node-ansiparser

A parser for ANSI escape code sequences implementing the state machine described at vt100.net/emu/dec_ansi_parser. Version 2.2.1 is the latest stable release, with no further updates expected. It provides callbacks for printable characters, OSC, execute, CSI, ESC, and DCS sequences. Unlike alternatives (e.g., ansi-parser), this library follows the DEC ANSI parser specification closely, supports unicode, and allows injection of error handling. It is designed for Node.js and requires only a terminal object with specific callback methods.
