Log Streaming
Stream real-time logs from your deployed worker for debugging and monitoring using npm run tail.
Starting the Log Stream
npm run tail
This requires CLOUDFLARE_API_TOKEN to be set in your .env file. The stream outputs color-formatted log entries to the terminal and writes raw JSON lines to tail-logs.jsonl for later analysis.
Session Management
Log streaming sessions have a limited lifespan set by Cloudflare. The script handles this automatically:
- Fetches the actual session expiry time from the Cloudflare API.
- Restarts the session with a 5-minute buffer before expiry.
- Cleans up stale sessions on startup.
- Shuts down gracefully on Ctrl+C.
Output Format
Log entries are color-coded by event type and status:
- HTTP events — Method, status code, URL, user agent, geolocation (country, ASN, IP), and per-server delivery results.
- Email events — From/to/subject and interpreter results.
Config Resolution
The script discovers config.json from the current directory, project root, or XDG config directory. It uses the worker_name from your config to identify the correct Worker on Cloudflare.
