LeafletJS GeoMan into JSON data

Question

I've added GeoMan to my leaflet map and just wondering if there is a way I can export all the drawn features into JSON. I'm using it for development only so the JSON can go into console.log

I'm just struggling to work it out. This is the only code I have so far

map.pm.toggleGlobalDragMode();
map.pm.addControls({
  position: 'topright',
  editMode: true,



});

layer.pm.enable({ pinning: true, snappable: true })

You can use this code:

function generateGeoJson(){
    var fg = L.featureGroup();    
    var layers = findLayers(map);
        layers.forEach(function(layer){
        fg.addLayer(layer);
         });
    console.log(fg.toGeoJSON());
}

function findLayers(map) {
    var layers = [];
    map.eachLayer(layer => {
      if (
        layer instanceof L.Polyline || //Don't worry about Polygon and Rectangle they are included in Polyline
        layer instanceof L.Marker ||
        layer instanceof L.Circle ||
        layer instanceof L.CircleMarker
      ) {
        layers.push(layer);
      }
    });

    // filter out layers that don't have the leaflet-geoman instance
    layers = layers.filter(layer => !!layer.pm);

    // filter out everything that's leaflet-geoman specific temporary stuff
    layers = layers.filter(layer => !layer._pmTempLayer);

    return layers;
  }

Additional Information:

• In the next Realease there will be a function to get all layers.
• pinning is only working with the pro version
