marker icon isn't showing in Leaflet

Question

I \'ve put together a very simple React / Leaflet demo but the marker icon is not showing at all. Full running code is here.

Here\'s what I have in my componentDid

Answer 1

Try to add an icon:

const myIcon = L.icon({
   iconUrl: 'myIcon.png',
   // ...
});

L.marker([37.98, 23.72], {icon: myIcon})
  .addTo(this.map)

Perhaps you have some problems with the default one: https://leafletjs.com/reference-1.6.0.html#icon-default
