Instrumenting Node.js Internals
summary
A small Open Source tool called instrument attaches to Node processes and logs real runtime facts: which native modules are touched (example http and https), exact network calls shown to registry endpoints like registry.npmjs.org, and module loads recorded via an instrument.config.js that lists probes. Demo shows npm resolving mocha to 8.2.1 and prints headers and methods. It works locally but carries measurable overhead so it is not recommended for production.
