realtime

Overview ¶

Example: Real-time price monitor with webhook notifications

Demonstrates how to build a continuous price monitoring loop that:

• Sends price alerts via a webhook when prices change
• Deduplicates items by SKU so each product is only reported once per run
• Uses a Transform pipeline stage to compute price changes
• Shows the concept of periodic re-scraping using a ticker loop

This example targets books.toscrape.com as a safe public sandbox. In production you would substitute real product URLs and a real webhook endpoint (e.g., Slack, PagerDuty, or your own alerting service).

Run:

go run ./examples/realtime/
