forwardActions

A set of helpers to forward dispatch actions to a specific instance reducer

forwardTo

Returns an action dispatcher that wraps and forwards the actions to a specific instance
Parameters
Examples
// action and forward dispatcher
import {toggleSplitMap, forwardTo} from 'kepler.gl/actions';
import {connect} from 'react-redux';
​
const MapContainer = props => (
<div>
<button onClick={() => props.keplerGlDispatch(toggleSplitMap())}/>
</div>
)
​
const mapDispatchToProps = (dispatch, props) => ({
dispatch,
keplerGlDispatch: forwardTo(‘foo’, dispatch)
});
​
export default connect(
state => state,
mapDispatchToProps
)(MapContainer);

isForwardAction

Whether an action is a forward action
Parameters
  • action Object the action object
Returns boolean boolean - whether the action is a forward action

unwrap

Unwrap an action
Parameters
  • action Object the action object
Returns Object unwrapped action

wrapTo

Wrap an action into a forward action that only modify the state of a specific kepler.gl instance. kepler.gl reducer will look for signatures in the action to determine whether it needs to be forwarded to a specific instance reducer.
wrapTo can be curried. You can create a curried action wrapper by only supply the id argument
A forward action looks like this
{
type: "@@kepler.gl/LAYER_CONFIG_CHANGE",
payload: {
type: '@@kepler.gl/LAYER_CONFIG_CHANGE',
payload: {},
meta: {
// id of instance
_id_: id
// other meta
}
},
meta: {
_forward_: '@redux-forward/FORWARD',
_addr_: '@@KG_id'
}
};
Parameters
  • id string The id to forward to
  • action Object the action object {type: string, payload: *}
Examples
import {wrapTo, togglePerspective} from 'kepler.gl/actions';
​
// This action will only dispatch to the KeplerGl instance with `id: map_1`
this.props.dispatch(wrapTo('map_1', togglePerspective()));
​
// You can also create a curried action for each instance
const wrapToMap1 = wrapTo('map_1');
this.props.dispatch(wrapToMap1(togglePerspective()));

ActionTypes

Kepler.gl action types, can be listened by reducers to perform additional tasks whenever an action is called in kepler.gl
Type: Object​
Examples
// store.js
import {handleActions} from 'redux-actions';
import {createStore, combineReducers, applyMiddleware} from 'redux';
import {taskMiddleware} from 'react-palm/tasks';
​
import keplerGlReducer from 'kepler.gl/reducers';
import {ActionTypes} from 'kepler.gl/actions';
​
const appReducer = handleActions(
{
// listen on kepler.gl map update action to store a copy of viewport in app state
[ActionTypes.UPDATE_MAP]: (state, action) => ({
...state,
viewport: action.payload
})
},
{}
);
​
const reducers = combineReducers({
app: appReducer,
keplerGl: keplerGlReducer
});
​
export default createStore(reducers, {}, applyMiddleware(taskMiddleware));

mapStyleActions

Request map style style object based on style.url.
Parameters

set3dBuildingColor

Set 3d building layer group color
Parameters

main

Main kepler.gl actions, these actions handles loading data and config into kepler.gl reducer. These actions is listened by all subreducers,

addDataToMap

Add data to kepler.gl reducer, prepare map with preset configuration if config is passed. Kepler.gl provides a handy set of utils to parse data from different formats to the data object required in dataset. You rarely need to manually format the data obejct.
Use KeplerGlSchema.getConfigToSave to generate a json blob of the currents instance config. The config object value will always have higher precedence than the options properties.
Kepler.gl uses dataId in the config to match with loaded dataset. If you pass a config object, you need to match the info.id of your dataset to the dataId in each layer, filter and interactionConfig.tooltips.fieldsToShow
Parameters
  • data Object​
    • data.datasets (Array<Object> | Object) *required datasets can be a dataset or an array of datasets
      Each dataset object needs to have info and data property.
      • data.datasets.info Object -info of a dataset
        • data.datasets.info.id string id of this dataset. If config is defined, id should matches the dataId in config.
        • data.datasets.info.label string A display name of this dataset
      • data.datasets.data Object *required The data object, in a tabular format with 2 properties fields and rows
        • data.datasets.data.fields Array<Object> *required Array of fields,
          • data.datasets.data.fields.name string *required Name of the field,
        • data.datasets.data.rows Array<Array> *required Array of rows, in a tabular format with fields and rows
    • data.options Object​
      • data.options.centerMap boolean default: true if centerMap is set to true kepler.gl will
        place the map view within the data points boundaries. options.centerMap will override config.mapState if passed in.
      • data.options.readOnly boolean default: false if readOnly is set to true
        the left setting panel will be hidden
      • data.options.keepExistingConfig boolean whether to keep exiting map data and associated layer filter interaction config default: false.
    • data.config Object this object will contain the full kepler.gl instance configuration {mapState, mapStyle, visState}
Examples
// app.js
import {addDataToMap} from 'kepler.gl/actions';
​
const sampleTripData = {
fields: [
{name: 'tpep_pickup_datetime', format: 'YYYY-M-D H:m:s', type: 'timestamp'},
{name: 'pickup_longitude', format: '', type: 'real'},
{name: 'pickup_latitude', format: '', type: 'real'}
],
rows: [
['2015-01-15 19:05:39 +00:00', -73.99389648, 40.75011063],
['2015-01-15 19:05:39 +00:00', -73.97642517, 40.73981094],
['2015-01-15 19:05:40 +00:00', -73.96870422, 40.75424576]
]
};
​
const sampleConfig = {
visState: {
filters: [
{
id: 'me',
dataId: 'test_trip_data',
name: 'tpep_pickup_datetime',
type: 'timeRange',
enlarged: true
}
]
}
};
​
this.props.dispatch(
addDataToMap({
datasets: {
info: {
label: 'Sample Taxi Trips in New York City',
id: 'test_trip_data'
},
data: sampleTripData
},
options: {
centerMap: true,
readOnly: false,
keepExistingConfig: false

keplerGlInit

Initialize kepler.gl reducer. It is used to pass in mapboxApiAccessToken to mapStyle reducer.
Parameters
  • payload Object​
    • payload.mapboxApiAccessToken string mapboxApiAccessToken to be saved to mapStyle reducer
    • payload.mapboxApiUrl string mapboxApiUrl to be saved to mapStyle reducer.
    • payload.mapStylesReplaceDefault Boolean mapStylesReplaceDefault to be saved to mapStyle reducer

receiveMapConfig

Pass config to kepler.gl instance, prepare the state with preset configs. Calling KeplerGlSchema.parseSavedConfig to convert saved config before passing it in is required.
You can call receiveMapConfig before passing in any data. The reducer will store layer and filter config, waiting for data to come in. When data arrives, you can call addDataToMap without passing any config, and the reducer will try to match preloaded configs. This behavior is designed to allow asynchronous data loading.
It is also useful when you want to prepare the kepler.gl instance with some preset layer and filter settings. Note Sequence is important, receiveMapConfig needs to be called before data is loaded. Currently kepler.gl doesn't allow calling receiveMapConfig after data is loaded. It will reset current configuration first then apply config to it.
Parameters
  • config Object *required The Config Object
  • options Object *optional The Option object
    • options.centerMap boolean default: true if centerMap is set to true kepler.gl will
      place the map view within the data points boundaries
    • options.readOnly boolean default: false if readOnly is set to true
      the left setting panel will be hidden
    • options.keepExistingConfig boolean whether to keep exiting layer filter and interaction config default: false.
Examples
import {receiveMapConfig} from 'kepler.gl/actions';
import KeplerGlSchema from 'kepler.gl/schemas';
​
const parsedConfig = KeplerGlSchema.parseSavedConfig(config);
this.props.dispatch(receiveMapConfig(parsedConfig));
