keplerGlReducer

Kepler.gl reducer to be mounted to your store. You can mount keplerGlReducer at property keplerGl, if you choose to mount it at another address e.g. foo you will need to specify it when you mount KeplerGl component in your app with getState: state => state.foo

Examples

import keplerGlReducer from 'kepler.gl/reducers';
import {createStore, combineReducers, applyMiddleware, compose} from 'redux';
import {taskMiddleware} from 'react-palm/tasks';
const initialState = {};
const reducers = combineReducers({
// <-- mount kepler.gl reducer in your app
keplerGl: keplerGlReducer,
// Your other reducers here
app: appReducer
});
// using createStore
export default createStore(reducer, initialState, applyMiddleware(taskMiddleware));

keplerGlReducer.initialState

Return a reducer that initiated with custom initial state. The parameter should be an object mapping from subreducer name to custom subreducer state, which will be shallow merged with default initial state.

Default subreducer state:

Parameters

  • iniSt Object custom state to be merged with default initial state

Examples

const myKeplerGlReducer = keplerGlReducer
.initialState({
uiState: {readOnly: true}
});

keplerGlReducer.plugin

Returns a kepler.gl reducer that will also pass each action through additional reducers spiecified. The parameter should be either a reducer map or a reducer function. The state passed into the additional action handler is the instance state. It will include all the subreducers visState, uiState, mapState and mapStyle. .plugin is only meant to be called once when mounting the keplerGlReducer to the store. Note This is an advanced option to give you more freedom to modify the internal state of the kepler.gl instance. You should only use this to adding additional actions instead of replacing default actions.

Parameters

Examples

const myKeplerGlReducer = keplerGlReducer
.plugin({
// 1. as reducer map
HIDE_AND_SHOW_SIDE_PANEL: (state, action) => ({
...state,
uiState: {
...state.uiState,
readOnly: !state.uiState.readOnly
}
})
})
.plugin(handleActions({
// 2. as reducer
'HIDE_MAP_CONTROLS': (state, action) => ({
...state,
uiState: {
...state.uiState,
mapControls: hiddenMapControl
}
})
}, {}));
