynamic Collection Filtering

Faceted filtering is built with Shopify's filter API—server-rendered for SEO, with instant client-side updates for UX.

Internationalization Ready

Multi-language and multi-currency support runs through Shopify Markets, with locale-aware routing built into Remix.

Custom Cart Drawer & Upsells

A React-powered slide-out cart with real-time inventory checks, dynamic upsell logic, and animated transitions. None of this is doable natively in Liquid.

Analytics & Pixel Continuity

Shopify Analytics, Google Analytics 4, and conversion pixels get re-implemented through Hydrogen's analytics hooks so attribution stays intact throughout the migration.

よくある質問

Shopify LiquidからHydrogenへの移行にはどのくらい時間がかかりますか?

ほとんどの移行は4~8週間で完了します。テーマの複雑さ、カスタムセクション、アプリ連携、多言語対応の要件によって異なります。標準的なDawnベースのテーマで中程度のカスタマイズであれば、通常5~6週間です。20個以上のカスタムセクションと複数のサードパーティアプリ依存がある大幅にカスタマイズされたテーマは、8週間近くかかる可能性があります。

移行中にSEOランキングを失いますか?

リダイレクトと正規URLが適切に処理されていれば失いません。カットオーバー前に完全なURLリダイレクトマップを構築し、Reactコンポーネント内のすべての構造化データを保持し、Googleのインデックス作成ツールに対してすべてのルートを検証します。ローンチ後、30日間毎日Search Consoleのクローエラーを監視します。

HydrogenにはShopify Plusが必要ですか?

いいえ。HydrogenはStorefront APIを通じて任意のShopifyプランで動作します。ただし、Shopify Plusはチェックアウト拡張機能をロック解除し、チェックアウトUIをより詳細に制御できます。カスタムチェックアウトフローがビジネスにとって重要な場合、Plusを検討する価値があります。Oxygenホスティングはすべてのプランで利用可能です。

移行後、Shopifyアプリはどうなりますか?

LiquidアプリエンベッドはHydrogenでは機能しません。すべてのアプリを監査し、Reactでネイティブに再構築する必要があるものを特定し、APIレベルの統合に置き換えられるものを特定します。レビュー、ロイヤルティプログラム、APIを備えたサブスクリプションアプリは通常、スムーズに統合できます。Liquidスニペットのみを挿入するアプリは置き換える必要があります。

HydrogenでShopifyのテーマエディタを使い続けられますか?

HydrogenはOnline Storeテーマエディタを使用しません。コンテンツ管理は製品とコレクションについてはShopify adminに移行し、カスタムページコンテンツはメタオブジェクトまたはSanityなどのヘッドレスCMSで処理できます。監査フェーズ中にコンテンツ編集ワークフローをマッピングするため、チームは何が期待されるかを正確に理解できます。

HydrogenのパフォーマンスはLiquidテーマと比べてどうですか?

Oxygen上のHydrogenストアフロントは通常、サブ1秒のLCPに達します。一方、Liquidテーマは3~5秒です。このギャップはエッジでのサーバーサイドレンダリング、テーマフレームワークオーバーヘッドの削除、ツリーシェイク済みJavaScriptバンドル、サードパーティアプリのブロートウェアの削除から生じます。実際には、ほとんどのストアは50~70%高速なページ読み込みを実現します。
