SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires chrome-remote-interface.

What problem does it solve?

This skill resolves complex runtime issues in Node.js applications by providing deep visibility into execution state, call stacks, and variable scopes that standard logging cannot reach.

Core Features & Use Cases

  • Interactive Debugging: Utilize the built-in V8 inspector to set breakpoints, step through code, and inspect local or closure variables in real-time.
  • Automated Analysis: Leverage the Chrome DevTools Protocol (CDP) to script non-interactive debugging sessions, capture heap snapshots, or generate CPU profiles for performance tuning.
  • Use Case: When a TUI component or background worker behaves unexpectedly, use this skill to attach to the process, pause execution at a specific line, and evaluate the internal state of the application.

Quick Start

Use the node-inspect-debugger skill to attach to a running Node.js process by sending a SIGUSR1 signal and connecting the inspector to the target PID.

Frequently Asked Questions about node-inspect-debugger

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug a Node.js process using the Chrome DevTools Protocol?▼

You can attach to a running Node.js process by sending a SIGUSR1 signal and connecting the V8 inspector to the target PID, enabling real-time breakpoint management and call stack inspection.

How do I capture heap snapshots and CPU profiles for Node.js performance tuning?▼

Leverage the Chrome DevTools Protocol to script non-interactive debugging sessions, capturing heap snapshots and generating CPU profiles to perform deep Node.js performance tuning.

Can I set breakpoints and inspect closure variables in a Node.js background worker?▼

Yes, utilize the built-in V8 inspector to attach to the background worker process, pause execution at a specific line, and evaluate internal application state including local and closure variables.

Does Node.js debugging via CDP require the chrome-remote-interface package?▼

Yes, programmatic control over the Node.js V8 inspector requires the chrome-remote-interface dependency to interface with the Chrome DevTools Protocol for deep runtime debugging and state analysis.

What is the best way to analyze complex runtime issues that standard logging cannot reach in Node.js?▼

The best way is using the V8 inspector to gain deep visibility into execution state, call stacks, and variable scopes that standard logging cannot reach, resolving complex Node.js runtime issues.
