@sqlrooms/kepler ​

Kepler.gl integration for SQLRooms.

Use this package when you want a map-first analytics experience in a SQLRooms app, backed by DuckDB tables and SQL.

What this package provides ​

  • createKeplerSlice() to add Kepler state/actions to your Room store
  • KeplerMapContainer and KeplerPlotContainer for rendering maps/overlays
  • KeplerSidePanels for layer/filter/interaction UI
  • utilities for map config persistence and dataset synchronization

Installation ​

bash
npm install @sqlrooms/kepler @sqlrooms/room-shell @sqlrooms/duckdb @sqlrooms/ui

Quick start ​

tsx
import {useEffect} from 'react';
import {
  createKeplerSlice,
  KeplerMapContainer,
  KeplerSliceState,
} from '@sqlrooms/kepler';
import {
  createRoomShellSlice,
  createRoomStore,
  RoomShell,
  RoomShellSliceState,
} from '@sqlrooms/room-shell';

type RoomState = RoomShellSliceState & KeplerSliceState;

export const {roomStore, useRoomStore} = createRoomStore<RoomState>(
  (set, get, store) => ({
    ...createRoomShellSlice({
      config: {
        dataSources: [
          {
            type: 'url',
            tableName: 'earthquakes',
            url: 'https://huggingface.co/datasets/sqlrooms/earthquakes/resolve/main/earthquakes.parquet',
          },
        ],
      },
    })(set, get, store),
    ...createKeplerSlice()(set, get, store),
  }),
);

function MapPanel() {
  const mapId = useRoomStore((state) => state.kepler.config.currentMapId);
  const addTableToMap = useRoomStore((state) => state.kepler.addTableToMap);
  const isTableReady = useRoomStore((state) =>
    Boolean(state.db.findTableByName('earthquakes')),
  );

  useEffect(() => {
    if (!isTableReady || !mapId) return;
    void addTableToMap(mapId, 'earthquakes', {
      autoCreateLayers: true,
      centerMap: true,
    });
  }, [isTableReady, mapId, addTableToMap]);

  if (!mapId) return null;

  return <KeplerMapContainer mapId={mapId} />;
}

export function App() {
  return (
    <RoomShell roomStore={roomStore} className="h-screen">
      <MapPanel />
    </RoomShell>
  );
}

Common customization ​

Pass options to createKeplerSlice():

ts
createKeplerSlice({
  basicKeplerProps: {
    mapboxApiAccessToken: import.meta.env.VITE_MAPBOX_TOKEN,
  },
  actionLogging: false,
});
  • @sqlrooms/kepler-config for Zod schemas used by persisted Kepler config
  • @sqlrooms/room-shell for Room store composition and UI shell
  • @sqlrooms/duckdb for DuckDB-backed table loading/querying
