`npm-module-wrapper` (published as **object‑wrapper**) is a tiny utility that takes any JavaScript object or constructor and returns a version whose every method is intercepted by a user‑supplied wrapper function. The wrapper receives detailed metadata (original function, namespace, call arguments, constructor flag, etc.), letting developers inject custom behavior such as logging, error handling, or test‑framework integration. It’s aimed at library authors and tool developers who need to transparently augment existing modules without modifying their source.
