# Add hillshading
This example adds raster hillshading to a map by adding the [Mapbox Terrain-DEM](https://docs.mapbox.com/help/getting-started/mapbox-data/#mapbox-terrain-dem) raster tileset as a [`raster-dem` source](https://docs.mapbox.com/style-spec/reference/sources/#raster-dem) with a [`hillshade` layer](https://docs.mapbox.com/style-spec/reference/layers/#hillshade).
> Example code:
**JavaScript**
```html
Add hillshading
```
**React**
```jsx
import React, { useEffect, useRef } from 'react';
import * as mapboxgl from 'mapbox-gl/esm';
import 'mapbox-gl/dist/mapbox-gl.css';
const MapboxExample = () => {
const mapContainerRef = useRef();
const mapRef = useRef();
useEffect(() => {
mapRef.current = new mapboxgl.Map({
// TO MAKE THE MAP APPEAR YOU MUST
// ADD YOUR ACCESS TOKEN FROM
// https://account.mapbox.com
accessToken: 'YOUR_MAPBOX_ACCESS_TOKEN',
container: mapContainerRef.current,
style: 'mapbox://styles/mapbox/standard',
config: {
basemap: {
theme: 'monochrome'
}
},
center: [-119.55, 37.71],
zoom: 9
});
mapRef.current.on('load', () => {
mapRef.current.addSource('dem', {
type: 'raster-dem',
url: 'mapbox://mapbox.mapbox-terrain-dem-v1'
});
mapRef.current.addLayer({
id: 'hillshading',
source: 'dem',
type: 'hillshade',
slot: 'bottom'
});
});
return () => {
mapRef.current.remove();
};
}, []);
return ;
};
export default MapboxExample;
```
