Since v5.1

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

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

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}>
        <Source id="my-data" type="geojson" data={geojson}>
              'circle-radius': 10,
              'circle-color': '#007cbf'
            }} />


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

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.
