**match‑url‑wildcard** is a tiny JavaScript utility that checks whether a given URL (with optional scheme, port, path, or IP address) conforms to a flexible pattern that can include wildcards (`*`), leading dots, and trailing dots. It’s intended for developers who need simple, rule‑based URL filtering or routing in Node.js or browser environments—e.g., testing URLs, whitelisting domains, or validating request targets.
