# 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
|
|
1. Content sites (blog, docs, marketing).
|
|
2. E-commerce (정적 product page + interactive cart island).
|
|
3. News / publishing (정적 article + comment island).
|
|
|
|
## 💻 패턴
|
|
|
|
### Astro — React Island
|
|
```astro
|
|
---
|
|
// 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)
|
|
```astro
|
|
---
|
|
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
|
|
```tsx
|
|
// 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)
|
|
```tsx
|
|
// 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
|
|
```marko
|
|
<!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
|
|
```yaml
|
|
# .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.

## 🤖 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).
|
|
- 신뢰도 A.
