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.

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.

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

よくある質問

Shopify Liquid to Hydrogen の移行にはどのくらいの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、アプリ統合、多言語化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の場合、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関係を持つ大幅に変更されたテーマは、8 週間に近くなります。

移行中に SEO ランキングを失いますか?

リダイレクトとカノニカルが正しく処理されていれば、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、すべての構造化データを React コンポーネントで保持し、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。起動後、30 日間毎日 Search Console でクロール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 を通じてすべての Shopify プランで機能します。ただし、Shopify Plus は Checkout Extensibility をアンロックするため、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。

移行後の Shopify アプリはどうなりますか?

Liquid アプリ埋め込みは Hydrogen では機能しません。すべてのアプリを監査し、React ネイティブで再構築する必要があるものを特定し、API レベルの統合で置き換えられるものを識別します。API を持つレビュー、ロイヤルティプログラム、サブスクリプションアプリは通常、摩擦なく統合されます。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用し続けることはできますか?

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 の管理画面にシフトし、カスタムページコンテンツは metaobjects またはSanity などのヘッドレス CMS で処理できます。監査フェーズでコンテンツ編集ワークフローをマップアップするため、チームは何が期待されるかを正確に知ることができます。

Hydrogen のパフォーマンスと Liquid テーマはどう比較されますか?

Oxygen 上の Hydrogen ストアフロントは通常、サブ 1 秒の LCP を達成しますが、Liquid テーマでは 3～5 秒です。この差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のオーバーヘッドなし、tree-shaken JavaScript バンドル、サードパーティアプリのブロートウェア削除から生じます。実際には、ほとんどのストアは 50～70% より高速なページロードを実現しています。
