How to add custom markers icons in Here Maps API 3.0

Question

I want to use custom markers using Here Maps with JavaScript, but I tried the documentation and unfortunately I don't understand how to set a custom marker with a custom icon.

In this sample bellow I set a position and marker, but I can't figure out how to set my custom marker with .png or .svg icons and set as the default marker.

Link to the docs of Here Maps

function addMarkersToMap(map) {
  var parisMarker = new H.map.Marker({
    lat: 48.8567,
    lng: 2.3508
  });
  map.addObject(parisMarker);

  var romeMarker = new H.map.Marker({
    lat: 41.9,
    lng: 12.5
  });
  map.addObject(romeMarker);

  var berlinMarker = new H.map.Marker({
    lat: 52.5166,
    lng: 13.3833
  });
  map.addObject(berlinMarker);

  var madridMarker = new H.map.Marker({
    lat: 40.4,
    lng: -3.6833
  });
  map.addObject(madridMarker);

  var londonMarker = new H.map.Marker({
    lat: 51.5008,
    lng: -0.1224
  });
  map.addObject(londonMarker);
}

// Initialize the platform object:
const platform = new H.service.Platform({
  app_id: 'XXXXXXXXXXXXXX',
  app_code: 'XXXXXXXXXXX',
  useCIT: true,
  useHTTPS: true,
});

const maptypes = platform.createDefaultLayers();

// Instantiate (and display) a map object:
this.map = new H.Map(
  this.$el.querySelector('#mapContainer'),
  maptypes.normal.map, {
    zoom: 4,
    center: {
      lat: 50,
      lng: 5
    },
  },
);

var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(this.map));

// Create the default UI components
var ui = H.ui.UI.createDefault(this.map, maptypes, 'pt-BR');

// Now use the map as required...
addMarkersToMap(this.map);

Thanks.

To specify a custom image as a marker icon, create an H.map.Icon instance with your image (and custom options, when needed):

// using a PNG icon with its natural size (which is 32x32 in this case)
var pngIcon = new H.map.Icon("https://cdn0.iconfinder.com/data/icons/daily-boxes/150/phone-box-32.png");      

// optionally - resize a larger PNG image to a specific size
var pngIcon = new H.map.Icon("https://cdn3.iconfinder.com/data/icons/tourism/eiffel200.png", {size: {w: 56, h: 56}});

// optionally - resize a larger SVG image to a specific size
var svgIcon = new H.map.Icon("https://image.flaticon.com/icons/svg/190/190488.svg", {size: {w: 32, h: 32}});

Then, when creating the specific marker (H.map.Marker), set the icon option to the custom icon:

var marker = new H.map.Marker({
    lat: 48.8567,
    lng: 2.3508
  }, {
    icon: customIcon
  }
);

Alternatively you can use an H.mapDomIcon, when you use markers (H.map.DomMarker) with HTML/SVG content.

Example with different PNG and SVG marker icons

#mapContainer {
  width: 100%;
  height: 400px;
  background: grey;
}

As far as I know, there is no such functionality to just set a default marker icon for the map (e.g. map.setDefaultMarkerIcon(...)). Either you just create a custom icon, which you can use, when instantiating a marker:

var icon = new H.map.Icon("...");
var marker = new H.map.Marker({lat: 48.8567, lng: 2.3508}, {icon: icon});

Or encapsulate the marker creation into a function and create the markers via:

var defaultIcon = new H.map.Icon("...");  

function createMarker(lat, lng) {
  return new H.map.Marker({lat: lat, lng: lng}, {icon: defaultIcon});
}

var marker = createMarker(48.8564, 2.3564);

More information about customizing markers and their icons

Also your sample code had some remainder code that can cause an error, when unnoticed:

this.$el.querySelector('#mapContainer')

so In order to provide a working example, I just used a simpler solution to select the <div> element, which will be used as the map container:

document.querySelector('#mapContainer')

In case you are getting coordinates from database.

<script>
var contractors = <?php echo json_encode($contractors); ?>;
var contractorIcon = new H.map.Icon("https://img.icons8.com/color/64/000000/worker-male.png", {size: {w: 36, h: 36}});
for (let con = 0; con < contractors.length; con++) { 
        var parisMarker = new H.map.Marker(
                 {lat:coordinates[i], lng: coordinates[i+1]}, 
                 {icon: contractorIcon}
);
</script>
