tootallnate/pcre-to-regexp

pcre‑to‑regexp is a tiny Node.js library that parses PCRE‑style regular‑expression strings (including delimiters, flags and named capture groups) and returns an equivalent JavaScript `RegExp` object, optionally filling an array with the capture names. It’s aimed at developers who need to reuse existing PCRE patterns—e.g., from server‑side code or third‑party libraries—in client‑side or Node.js JavaScript environments.
