### visStateUpdaters

Updaters for `visState` reducer. Can be used in your root reducer to directly modify kepler.gl's state. Read more about [Using updaters](/docs/api-reference/advanced-usages/using-updaters.md)

**Examples**

```javascript
import keplerGlReducer, {visStateUpdaters} from '@kepler.gl/reducers';
// Root Reducer
const reducers = combineReducers({
 keplerGl: keplerGlReducer,
 app: appReducer
});

const composedReducer = (state, action) => {
 switch (action.type) {
   case 'CLICK_BUTTON':
     return {
       ...state,
       keplerGl: {
         ...state.keplerGl,
         foo: {
            ...state.keplerGl.foo,
            visState: visStateUpdaters.enlargeFilterUpdater(
              state.keplerGl.foo.visState,
              {idx: 0}
            )
