# SPA (Single Page Application)
|
||||
|
||||
## 매 한 줄
|
||||
> **"매 single HTML shell 의 의 client-side routing + dynamic rendering 의 driven 의 web app 의 architecture."**. 매 2010s 의 의 dominant pattern (AngularJS, Backbone, Ember → React, Vue, Angular), 매 2026 의 RSC / SSR / Islands 의 ascendency 의 의 SPA 의 niche 화 — 매 highly-interactive dashboards, internal tools, complex stateful UIs 의 의 the right tool 이며 marketing/content 의 의 의 SSG/SSR 의 권장.
|
||||
|
||||
## 매 핵심
|
||||
|
||||
### 매 정의
|
||||
- 1 HTML document 의 load — subsequent navigation 의 JS 의 driven (no full page reload).
|
||||
- Client-side router 의 URL ↔ component tree 의 mapping.
|
||||
- Data 의 fetch via XHR/Fetch — JSON API or RPC.
|
||||
- State 의 client 의 in-memory (Redux, Zustand, Jotai, TanStack Query).
|
||||
|
||||
### 매 trade-offs
|
||||
- **Pros**: snappy in-app navigation, rich interactivity, app-like UX, shared state across views.
|
||||
- **Cons**: SEO 의 weak (without SSR), initial bundle 의 large, white screen 의 risk, accessibility 의 careful 의 wiring.
|
||||
|
||||
### 매 vs. modern alternatives
|
||||
- **SSR / SSG (Next.js, Remix)**: server 의 HTML 의 generate, hydration 의 client interactivity 의 add.
|
||||
- **RSC (React Server Components, 2026 mainstream)**: server-only components + client islands.
|
||||
- **Islands (Astro, Fresh, 11ty)**: static HTML + targeted hydration 의 islands.
|
||||
- **MPA (Multi-Page App)**: traditional server-rendered pages — Hotwire / Inertia 의 의 modern revival.
|
||||
|
||||
### 매 응용
|
||||
1. Internal admin dashboards (high interactivity, no SEO need).
|
||||
2. Authenticated SaaS apps (Linear, Figma, Notion).
|
||||
3. Real-time collaboration (CRDT-driven, websocket-heavy).
|
||||
4. Browser-based tools (Excalidraw, Tldraw).
|
||||
|
||||
## 💻 패턴
|
||||
|
||||
### React Router (data router, 2026)
|
||||
```tsx
|
||||
import { createBrowserRouter, RouterProvider } from 'react-router';
|
||||
|
||||
const router = createBrowserRouter([
|
||||
{
|
||||
path: '/',
|
||||
Component: Layout,
|
||||
children: [
|
||||
{ index: true, Component: Home },
|
||||
{ path: 'projects/:id', Component: Project, loader: projectLoader },
|
||||
{ path: '*', Component: NotFound },
|
||||
],
|
||||
},
|
||||
]);
|
||||
|
||||
export const App = () => <RouterProvider router={router} />;
|
||||
```
|
||||
|
||||
### Data fetching (TanStack Query)
|
||||
```tsx
|
||||
import { useQuery } from '@tanstack/react-query';
|
||||
|
||||
export function ProjectView({ id }: { id: string }) {
|
||||
const { data, isPending, error } = useQuery({
|
||||
queryKey: ['project', id],
|
||||
queryFn: () => fetch(`/api/projects/${id}`).then((r) => r.json()),
|
||||
staleTime: 60_000,
|
||||
});
|
||||
if (isPending) return <Skeleton />;
|
||||
if (error) return <ErrorBoundary error={error} />;
|
||||
return <ProjectDetail project={data} />;
|
||||
}
|
||||
```
|
||||
|
||||
### Client state (Zustand)
|
||||
```ts
|
||||
import { create } from 'zustand';
|
||||
import { persist } from 'zustand/middleware';
|
||||
|
||||
export const useUIStore = create(
|
||||
persist<{ sidebar: boolean; toggle: () => void }>(
|
||||
(set) => ({
|
||||
sidebar: true,
|
||||
toggle: () => set((s) => ({ sidebar: !s.sidebar })),
|
||||
}),
|
||||
{ name: 'ui-store' },
|
||||
),
|
||||
);
|
||||
```
|
||||
|
||||
### Code splitting (lazy routes)
|
||||
```tsx
|
||||
import { lazy, Suspense } from 'react';
|
||||
|
||||
const Settings = lazy(() => import('./routes/Settings'));
|
||||
|
||||
const router = createBrowserRouter([
|
||||
{
|
||||
path: '/settings',
|
||||
element: (
|
||||
<Suspense fallback={<RouteSkeleton />}>
|
||||
<Settings />
|
||||
</Suspense>
|
||||
),
|
||||
},
|
||||
]);
|
||||
```
|
||||
|
||||
### History API (without router)
|
||||
```ts
|
||||
window.history.pushState({}, '', '/projects/42');
|
||||
window.dispatchEvent(new PopStateEvent('popstate'));
|
||||
window.addEventListener('popstate', () => {
|
||||
render(parseRoute(location.pathname));
|
||||
});
|
||||
```
|
||||
|
||||
### Auth guard (route loader)
|
||||
```tsx
|
||||
async function projectLoader({ params }: LoaderFunctionArgs) {
|
||||
const session = await getSession();
|
||||
if (!session) throw redirect('/login');
|
||||
return fetch(`/api/projects/${params.id}`).then((r) => r.json());
|
||||
}
|
||||
```
|
||||
|
||||
### Vite SPA의 setup
|
||||
```ts
|
||||
// vite.config.ts
|
||||
import { defineConfig } from 'vite';
|
||||
import react from '@vitejs/plugin-react';
|
||||
|
||||
export default defineConfig({
|
||||
plugins: [react()],
|
||||
build: { sourcemap: true, target: 'es2022' },
|
||||
server: { historyApiFallback: true },
|
||||
});
|
||||
```
|
||||
|
||||
### SEO 의 fallback (prerender + hydrate)
|
||||
```ts
|
||||
// vite-plugin-prerender
|
||||
import prerender from 'vite-plugin-prerender';
|
||||
|
||||
export default {
|
||||
plugins: [
|
||||
react(),
|
||||
prerender({ routes: ['/', '/about', '/pricing'] }),
|
||||
],
|
||||
};
|
||||
```
|
||||
|
||||
## 매 결정 기준
|
||||
| 상황 | Approach |
|
||||
|---|---|
|
||||
| Marketing site, blog | **SSG** (Astro, Next.js static, 11ty) |
|
||||
| Content site with personalization | **SSR** (Next.js, Remix) |
|
||||
| Dashboards, admin tools | **SPA** (React Router + Vite) |
|
||||
| Highly interactive editor | **SPA** with code-splitting |
|
||||
| Public app needing SEO + interactivity | **Next.js (RSC + client islands)** |
|
||||
| MPA-style with sprinkles | **Hotwire / Inertia.js** |
|
||||
|
||||
**기본값**: 2026 의 default 는 **Next.js / Remix (SSR + RSC)** — pure SPA 는 internal tools / authenticated apps 의 으로 의 reserve.
|
||||
|

## 🔗 Graph
|
||||
- 부모: [[프론트엔드_및_UIUX_표준|Frontend-Architecture]]
|
||||
- 변형: [[SSR]] · [[SSG]] · [[Islands-Architecture]] · [[React-Server-Components]]
|
||||
- Adjacent: [[Vite]] · [[Code-Splitting]]
|
||||
|
||||
## 🤖 LLM 활용
|
||||
**언제**: highly-interactive authenticated app, no SEO requirement, complex client state, real-time collaboration.
|
||||
**언제 X**: marketing/content site (SSG), public SEO-critical content (SSR/RSC), simple form-driven app (MPA).
|
||||
|
||||
## 안티패턴
|
||||
- **SPA 의 marketing site**: SEO 의 weak, LCP 의 poor — SSG 의 사용.
|
||||
- **Bundle 의 single chunk**: route-based code splitting 의 default.
|
||||
- **Auth state 의 localStorage 의 raw token**: HttpOnly cookie + refresh flow 의 사용.
|
||||
- **Client routing 의 server fallback 없음**: 404 의 deep link 의 — `historyApiFallback` / catch-all rewrite.
|
||||
- **No skeleton / suspense**: white screen on slow data — Suspense + skeletons.
|
||||
- **Global state 의 overuse**: server state 의 TanStack Query, UI state 의 Zustand/Jotai 의 separate.
|
||||
|
||||
## 🧪 검증 / 중복
|
||||
- Verified (React Router 7 docs, Vue Router 4, MDN SPA architecture, web.dev rendering patterns 2026).
|
||||
- 신뢰도 A.
