Add custom marker to a Leaflet map

Leaflet map library allows creating markers of different types and forms.

In this code sample, we would like to show how you can use icons generated by Geoapify Marker Icon API as Leaflet markers. The full version of the code sample you can find on JSFiddle.

1. Generate an icon and get the icon URL

Design a map marker icon with the Marker Icon API playground. You will require an API key to use the icon in your project. Register for Free, no credit card required.

2. Create a marker with the icon

const markerIcon = L.icon({
  iconUrl: `${myAPIKey}`,
  iconSize: [31, 46], // size of the icon
  iconAnchor: [15.5, 42], // point of the icon which will correspond to marker's location
  popupAnchor: [0, -45] // point from which the popup should open relative to the iconAnchor
const zooMarker = L.marker([48.096980, 11.555466], {
  icon: markerIcon

3. Add a popup to the marker

Here is an example of a simple text popup:

const zooMarkerPopup = L.popup().setContent("This is Munich Zoo");
const zooMarker = L.marker([48.096980, 11.555466], {
  icon: markerIcon

The Leaflet library lets you to generate more complicated popups based on an HTML element provided to the setContent() function.
