node-inspect-debugger

Yes, you can attach a CDP client to running Node.js processes inside containers to inspect locals, closures, and runtime state. This remote debugging capability allows you to query and control execution without modifying the deployed application code.

The primary prerequisites for Node.js CDP debugging are a running Node.js process launched with --inspect or --inspect-brk, and a CDP client like chrome-remote-interface to establish the connection for querying and controlling execution.

The built-in node inspect client provides interactive terminal debugging with breakpoints and call-stack inspection, while a programmatic CDP client enables scripted, automated flows for reproducible sessions and deeper runtime state querying in CI pipelines.

When attaching via the Chrome DevTools Protocol, you can inspect Node.js runtime states including locals, closures, and the call stack. CDP allows you to evaluate expressions and query execution state programmatically during local or remote debugging.
