HKIA Content Aggregation System

Project Overview

Complete content aggregation system that scrapes 6 sources (WordPress, MailChimp RSS, Podcast RSS, YouTube, Instagram, HVACRSchool), converts to markdown, and runs twice daily with incremental updates. TikTok scraper disabled due to technical issues.

Architecture

• Base Pattern: Abstract scraper class (BaseScraper) with common interface
• State Management: JSON-based incremental update tracking in data/.state/
• Parallel Processing: All 6 active sources run in parallel via ContentOrchestrator
• Output Format: hkia_[source]_[timestamp].md
• Archive System: Previous files archived to timestamped directories in data/markdown_archives/
• Media Downloads: Images/thumbnails saved to data/media/[source]/
• NAS Sync: Automated rsync to /mnt/nas/hkia/

Key Implementation Details

Instagram Scraper (src/instagram_scraper.py)

• Uses instaloader with session persistence
• Aggressive rate limiting: 15-30 second delays, extended breaks every 5 requests
• Session file: instagram_session_hkia1.session
• Authentication: Username hkia1, password I22W5YlbRl7x

TikTok Scraper ❌ DISABLED

• Status: Disabled in orchestrator due to technical issues
• Reason: GUI requirements incompatible with automated deployment
• Code: Still available in src/tiktok_scraper_advanced.py but not active

YouTube Scraper (src/youtube_hybrid_scraper.py)

• Hybrid Approach: YouTube Data API v3 for metadata + yt-dlp for transcripts
• Channel: @HVACKnowItAll (38,400+ subscribers, 447 videos)
• API Integration: Rich metadata extraction with efficient quota usage (3 units per video)
• Authentication: Firefox cookie extraction + PO token support via YouTubePOTokenHandler
• ❌ Transcript Status: DISABLED due to YouTube platform restrictions (Aug 2025)
  • Error: "The following content is not available on this app"
  • PO Token Implementation: Complete but blocked by YouTube platform restrictions
  • 179 videos identified with captions available but currently inaccessible
  • Will automatically resume transcript extraction when platform restrictions are lifted

RSS Scrapers

• MailChimp: https://us10.campaign-archive.com/feed?u=d1a98c3e62003104038942e21&id=2205dbf985
• Podcast: https://feeds.libsyn.com/568690/spotify

WordPress Scraper (src/wordpress_scraper.py)

• Direct API access to hvacknowitall.com
• Fetches blog posts with full content

HVACRSchool Scraper (src/hvacrschool_scraper.py)

• Web scraping of technical articles from hvacrschool.com
• Enhanced content cleaning with duplicate removal
• Handles complex HTML structures and embedded media

Technical Stack

• Python: 3.11+ with UV package manager
• Key Dependencies:
  • instaloader (Instagram)
  • scrapling[all] (TikTok anti-bot)
  • yt-dlp (YouTube)
  • feedparser (RSS)
  • markdownify (HTML conversion)
• Testing: pytest with comprehensive mocking

Deployment Strategy

✅ Production Setup - systemd Services

TikTok disabled - no longer requires GUI access or containerization restrictions.

# Service files location (✅ INSTALLED)
/etc/systemd/system/hkia-scraper.service
/etc/systemd/system/hkia-scraper.timer
/etc/systemd/system/hkia-scraper-nas.service  
/etc/systemd/system/hkia-scraper-nas.timer

# Working directory
/home/ben/dev/hvac-kia-content/

# Installation script
./install-hkia-services.sh

# Environment setup
export DISPLAY=:0
export XAUTHORITY="/run/user/1000/.mutter-Xwaylandauth.90WDB3"

Schedule (✅ ACTIVE)

• Main Scraping: 8:00 AM and 12:00 PM Atlantic Daylight Time (5 sources)
• NAS Sync: 8:30 AM and 12:30 PM (30 minutes after scraping)
• User: ben (GUI environment available but not required)

Environment Variables

# Required in /opt/hvac-kia-content/.env
INSTAGRAM_USERNAME=hkia1
INSTAGRAM_PASSWORD=I22W5YlbRl7x
YOUTUBE_CHANNEL=@hkia
TIKTOK_USERNAME=hkia
NAS_PATH=/mnt/nas/hkia
TIMEZONE=America/Halifax

Commands

Development Setup

# Install UV package manager (if not installed)
pip install uv

# Install dependencies 
uv sync

# Install Python dependencies
uv pip install -r requirements.txt

Testing

# Test individual sources
uv run python test_real_data.py --source [youtube|instagram|tiktok|wordpress|mailchimp|podcast]

# Test backlog processing  
uv run python test_real_data.py --type backlog --items 50

# Test cumulative markdown system
uv run python test_cumulative_mode.py

# Full test suite
uv run pytest tests/ -v

# Test specific scraper with detailed output
uv run pytest tests/test_[scraper_name].py -v -s

# Test with specific GUI environment for TikTok
DISPLAY=:0 XAUTHORITY="/run/user/1000/.mutter-Xwaylandauth.90WDB3" uv run python test_real_data.py --source tiktok

# Test YouTube transcript extraction (currently blocked by YouTube)
DISPLAY=:0 XAUTHORITY="/run/user/1000/.mutter-Xwaylandauth.90WDB3" uv run python youtube_backlog_all_with_transcripts.py

Production Operations

# Service management (✅ ACTIVE SERVICES)
sudo systemctl status hkia-scraper.timer
sudo systemctl status hkia-scraper-nas.timer
sudo journalctl -f -u hkia-scraper.service
sudo journalctl -f -u hkia-scraper-nas.service

# Manual runs (for testing)
uv run python run_production_with_images.py
uv run python -m src.orchestrator --sources youtube instagram
uv run python -m src.orchestrator --nas-only

# Legacy commands (still work)
uv run python -m src.orchestrator
uv run python run_production_cumulative.py

# Debug and monitoring
tail -f logs/[source]/[source].log
ls -la data/markdown_current/
ls -la data/media/[source]/

Critical Notes

1. ✅ TikTok Scraper: DISABLED - No longer blocks deployment or requires GUI access
2. Instagram Rate Limiting: 100 requests/hour with exponential backoff
3. YouTube Transcript Status: DISABLED in production due to platform restrictions (Aug 2025)
   • Complete PO token implementation but blocked by YouTube platform changes
   • 179 videos identified with captions but currently inaccessible
   • Hybrid scraper architecture ready to resume when restrictions are lifted
4. State Files: Located in data/.state/ directory for incremental updates
5. Archive Management: Previous files automatically moved to timestamped archives in data/markdown_archives/[source]/
6. Media Management: Images/videos saved to data/media/[source]/ with consistent naming
7. Error Recovery: All scrapers handle rate limits and network failures gracefully
8. ✅ Production Services: Fully automated with systemd timers running twice daily
9. Package Management: Uses UV for fast Python package management (uv run, uv sync)

YouTube Transcript Status (August 2025)

Current Status: ❌ DISABLED - Transcripts extraction disabled in production

Implementation Status:

• ✅ Hybrid Scraper: Complete (src/youtube_hybrid_scraper.py)
• ✅ PO Token Handler: Full implementation with environment variable support
• ✅ Firefox Integration: Cookie extraction and profile detection working
• ✅ API Integration: YouTube Data API v3 for efficient metadata extraction
• ❌ Transcript Extraction: Disabled due to YouTube platform restrictions

Technical Details:

• 179 videos identified with captions available but currently inaccessible
• PO Token: Extracted and configured (YOUTUBE_PO_TOKEN_MWEB_GVS in .env)
• Authentication: Firefox cookies (147 extracted) + PO token support
• Platform Error: "The following content is not available on this app"

Architecture: True hybrid approach maintains efficiency:

• Metadata: YouTube Data API v3 (cheap, reliable, rich data)
• Transcripts: yt-dlp with authentication (currently blocked)
• Fallback: Gracefully continues without transcripts

Future: Will automatically resume transcript extraction when platform restrictions are resolved.
