Data Transformation Pipeline

Raw HTML → XPath Extraction → Post Processing → Goondex Models
     ↓               ↓                ↓              ↓
Scene Page → Title/Date/etc → Clean/Parse → Scene Struct
Performer Page → Name/Height/etc → Convert/Clean → Performer Struct

Configuration Integration

The scraper integrates with existing Goondex configuration:

# config/goondex.yml
scrapers:
  sugarinstant:
    enabled: true
    requiresBrowser: true
    rateLimit: 2s
    timeout: 30s
    siteConfig: {}

browser:
  enabled: true
  headless: true
  timeout: 30s
