Redact‑pii is a Node‑compatible TypeScript library that scans arbitrary text and replaces personal data (names, emails, phone numbers, credit‑card numbers, SSNs, addresses, URLs, etc.) with configurable placeholders. It offers both synchronous and promise‑based APIs, lets developers add or disable built‑in regex rules, plug in custom redaction functions, and optionally combine the built‑in patterns with Google Cloud DLP for more comprehensive, multilingual PII detection. Ideal for developers who need to scrub sensitive information from logs, messages, or documents before storage or sharing.
