Get Mapbox Token
Kepler.gl is built on top of Mapbox GL. A mapbox account and an access token are needed to use kepler.gl in your app. Get a Mapbox Access Token at mapbox.com.
Basic Usage
1. Mount reducer
Kepler.gl uses Redux to manage its internal state, along with react-palm middleware to handle side effects. Mount kepler.gl reducer in your store, apply taskMiddleware.
import keplerGlReducer from 'kepler.gl/reducers';
import {createStore, combineReducers, applyMiddleware} from 'redux';
import {taskMiddleware} from 'react-palm/tasks';
​
const reducer = combineReducers({
  // <-- mount kepler.gl reducer in your app
  keplerGl: keplerGlReducer,
​
  // Your other reducers here
  app: appReducer
});
​
// create store
const store = createStore(reducer, {}, applyMiddleware(taskMiddleware));
If you mount keplerGlReducer in another address instead of keplerGl, or it is not mounted at root of your reducer, you will need to specify the path to it when you mount the component with the getState prop.
2. Mount component
import KeplerGl from 'kepler.gl';
​
const Map = props => (
  <KeplerGl
      id="foo"
      mapboxApiAccessToken={token}
      width={width}
      height={height}/>
);
3. Add data to map
In order to interact with a kepler.gl instance and add new data to it, you can dispatch the addDataToMap action from anywhere inside your app. It adds dataset(s) to a kepler.gl instance and updates the full configuration (mapState, mapStyle, visState).

import {addDataToMap} from 'kepler.gl/actions';
​
this.props.dispatch(
  addDataToMap({
    // datasets
    datasets: {
      info: {
        label: 'Sample Taxi Trips in New York City',
        id: 'test_trip_data'
      },
      data: sampleTripData
    },
    // option
    option: {
      centerMap: true,
      readOnly: false
    },
    // config
    config: {
      mapStyle: {styleType: 'light'}
    }
  })
);
