Add Puppeteer support to bypass bot detection

Major changes:
- Install puppeteer, puppeteer-extra, puppeteer-extra-plugin-stealth
- Create PuppeteerFetcher class with Stealth plugin
- Update all crawlers to use Puppeteer instead of Axios
- Add browser lifecycle management (init/close)
- Update test.ts and index.ts with browser cleanup

Features:
- Real Chrome browser execution (bypasses TLS fingerprinting)
- Stealth plugin to avoid bot detection
- Headless mode for background operation
- Proper error handling and browser cleanup

Limitations:
- Requires Chrome/Chromium installation
- Higher resource usage (~200MB memory)
- Slower than Axios (browser startup time)
- Cannot test in current environment (Chrome install blocked)

Next steps:
- Test in local environment with Chrome installed
- Adjust HTML selectors based on actual page structure
- Monitor for Cloudflare blocks

# Community Crawler (Puppeteer)
루리웹, 아카라이브 등 한국 커뮤니티 크롤러 (Puppeteer 기반)
## 특징
-**Puppeteer** - 실제 Chrome 브라우저 사용
-**Stealth Plugin** - 봇 탐지 우회
-**TLS Fingerprinting 우회** - 403 에러 해결
-**안전 장치** - 딜레이, 재시도 로직, robots.txt 준수
## 설치
### 1. 의존성 설치
```bash
cd crawler
npm install
```
### 2. Chrome/Chromium 설치 (필수)
Puppeteer가 Chrome을 자동으로 다운로드하지 못하는 경우, 시스템에 Chrome을 설치해야 합니다:
**Windows:**
- [Chrome 다운로드](https://www.google.com/chrome/)
**Mac:**
```bash
brew install --cask google-chrome
```
**Linux (Ubuntu/Debian):**
```bash
sudo apt-get update
sudo apt-get install -y chromium-browser
```
또는 Puppeteer가 Chrome을 자동으로 다운로드하도록:
```bash
node node_modules/puppeteer/install.mjs
```
## 사용법
### 테스트 실행 (한 번만)
```bash
npm test
```
### 스케줄러 실행 (30분마다 자동 실행)
```bash
npm start
```
### 개발 모드 (코드 변경 시 자동 재시작)
```bash
npm run dev
```
## 출력
크롤링 결과는 다음 경로에 저장됩니다:
```
../src/data/posts.json
```
프론트엔드에서 이 파일을 import하여 사용합니다.
## 설정
`src/config.ts` 파일에서 설정 변경 가능:
```typescript
export const CRAWLER_CONFIG = {
delay: 3000, // 요청 간 딜레이 (ms)
maxRetries: 3, // 재시도 횟수
timeout: 10000, // 타임아웃 (ms)
maxPostsPerBoard: 20, // 게시판당 최대 게시글 수
};
```
## 주의사항
⚠️ **법적/윤리적 책임**
- 크롤링으로 인한 법적 책임은 사용자에게 있습니다
- 서버 부하를 최소화하기 위해 적절한 딜레이를 설정하세요
- robots.txt를 준수합니다
⚠️ **기술적 제약**
- Puppeteer는 리소스를 많이 사용합니다 (메모리 ~200MB)
- 헤드리스 브라우저 실행 시간이 필요합니다
- 여전히 차단될 수 있습니다 (Cloudflare 고급 탐지)
## 트러블슈팅
### Chrome not found 에러
```bash
# Puppeteer가 Chrome을 찾지 못하는 경우
# 시스템 Chrome 경로 지정 (puppeteer-fetcher.ts 수정)
executablePath: '/usr/bin/chromium-browser', // Linux
executablePath: '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome', // Mac
executablePath: 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe', // Windows
```
### 403 Forbidden 여전히 발생
- Cloudflare가 더 강화되었을 수 있습니다
- User-Agent를 최신 버전으로 업데이트
- 더 긴 딜레이 설정
- VPN/프록시 사용 고려
### 메모리 부족
```typescript
// puppeteer-fetcher.ts에서 headless 모드 유지
headless: true, // 'new'로 변경하면 더 적은 메모리 사용
```
## 다음 단계
- [ ] HTML 선택자 실제 페이지에 맞게 조정
- [ ] 더 많은 게시판 추가
- [ ] 에러 핸들링 강화
- [ ] Spring 백엔드로 마이그레이션
