preact-leaflet

🚧 This library is current under construction. 🚧

Currently Supporting the following Leaflet components:

• MapContainer
• Marker
• TileLayer

Example

import { h } from 'preact';
import { SvgIcon } from './SvgIcon';
import {
  MapContainer,
  TileLayer,
  Marker,
} from 'preact-leaflet';
import 'leaflet/dist/leaflet.css';
import './styles.css';
