First of all, thank you for your library and for sharing the code. I am trying to export a given geojson coming from Turf JS in to a Shapefile project as a zip.
I am facing a problem when comparing results in QGis. The thing is that, as far as I can see in the code, POLYGON and MULTIPOLYGON collapse to the same Type, so the final file per type written into the temporary zip object shares its name (path), overwriting its content if some other file would have been generated previously with the same type (i. e.: Polygon and MultiPolygon).
An example of a geojson I am plugging in to the zip() method:
Is this a bug or is it the way the library is supposed to work?
I would expect as a result of executing zip() just one set of files (.dbf, .prj, .shp, .shx) inside a .zip.
Checking the library code, multiple sets of files (.dbf, .prj, .shp, .shx) would be generated depending on the geojson feature types, effectively dividing its content. I think that this behavior is a bit weird.
Could you please confirm or assist on how I can get just one set of files (.dbf, .prj, .shp, .shx) in a .zip representing the entire geojson original content?
In a GeoServer instance using WFS\GetFeature, that is what is returned (.dbf contains all features properties).
