VectorTileLayer

Class

This class allows you to load and display ArcGIS vector tile layers in a MapLibre map.

The VectorTileLayer class provides functionality for:

Loading and displaying vector tile layers from ArcGIS Online item IDs or feature service URLs.
Adding sources and layers to a MapLibre map.
Managing vector tile layer styles.
Managing vector tile layer visibility and opacity.

Use dark colors for code blocksCopy
import { VectorTileLayer } from '@esri/maplibre-arcgis';

// Add a vector tile layer from an ArcGIS item ID
const vectorLayer = await maplibreArcGIS.VectorTileLayer.fromPortalItem('e0b5e1aa287845d78b1dabd3223ebed1');
vectorLayer.addSourcesAndLayersTo(map);

// Add a vector tile layer from an ArcGIS vector tile service URL
const vectorLayer2 = await maplibreArcGIS.VectorTileLayer.fromUrl('https://vectortileservices3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Santa_Monica_parcels_VTL/VectorTileServer');
vectorLayer2.addSourcesAndLayersTo(map);

Constructors

constructor

Class Constructor

VectorTileLayer(options: IVectorTileLayerOptions): VectorTileLayer

Creates a new VectorTileLayer instance. You must provide either an ArcGIS item ID or a vector tile service URL. If both are provided, the item ID will be used and the URL ignored.

Use dark colors for code blocksCopy
import { VectorTileLayer } from '@esri/maplibre-arcgis';
const vectorLayer = new VectorTileLayer({url: 'https://vectortileservices3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Santa_Monica_parcels_VTL/VectorTileServer', authentication: "YOUR_ACCESS_TOKEN"});
await vectorLayer.initialize();
vectorLayer.addSourcesAndLayersTo(map);

Creating layers using the constructor directly is not recommended. Use the VectorTileLayer.fromUrl and VectorTileLayer.fromPortalItem static methods instead.

Parameters

`options`	IVectorTileLayerOptions	Configuration options for the vector tile layer. You must provide either an ArcGIS item ID or a vector tile service URL. If both are provided, the item ID will be used and the URL ignored.
