- install
leaflet.heat
via npm :npm i leaflet.heat
- import the library:
import "leaflet.heat";
- Create a map component and use an effect to load the map and instantiate
L.heatLayer
Here is an example from the library’s github page written in React without react-leaflet components:
function Map() {
useEffect(() => {
var map = L.map("map").setView([-37.87, 175.475], 12);
L.tileLayer("https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png", {
attribution:
'© <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);
const points = addressPoints
? addressPoints.map((p) => {
return [p[0], p[1]];
})
: [];
L.heatLayer(points).addTo(map);
}, []);
return <div id="map" style={{ height: "100vh" }}></div>;
}
