MapboxLayer
MapboxLayer
is an implementation of Mapbox GL JS's CustomLayerInterface API. By adding a MapboxLayer
instance to an mapbox map, one can render any deck.gl layer inside the mapbox canvas / WebGL2 context. This is in contrast to the traditional deck.gl/mapbox integration where the deck.gl layers are rendered into a separate canvas over the base map.
See the Mapbox map.addLayer(layer, before?)
API for how to add a layer to an existing layer stack.
Example
import {MapboxLayer} from '@deck.gl/mapbox';
import {ScatterplotLayer} from '@deck.gl/layers';
const map = new mapboxgl.Map({...});
const myScatterplotLayer = new MapboxLayer({
id: 'my-scatterplot',
type: ScatterplotLayer,
data: [
{position: [-74.5, 40], size: 100}
],
getPosition: d => d.position,
getRadius: d => d.size,
getColor: [255, 0, 0]
});
// wait for map to be ready
map.on('load', () => {
// insert before the mapbox layer "waterway_label"
map.addLayer(myScatterplotLayer, 'waterway_label');
// update the layer
myScatterplotLayer.setProps({
getColor: [0, 0, 255]
});
});
Constructor
import {MapboxLayer} from '@deck.gl/mapbox';
new MapboxLayer(props);
Parameters:
props
(object)props.id
(string) - an unique id is required for each layer.props.type
(Layer
, optional) - a class that extends deck.gl's baseLayer
class. Required ifdeck
is not provided.props.deck
(Deck
, optional) - aDeck
instance that controls the rendering of this layer. If provided, the layer will be looked up from its layer stack byid
at render time, and all other props are ignored. It's recommended that you use the MapboxOverlay class where aDeck
instance is automatically managed.- Optional: any other prop needed by this type of layer. See deck.gl's layer catalog for documentation and examples on how to create layers.
Methods
setProps(props)
const layer = new MapboxLayer({
id: 'my-scatterplot',
type: ScatterplotLayer,
...
});
map.addLayer(layer);
layer.setProps({
radiusScale: 2
});
Update a layer after it's added. Has no effect if props.deck
is provided.
