@signalk/nmea0183-signalk/dist/bin/nmea0183-signalk.js

A node.js/javascript parser for NMEA0183 sentences. Sentences are parsed to Signal K format.

#!/usr/bin/env node
"use strict";
// Stream NMEA 0183 sentences from stdin, emit Signal K deltas as JSON lines.
// Checksum validation is off because real-world NMEA streams often carry
// mid-stream corruption; callers can re-enable with a small wrapper if they
// need strict parsing.
