Function wfsSource

Adapter factory for a WFS 2.0 endpoint.

Query.spatialFilter and the deprecated source-native Query.where migration member compile to FES 2.0; GeoJSON is preferred over GML via OperationsMetadata negotiation. applyEdits() builds <wfs:Transaction> bodies. Reach Source.protocol("wfs") for raw GML, custom FES filters, GetPropertyValue, raw <wfs:Transaction> bodies, and stored queries.

Locking (LockFeature / GetFeatureWithLock) has no typed helper anywhere in the SDK. Callers that need locks must send their own request XML through Source.protocol("wfs")!.root.requestText(...) and parse the response themselves; no lock id is extracted and no lock state is tracked.

FES spatial predicates and transaction geometry name the feature type's geometry property, which is server-specific (the_geom on PostGIS-via-GeoServer, msGeometry on MapServer, arbitrary per-schema names elsewhere). The adapter resolves it from DescribeFeatureType on first use and caches it; locator.geometryName pins it explicitly. Resolution failure fails closed rather than guessing a default that would silently match nothing.

const dataset = createDataset({

    locator: { url: "https://your-honua-server.example/wfs", typeName: "ns:Parcels" },
    capabilities: PROTOCOL_DEFAULT_CAPABILITIES.wfs,
  }],
});
const result = await dataset.source("parcels")!.queryAll({
  pagination: { limit: 500 },
});
