Antigravity Agent 9a135bd19d docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동

최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치.
콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서
전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한
업데이트0615/무제 3.canvas 뿐).

Island Architecture

매 한 줄

"매 mostly-static HTML 의 sea 의 isolated interactive 'island' 의 selective hydration 의 통한 ship-less-JS". 매 Katie Sylor-Miller (2019) 의 term, Jason Miller (2020) 의 popularization, 매 Astro (2021) / Fresh (Deno) / Marko / Qwik 의 implementation — 매 SPA-everything 의 over-hydration 의 backlash.

매 핵심

매 핵심 idea

Server 의 HTML 의 render (default).
매 interactive component (island) 의 isolated hydration boundary.
매 island 의 own JS bundle, 매 nothing else 의 ship.
매 island 간 의 share state 의 X (or framework-specific signal).

매 Hydration directive (Astro)

client:load — 매 page load 의 즉시.
client:idle — requestIdleCallback.
client:visible — IntersectionObserver.
client:media="(min-width: 768px)" — viewport conditional.
client:only="react" — server render skip, client only.

매 응용

Content sites (blog, docs, marketing).
E-commerce (정적 product page + interactive cart island).
News / publishing (정적 article + comment island).

💻 패턴

Astro — React Island

---
// src/pages/index.astro
import Counter from '../components/Counter.tsx';
import Newsletter from '../components/Newsletter.tsx';
const posts = await fetch(import.meta.env.CMS_URL).then(r => r.json());
---
<html>
  <body>
    <h1>Blog</h1>
    <ul>{posts.map(p => <li>{p.title}</li>)}</ul>

    <Counter client:visible />               <!-- island, lazy hydrate -->
    <Newsletter client:idle />               <!-- island, idle hydrate -->
  </body>
</html>

Astro — Mixed Frameworks (one page, multiple)

---
import VueWidget from './Widget.vue';
import SvelteChart from './Chart.svelte';
import SolidSearch from './Search.tsx';
---
<VueWidget client:load />
<SvelteChart client:visible />
<SolidSearch client:idle />

Fresh (Deno) — Island

// islands/Counter.tsx
import { useSignal } from '@preact/signals';
export default function Counter() {
  const count = useSignal(0);
  return <button onClick={() => count.value++}>{count.value}</button>;
}

// routes/index.tsx
import Counter from '../islands/Counter.tsx';
export default function Home() {
  return <main><h1>Home</h1><Counter /></main>;
}

Qwik — Resumability (zero hydration)

// src/routes/index.tsx
import { component$, useSignal } from '@builder.io/qwik';
export default component$(() => {
  const count = useSignal(0);
  return (
    <button onClick$={() => count.value++}>
      Clicks: {count.value}
    </button>
  );
});
// 매 click 의 시 의 only 의 download — true progressive

Marko 5 — Streaming Islands

<!doctype html>
<html>
  <body>
    <h1>Products</h1>
    <await(productPromise)>
      <@then|products|>
        <for|p| of=products>
          <product-card p=p/>
        </for>
      </@then>
    </await>
  </body>
</html>

Performance Budget Check

# .lighthouserc.yml
ci:
  collect: { url: ['https://example.com/'] }
  assert:
    assertions:
      total-byte-weight: ['error', { maxNumericValue: 200000 }]
      total-blocking-time: ['error', { maxNumericValue: 200 }]
      interaction-to-next-paint: ['error', { maxNumericValue: 200 }]

매 결정 기준

상황	Approach
Content-heavy, low interactivity	Astro (default)
Per-route framework choice	Astro multi-framework
Edge / Deno preference	Fresh
App-shell SPA feel	Next.js / Remix (RSC + Suspense)
Zero-hydration target	Qwik

기본값: 매 marketing/blog/docs — Astro + island per interactive component. 매 dashboard-y app — Next.js RSC.

🔗 Graph

부모: Web-Rendering-Strategies · 프론트엔드 및 UIUX 표준
변형: Partial-Hydration · Resumability · Streaming SSR
응용: Astro · Qwik
Adjacent: React Server Components — 경계 의식 · Incremental-Static-Regeneration-ISR · MPA

🤖 LLM 활용

언제: page 의 island boundary 의 propose, hydration directive 의 select, JS bundle 의 reduction 의 suggest. 언제 X: 매 framework 의 final choice (team skill, ecosystem fit 의 human decision).

❌ 안티패턴

Island sprawl: 매 component 의 client:load → SPA equivalent.
Cross-island state: 매 island 의 shared store 의 hack — 매 framework boundary 의 violation.
Server-only data 의 island leak: secret/PII 의 client island prop 의 pass.
client:only overuse: server render 의 skip → SEO 의 hurt + LCP 의 regress.
Wrong tool: 매 highly interactive app (Figma-like) 의 Astro 의 force-fit.

🧪 검증 / 중복

Verified (Jason Miller "Islands Architecture" 2020, Astro 4 docs, Fresh docs, web.dev).
