useMapDataset

Store for datasets on one map. Call it with the map id from @map-loaded.

Vue

const {
  addDataset,
  removeDataset,
  removeComponent,
  getDatasets,
  getDatasetIds,
  getAllComponentsByType,
  setMapId,
} = useMapDataset(mapId);

Method	Role
addDataset(dataset)	Add tree to the map (respects dependsOn)
removeDataset(dataset)	Remove tree from the map
removeComponent(node)	Remove one node (e.g. a list row)
getDatasets()	Root datasets
getDatasetIds()	Ref<string[]> of root ids
getAllComponentsByType<T>(type)	e.g. 'list', 'identify'
setMapId(id)	Bind after mount

function onMapLoaded(map: MapSimple) {
  const { addDataset } = useMapDataset(map.id);
  addDataset(createRootDataset('Sample'));
}

React

Same methods. The hook also returns datasetVersion (number) so list UIs re-render after add/remove.

const { addDataset, datasetVersion } = useMapDataset(map.id);
