Basemap URLs - nixta/arcgis GitHub Wiki
Commonly Used Basemaps (Tiles, Reference Layers, WebMaps and Details Pages).
Some basemaps include one or more reference layers (for example, the "Light Grey Canvas" basemap has a "Labels" layer). If you are adding these layers explicitly (as opposed to using a WebMap ID to load them all at once), keep in mind that you may need to add more than one layer, and that you may want to add the reference layers on top of your own data layers.
