OptionalclusterMapLibre cluster options, forwarded verbatim to the underlying GeoJSON source.
Cluster options are applied at source creation time and cannot be changed via CustomGeoJSONModule.applyConfig. To change clustering, recreate the module.
A cluster is not among the shown features, so an event handler receives the rendered MapLibre
feature for it, with cluster, cluster_id and point_count in its properties.
The layers that render this source. CustomGeoJSONModule.create rejects a source without layers.
OptionalsourceThe MapLibre source ID. If absent, it is auto-generated as
custom-geojson-${instanceIndex}-${sourceName}. It is fixed at creation, like the source names.
The configuration of one logical source that a CustomGeoJSONModule manages.
Each entry is a single MapLibre GeoJSON source and its layers.
