Actualmente estoy usando esta biblioteca para mi proyecto.

Quiero agregar diferentes íconos para categorías, como aquí 
Lo agregué a JSON, pero no puedo mostrar el ícono
{ "type": "Feature", "geometry": { "type": "Point", "coordinates": [ xxxxx, xxxxxx] }, "properties": { "name": "xxx", "city": "xxx", "address": "xxx", "icon": { "iconUrl": "https icon url", "iconSize": [55, 55], "iconAnchor": [50, 50], "popupAnchor": [-15, -50], "className": "dot" } } },Hay un lugar en este código que debe cambiarse: prospecto-tienda-ubicador
var myIcon = L.icon({ iconUrl: 'marker.png', iconSize: [30, 40] }); const shopsLayer = L.geoJSON(storeList, { onEachFeature: onEachFeature, pointToLayer: function(feature, latlng) { return L.marker(latlng, { icon: myIcon }); } });En lugar de un marcador establecido globalmente, debe agregarlo a la función pointToLayer.
const shopsLayer = L.geoJSON(storeList, { onEachFeature: onEachFeature, pointToLayer: function(feature, latlng) { // check what you have exactly in the 'feature' // console.log(feature); var myIcon = L.icon({ // I'm not sure of the path, that's why it's above console.log(feature); iconUrl: feature.properties.icon.iconUrl, iconSize: feature.properties.icon.iconSize, // and here is the rest of the icon configuration }); return L.marker(latlng, { icon: myIcon }); } });
