rtf‑stream‑parser is a Node.js library that parses RTF byte streams, tokenizes them, and extracts the encapsulated HTML or plain‑text payloads used by Outlook/Exchange email formats. It provides high‑level synchronous and asynchronous functions as well as low‑level Transform streams, targeting developers (e.g., e‑discovery, email‑processing tools) who need to de‑encapsulate and correctly decode RTF‑wrapped content.
