Blink

매 한 줄

"매 Chromium 의 rendering engine — 매 Web 의 de facto standard.". Blink 는 Google 이 2013 년 WebKit 에서 fork 한 layout/rendering engine 으로, Chrome/Edge/Brave/Opera 등 Chromium-based browser 의 90%+ market share 를 통해 매 modern web platform (CSS Grid, Houdini, View Transitions) 을 정의한다.

매 핵심

매 Pipeline

1. Parse — HTML/CSS → DOM/CSSOM.
2. Style — selector matching, computed style.
3. Layout (LayoutNG) — box tree, fragment tree.
4. Paint — display item list.
5. Composite (CC) — layer tree → GPU draw quads.
6. Raster + Display — Skia/SkiaGanesh → Viz → Display compositor.

매 vs WebKit / Gecko

• Blink (Chromium): V8, Skia, multi-process.
• WebKit (Safari): JavaScriptCore, CoreGraphics/Metal.
• Gecko (Firefox): SpiderMonkey, WebRender (Rust).

매 응용

1. Chrome/Edge browsers.
2. Electron/Tauri (Tauri uses platform webview).
3. CEF (Chromium Embedded Framework).
4. Headless Chrome / Puppeteer / Playwright.

💻 패턴

Custom Element via Web Components

class MyButton extends HTMLElement {
  connectedCallback() {
    this.attachShadow({ mode: "open" }).innerHTML = `
      <button><slot></slot></button>
      <style>button { padding: 8px 16px; }</style>`;
  }
}
customElements.define("my-button", MyButton);

CSS Houdini Paint Worklet

// checkerboard.js
class Checkerboard {
  paint(ctx, geom, props) {
    const size = props.get("--check-size").value;
    for (let y = 0; y < geom.height; y += size)
      for (let x = 0; x < geom.width; x += size)
        if (((x/size) + (y/size)) % 2) ctx.fillRect(x, y, size, size);
  }
}
registerPaint("checkerboard", Checkerboard);

div { background: paint(checkerboard); --check-size: 20; }

View Transitions (Blink 111+)

async function navigate(url) {
  if (!document.startViewTransition) return location.assign(url);
  const t = document.startViewTransition(() => loadInto(url));
  await t.finished;
}

Performance: Containment

.card {
  contain: layout paint style;  /* isolate subtree work */
  content-visibility: auto;     /* skip offscreen rendering */
}

DevTools Trace (Programmatic)

// puppeteer
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.tracing.start({ path: "trace.json", categories: ["devtools.timeline"] });
await page.goto("https://example.com");
await page.tracing.stop();

CDP (Chrome DevTools Protocol)

const client = await page.target().createCDPSession();
await client.send("Performance.enable");
const { metrics } = await client.send("Performance.getMetrics");
console.log(metrics.find(m => m.name === "LayoutCount"));

매 결정 기준

상황	권장
Cross-browser web app	Standards-only, test 3 engines
Desktop app (full Chromium)	Electron/CEF
Lightweight desktop	Tauri (system webview)
Automation/scrape	Playwright (multi-engine)
Mobile WebView	System WebView (avoid bundling)

기본값: standards + feature detection; Blink-specific API only with fallbacks.

🔗 Graph

• 부모: Chromium
• 변형: WebKit
• 응용: Electron · Playwright
• Adjacent: V8 · Skia

🤖 LLM 활용

언제: explain pipeline stage, generate web platform boilerplate. 언제 X: Blink internals C++ patches — need source + CL review.

❌ 안티패턴

• Vendor-prefixed only: -webkit- without standard fallback.
• Layout thrashing: read-write-read forced sync layouts.
• Heavy main thread: blocks composite — use Workers + OffscreenCanvas.
• Assuming Chromium-only: breaks Safari/Firefox parity.

🧪 검증 / 중복

• Verified (chromium.org docs, web.dev, Blink design docs).
• 신뢰도 A.
