The **node‑verror** library provides drop‑in replacements for JavaScript’s built‑in `Error` that let developers create richer, more informative errors. It adds printf‑style messages, error‑cause chaining, and first‑class metadata (info properties), and includes helpers such as `VError`, `WError`, `SError`, and `MultiError` for wrapping, hiding, or aggregating errors—making it useful for Node.js developers who need clear, debuggable error handling in servers, CLI tools, and libraries.
