## What it is
A tiny, dependency-free JavaScript library that converts KML and GPX documents into GeoJSON, usable in both browsers and Node.js. It also ships a CLI for quick file conversion.

## Use cases
- convert kml files to geo
- convert gpx tracks to geo for leaflet maps
- parse gpx waypoints in node.js
- turn google earth kml placemarks into geo features
- batch convert gps exchange files from the command line
- load kml data into mapbox or leaflet

## When to choose
- you need KML or GPX data as GeoJSON in a browser or Node.js app
- you want a tiny, dependency-free converter
- you use Leaflet or Mapbox and need to ingest KML/GPX layers

## When to avoid
- you need to convert GeoJSON back to KML or GPX
- you need full fidelity for all KML features like NetworkLinks or tours
- you work outside the JavaScript ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: parser, serialization, cli
- domain: web-development, developer-tools
- platform: browser, cli, cross-platform
- tags: geo, kml, gpx, gis, leaflet, format-conversion, maps, geospatial, nodejs
