This component allows apps to create a map source using React. It may contain Layer components as children.

import * as React from 'react';
import ReactMapGL, {Source, Layer} from 'react-map-gl';

const EMPTY_STYLE = {
  version: 8,
  sources: {},
  layers: []
};

const geojson = {
  type: 'FeatureCollection',
  features: [
    {type: 'Feature', geometry: {type: 'Point', coordinates: [-122.4, 37.8]}}
  ]
};

class Map extends React.Component {
  render() {
    return (
      <ReactMapGL latitude={37.78} longitude={-122.41} zoom={8} mapStyle={EMPTY_STYLE}>
        <Source id="my-data" type="geojson" data={geojson}>
          <Layer
            id="point"
            type="circle"
            paint={{
              'circle-radius': 10,
              'circle-color': '#007cbf'
            }} />
        </Source>
      </ReactMapGL>
    );
  }
}

Properties

The props provided to this component should be conforming to the Mapbox source specificationor CanvasSourceOptions.

mapStyle defaults to mapbox://styles/mapbox/light-v8 which requires a token, to use an empty base map, you need to override the prop. See the EMPTY_STYLE object in the example.

When props change shallowly, the component will attempt to update the source. Do not define objects/arrays inline to avoid perf hit.

Once a <Source> is mounted, the following props should not change. If add/remove multiple JSX sources dynamically, make sure you use React's key prop to give each element a stable identity.

id (String)

Unique identifier of the source. If not provided, a default id will be assigned.

type (String, required)

Type of the source.
