Automated Hacker News Monitoring and Alerting
detail.loadingPreview
This n8n workflow automates the monitoring of Hacker News for content changes. It periodically fetches content, waits, fetches again, and triggers an alert via Telegram if any changes are detected.
About This Workflow
Leverage this powerful n8n workflow to stay on top of the latest discussions on Hacker News without manual intervention. The automation begins with a scheduled trigger, fetching the current Hacker News homepage content. After a brief pause to ensure a fresh perspective, it retrieves the content again. A sophisticated IF node then compares the two fetched versions. If any discrepancy is found, indicating new content or changes, an immediate alert is sent to a designated Telegram chat, keeping you informed of the rapidly evolving tech landscape.
Key Features
- Scheduled Monitoring: Automatically fetches Hacker News content at customizable intervals.
- Change Detection: Compares content between fetches to identify updates.
- Real-time Alerts: Notifies you via Telegram when changes are detected.
- Configurable Intervals: Easily adjust the monitoring frequency.
- Robust Error Handling: Built-in logic to manage potential fetching issues.
How To Use
- Set the Cron Trigger: Configure the 'Cron' node to define how often you want to check Hacker News (e.g., every 5 minutes).
- Initial HTTP Request: Set up the first 'HTTP Request' node to fetch the Hacker News URL ('https://news.ycombinator.com/') with 'string' response format.
- Introduce a Wait: Configure the 'Wait' node to pause for a short duration (e.g., 5 minutes) between content fetches.
- Second HTTP Request: Add another 'HTTP Request' node, identical to the first, to fetch the Hacker News content again.
- Configure the IF Node: In the 'IF' node, set the condition to compare the data from the first and second 'HTTP Request' nodes. Use an expression like
={{$node["HTTP Request"].json["data"]}} != {{$node["HTTP Request1"].json["data"]}}to check for differences. - Set up Telegram Alert: Configure the 'Telegram1' node with your chat ID and a relevant message to receive notifications when the IF condition is met (changes are detected).
