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: Set breakpoints, step through code, and inspect local or closure variables using the built-in V8 inspector.
  • Process Attachment: Attach to long-running processes like TUI gateways or dev servers to diagnose crashes or performance bottlenecks.
  • Use Case: When a specific UI component in the Hermes TUI behaves unexpectedly, use this skill to pause execution at the render line and inspect the component state and props directly.

Quick Start

Use the node-inspect-debugger skill to attach to the running process with the specified process ID and set a breakpoint at the target file and line number.

Frequently Asked Questions about node-inspect-debugger

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

FAQPage Schema
How do I set breakpoints and inspect variables in a Node.js application?▼

You can debug Node.js applications by using the V8 inspector and Chrome DevTools Protocol to interactively set breakpoints, step through code, and inspect local or closure variables.

Can I attach a debugger to a long-running Node.js process to diagnose crashes?▼

Yes, you can attach to long-running Node.js processes like TUI gateways or dev servers to diagnose crashes and performance bottlenecks using process attachment via the V8 inspector.

Does Node.js debugging with this method require the --inspect flag?▼

Yes, Node.js debugging requires a runtime environment supporting the --inspect flags to expose the V8 inspector endpoint for Chrome DevTools Protocol communication.

What is the best way to capture a heap snapshot for local development troubleshooting?▼

The best way to capture heap snapshots for local development troubleshooting is using the V8 inspector via Chrome DevTools Protocol to gain deep visibility into application memory and execution state.

How does the Chrome DevTools Protocol facilitate interactive debugging in Node.js?▼

The Chrome DevTools Protocol facilitates interactive debugging in Node.js by enabling programmatic breakpoint management, call stack analysis, and heap snapshot capture for local development and production troubleshooting.

Do I need a CDP client library for Node.js debugging automation?▼

Yes, you need an optional CDP client library like chrome-remote-interface to automate Node.js debugging tasks programmatically rather than relying solely on interactive breakpoint sessions.
