React-Leaflet marker files not found

Question

I've got very simple code to display a map using react-leaflet and place a marker on it. However, i get the following two errors in my browser console

GET http://localhost:8080/marker-icon-2x.png 404 (Not Found)

GET http://localhost:8080/marker-shadow.png 404 (Not Found)

I tried to fix this issue by downloading those two images and placing them at the root. It works. However, how can i change the URL the react-leaflet marker element looks for the marker images? I'd like to store them in "./images" rather than at the root.

Answer 1

Try to do this :)

React leaflet for some reason do not include images and you will need to reset default icons image.

Below is some working example, I hope it will solve your issue.

You also can add icons from one of public link

https://cdnjs.com/libraries/Leaflet.awesome-markers

import React, { Component } from 'react';
import L from 'leaflet';
import {
    Map, TileLayer, Marker, Popup
} from 'react-leaflet'
import 'leaflet/dist/leaflet.css';
import './style.css';


import icon from 'leaflet/dist/images/marker-icon.png';
import iconShadow from 'leaflet/dist/images/marker-shadow.png';

let DefaultIcon = L.icon({
    iconUrl: icon,
    shadowUrl: iconShadow
});

L.Marker.prototype.options.icon = DefaultIcon;

It seems not all stuff is properly integrated together when using react, leaflet and react-leaflet. I had the same problem and found this

You need to setup leafelet itself again, as something brokes after importing leaflet.css.

Hope it helps

Answer 3

Copy all images from leaflet package to the public directory:

cp node_modules/leaflet/dist/images/* {PUBLIC_WEB_DIRECTORY}/leaflet_images/

Fix the path in Leaflet

import L from 'leaflet';
L.Icon.Default.imagePath='leaflet_images/';

Answer 4

Adding answer for Next.js

1. Copy over marker icon from node_modules/leaflet/dist/images to public/images something like /images/marker-icon.png

2. Create Leaflet icon reference and use the reference in Marker

const icon = L.icon({ iconUrl: "/images/marker-icon.png" });

// some other code

<Marker key={obj.id} position={position} icon={icon}>

// rest of the code

Here is the solution that worked for me:

I added the following lines in the top of the file:

import { MapContainer, TileLayer, Marker, Popup } from 'react-leaflet';
import 'leaflet/dist/leaflet.css';
import L from 'leaflet';

delete L.Icon.Default.prototype._getIconUrl;

L.Icon.Default.mergeOptions({
    iconRetinaUrl: require('leaflet/dist/images/marker-icon-2x.png').default,
    iconUrl: require('leaflet/dist/images/marker-icon.png').default,
    shadowUrl: require('leaflet/dist/images/marker-shadow.png').default
});
