# 콘텐츠 기반의 이커머스 및 뉴스 웹사이트 성능 튜닝

## 매 한 줄
> **"매 이커머스 와 뉴스 는 매 LCP 와 매 traffic spike 가 매 매출 / engagement 에 매 직결"**. 매 1 초 LCP 개선 = Amazon $1B/yr (고전), Pinterest +15% conversion. 매 2026 stack — Next.js 15 + ISR + Edge / CDN + Image optim — 가 매 default playbook.

## 매 핵심

### 매 두 도메인 의 차이
- **이커머스**: 매 product page 의 매 LCP (image), 매 PDP 의 매 INP (variant select), 매 cart 의 매 freshness.
- **뉴스**: 매 article 의 매 LCP (cover image / headline), 매 publishing speed (ISR ≤ 60s), 매 ad / tracker 부하.

### 매 핵심 lever
- **ISR (Incremental Static Regeneration)**: build-time SSG + runtime revalidate.
- **Edge caching**: Vercel / Cloudflare / Fastly 의 매 stale-while-revalidate.
- **Image CDN**: Cloudinary / imgix / Next Image — 매 AVIF + responsive.
- **Streaming SSR**: RSC + Suspense → 매 TTFB 개선.
- **Third-party tax 최소화**: GTM / pixel — 매 Partytown 또는 server-side tracking.

### 매 응용
1. Shopify Hydrogen / Next Commerce.
2. NYT, WaPo, Bloomberg 식 article.
3. Medium / Substack 식 long-tail.

## 💻 패턴

### ISR (Next 15)
```tsx
// app/products/[id]/page.tsx
export const revalidate = 60; // 매 60초 ISR

export default async function Product({ params }) {
  const product = await getProduct(params.id);
  return <ProductView product={product} />;
}

export async function generateStaticParams() {
  const top = await getTopProducts(1000); // 매 top 1000 prebuild
  return top.map(p => ({ id: p.id }));
}
```

### On-demand revalidation
```tsx
// app/api/revalidate/route.ts
import { revalidatePath } from "next/cache";

export async function POST(req: Request) {
  const { path, secret } = await req.json();
  if (secret !== process.env.REVALIDATE_SECRET) return new Response("nope", { status: 401 });
  revalidatePath(path);
  return Response.json({ revalidated: true });
}
```

### Streaming SSR (RSC + Suspense)
```tsx
export default function ArticlePage({ params }) {
  return (
    <>
      <ArticleHeader id={params.id} /> {/* 매 즉시 stream */}
      <Suspense fallback={<CommentsSkeleton />}>
        <Comments id={params.id} /> {/* 매 below-fold */}
      </Suspense>
    </>
  );
}
```

### Edge runtime (latency 최소)
```tsx
export const runtime = "edge";

export default async function Page() {
  const data = await fetch("https://api...", { next: { revalidate: 30 } });
  return <View data={await data.json()} />;
}
```

### Image responsive + priority
```tsx
<Image
  src={product.cover}
  alt={product.name}
  width={800} height={600}
  sizes="(max-width: 768px) 100vw, 50vw"
  priority={isAboveFold}
  quality={80}
/>
```

### Partytown (3rd-party off main thread)
```tsx
import Script from "next/script";

<Script src="https://www.googletagmanager.com/gtm.js?id=GTM-XXX"
        strategy="worker" />
```

### Cache header (CDN-friendly)
```tsx
return new Response(html, {
  headers: {
    "Cache-Control": "public, s-maxage=60, stale-while-revalidate=600",
  },
});
```

## 매 결정 기준
| 페이지 타입 | 전략 |
|---|---|
| Product Detail (top seller) | SSG + ISR(60s) + Edge |
| Product Detail (long tail) | SSR streaming |
| Cart / Checkout | SSR (no cache, fresh) |
| News article | SSG + ISR(30s) + on-demand |
| Live ticker | RSC + WebSocket |

**기본값**: **Next 15 App Router + ISR + Edge runtime + Next/Image + Partytown**.

- 변형: [[ISR]] · [[Edge Computing]] · [[Streaming SSR]]
- 응용: [[Shopify Hydrogen]] · [[Headless Commerce]]

## 🤖 LLM 활용
**언제**: 매 traffic-heavy content site, 매 PLP/PDP, 매 article-driven SEO.
**언제 X**: 매 internal admin, 매 auth-only SaaS.

## ❌ 안티패턴
- **Cart 까지 ISR**: 매 stale price → 매 trust 붕괴.
- **3rd-party 30+ scripts on main thread**: 매 INP 폭주.
- **Image 원본 그대로**: 매 5MB JPG → LCP 5초.
- **ISR revalidate 너무 짧음 (1s)**: 매 origin 부하.

## 🧪 검증 / 중복
- Verified (Vercel docs, web.dev case studies, Cloudflare Workers).
- 신뢰도 A.
