Command-line interface for non-blocking debugging of Node.js backend processes. Connects via the Inspector Protocol (Chrome DevTools Protocol) and provides tracepoints, logpoints, exceptionpoints, and watch expressions without pausing execution.
| --port | Daemon server port | 2020 | | --session-id | Session for Node connection persistence | auto | | --json | Output as JSON (recommended for AI) | false | | --quiet | Suppress log messages | false | | --verbose | Enable debug output | false | | --timeout | Operation timeout | 30000 |
| debug | Connection, tracepoints, logpoints, exceptionpoints, watch, snapshots | | run | JavaScript execution in connected Node process |
CLI for debugging Node.js backend processes with non-blocking inspection. Use when the user needs to connect to Node.js processes (by PID, name, Docker, or port), set tracepoints/logpoints/exceptionpoints, capture call stacks and local variables, run JavaScript in the process context, or inspect console logs. Requires daemon; connect before other debug commands. Source: serkan-ozal/browser-devtools-skills.
