# Chromium

## 매 한 줄
> **"매 Google 의 open-source browser engine codebase"**. 매 Blink (rendering, fork of WebKit, 2013) + V8 (JS) + Skia (graphics) + Mojo (IPC) 의 결합 — 매 2026 의 Chrome / Edge / Brave / Opera / Arc / Vivaldi / Electron / Tauri (WebView2) 의 base. 매 multi-process security architecture (sandbox, site isolation) 의 reference.

## 매 핵심

### 매 Architecture
- **Browser process**: 매 UI, network, disk — privileged.
- **Renderer process** (per site): 매 Blink + V8 — sandboxed.
- **GPU process**: Skia 의 hardware-accel.
- **Utility processes**: audio, network service.
- **Mojo IPC**: typed message passing.

### 매 Components
- **Blink**: HTML parse, CSS, layout, paint, compositor.
- **V8**: JS + WebAssembly (Sparkplug, Maglev, TurboFan, Liftoff).
- **Skia**: 2D graphics.
- **WebRTC, WebGPU, WebCodecs**: media.
- **Site Isolation**: 매 origin 의 process-level isolation — Spectre 의 mitigate.

### 매 응용
1. Chrome browser (1B+ users).
2. Embed: Electron, Tauri (WebView2 on Win), CEF.
3. Headless: Puppeteer, Playwright (chromium build).
4. Forks: Edge (2020+), Brave, Vivaldi, Arc, Opera.

## 💻 패턴

### Build chromium (sketch)
```bash
git clone https://chromium.googlesource.com/chromium/src.git
cd src
gclient sync
gn gen out/Release --args='is_debug=false'
autoninja -C out/Release chrome
```

### Headless via Puppeteer
```javascript
import puppeteer from "puppeteer";
const browser = await puppeteer.launch({ headless: "new", args: ["--no-sandbox"] });
const page = await browser.newPage();
await page.goto("https://example.com");
await page.screenshot({ path: "x.png" });
await browser.close();
```

### CDP (Chrome DevTools Protocol) raw
```javascript
const client = await page.target().createCDPSession();
await client.send("Performance.enable");
const metrics = await client.send("Performance.getMetrics");
```

### Site Isolation flag
```bash
chrome --site-per-process  # default since 2018
chrome --disable-site-isolation-trials  # debug only — never prod
```

### V8 inspect
```bash
node --inspect-brk app.js
# DevTools 의 chrome://inspect 의 attach
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| Build cross-platform desktop app | Tauri (smaller) > Electron (mature) |
| Web automation | Playwright > Puppeteer (multi-engine) |
| Custom browser | fork Chromium (Brave-style) — 매 maintenance cost 큼 |
| Embed web view | WebView2 (Win) / WKWebView (Mac) — 매 native > Electron |

**기본값**: 매 web app 의 Electron / Tauri 의 ship — 매 user-facing 의 자체 fork X.

## 🔗 Graph
- 변형: [[Chrome]] · [[Electron]]
- 응용: [[Playwright]]
- Adjacent: [[Blink]] · [[V8]] · [[WebKit]]

## 🤖 LLM 활용
**언제**: CDP 사용법, Puppeteer/Playwright script, Chromium component 의 explanation.
**언제 X**: 매 Chromium 의 internal C++ refactor — 매 LLM 의 outdated 가능.

## ❌ 안티패턴
- **--no-sandbox in production**: 매 sandboxing 의 disable — RCE 의 risk.
- **--disable-web-security**: 매 dev 만 — prod 의 catastrophic.
- **Pinning to old Chromium**: 매 CVE 의 backlog — 매 latest stable.
- **Electron + remote module**: 매 deprecated, 매 contextIsolation: true.

## 🧪 검증 / 중복
- Verified (chromium.org, source.chromium.org, V8 blog).
- 신뢰도 A.

## 🕓 Changelog
| 날짜 | 변경 |
|---|---|
| 2026-05-08 | Phase 1 |
