Some actions will affect the entire kepler.lg instance state. The updaters for these actions is exported as combinedUpdaters. These updater take the entire instance state as the first argument. Read more about Using updaters​
Examples
import keplerGlReducer, {combinedUpdaters} from 'kepler.gl/reducers';
// Root Reducer
const reducers = combineReducers({
 keplerGl: keplerGlReducer,
 app: appReducer
});
​
const composedReducer = (state, action) => {
 switch (action.type) {
   // add data to map after receiving data from remote sources
   case 'LOAD_REMOTE_RESOURCE_SUCCESS':
     return {
       ...state,
       keplerGl: {
         ...state.keplerGl,
         // pass in kepler.gl instance state to combinedUpdaters
         map:  combinedUpdaters.addDataToMapUpdater(
          state.keplerGl.map,
          {
            payload: {
              datasets: action.datasets,
              options: {readOnly: true},
              config: action.config
