Does it support TypeScript or bundled code?

Yes, the skill includes source map resolution to accurately map bundled or transpiled code back to its original source locations.

Do I need to modify my application code to use this?

No, it connects to running processes via the Node.js inspector protocol and injects probes dynamically without requiring any manual code changes.

Can I use this with Docker containers?

Yes, it supports connecting via container names or IDs, provided the Docker socket is accessible to the MCP container.

What are exceptionpoints?

Exceptionpoints automatically capture the state and stack trace whenever an error is thrown, helping you find the root cause of crashes without manual log insertion.

Is this debugging blocking or non-blocking?

It uses non-blocking probes, meaning the Node.js process continues to run while data is captured, making it safe for live environments compared to traditional breakpoints.

Debugs live Node.js backend processes using non-blocking tracepoints and real-time state inspection.

The Node.js Backend Debugging skill empowers Claude to troubleshoot API servers, worker processes, and backend scripts without stopping execution. By leveraging non-blocking tracepoints, logpoints, and exceptionpoints, it allows for deep inspection of call stacks and variables in production-like environments or Docker containers. This is essential for diagnosing intermittent bugs, performance bottlenecks, and server-side errors where traditional step-through debugging is impractical or disruptive, providing a seamless bridge between AI assistance and live process observability.
