Environment Variables

Notification Format

When new content is found, the webhook receives:

{
  "feed": "Feed Name",
  "count": 3,
  "items": [
    {
      "title": "Article Title",
      "link": "https://example.com/article",
      "pubDate": "2024-01-15T10:30:00Z"
    }
  ]
}

Notes

• State is stored in ~/.feed-watcher/feeds.json
• Each feed tracks its own last-seen item
• Run scan before setting up cron to test feeds
• You can use with any notification service (Discord webhook, Telegram bot, Slack, etc.)
