In the spirit of, "it should just work," 

    this package lets you convert raw expo-location returns
    to the most popular geospatial formats: geojson, gpx, and kml

        in a very opinionated manner.

v2.0.0

• Rewritten in Typescript.
• Broke out each format into separate modules.
  • Decoupled GPX and KML from GEOJSON.
• Removed a bunch of unnecessary formats (Polygon, Route, etc).
• Switched XML rendering to fast-xml-parser.
• Links don't provide or validate mime types for the sake of sanity.
• Format Specific Details:
  • GEOJSON
    • Output geometries: Point, MultiPoint, or LineString.
    • Wrappers: GeometryCollection, FeatureCollection, Feature, or none.
  • GPX
    • Output types: WayPoint or Track.
    • Metadata is stored in the "global" property.
  • KML
