Live configuration
A dialog in the live configuration ("Map" → "Contents") lets you add layers (also called map services, operational layer or thematic maps) and basemaps (also called base maps or background maps) by using a URL.
You can switch between the different sections using the "Layers" and "Basemaps" tabs. To open a dialog for adding another map, click Add map.
Enter the URL of an ArcGIS map service (…/MapServer), an ArcGIS feature layer (for example …/FeatureServer/0) or a WMS.
To determine type, title and description, click Query metadata.
Select a map in the list, to display further information. Select Activated on app startup. to show this app when the app is started.
The symbol to the right of the individual maps can be used to change the order of the maps or to remove the map from the configuration.
The steps described preceding apply to both layers and basemaps. For the basemaps, only one map can be activated at a time when starting the app.
Manual configuration
Basemaps
Use the parameter "selected": true to define the basemap that is activated at the start of an app.
Esri basemaps
Basemaps from Esri can be used by fixed IDs. To do this, enter one of the Esri basemap IDs .

For more information about the parameters, see the documentation for the WMTS Layer in the ArcGIS API for JavaScript.
Multiple basemaps
To provide the capability to switch between different basemaps, several basemaps can be configured in one app.
{
"map-init": {
"Config": {
"basemaps": [
{
"id": "streets",
"title": "Streets",
"selected": true,
"basemap": "streets-vector"

}
}Combination of maps into one basemap
With the help of the following configuration two maps can be combined to a basemap. For the user only one entry appears in the app.
{
"map-init": {
"Config": {
"basemaps": [
{
"id": "combined",
"title": "Grundkarte",
"basemap": {
"type": "GROUP",
"layers": [
{
"type": "AGS_VECTORTILE",
"url": "https://www.arcgis.com/sharing/rest/content/items/6f65bc1351b7411588a8cb43fe23dad7/resources/styles/root.json"
},
{
"type": "AGS_TILED",
"url": "https://services.arcgisonline.com/arcgis/rest/services/Elevation/World_Hillshade/MapServer"
}
]
},
"selected": true
}
],
"map": {}
}
}
}With the following configuration, the map is changed at a scale of 1:1,000,000.
{
"map-init": {
"Config": {
"basemaps": [
{
"id": "combined",
"title": "Grundkarte",
"basemap": {
"type": "GROUP",
"layers": [
{
"type": "AGS_TILED",

"maxScale": 1000000
}
]
},
"selected": true
}
],
"map": {}
}
}
}Layers
Thematic maps are displayed above basemaps.
Their configuration is similar to that of the basemaps, but the parameter "selected": true does not exist for thematic maps.
Instead, the parameter "visible": true or "visible": false can be used to determine whether the map or layer is visible when the app is started.

Initial view
Required Bundle: map-init
To set the view that is displayed when an app starts, you can use the Live configuration. Open the section Map → Initial View. Change the map or 3D scene to the view that you want to display when the app starts. You can close the configuration window in between. To reopen it to save the setting, click Live configuration again.
Alternatively, the values can be set in the manual configuration:
{
"map-init": {
"Config": {
"map": {},
"view": {
"viewmode": "2D",
"scale": 328083,
"center": {
"x": 803388,
"y": 6604631,
"spatialReference": {
"wkid": 3857
}
}
}
}
}
}{
"map-init": {
"Config": {
"map": {},
"view": {
"viewmode": "3D",
"camera": {
"heading": 338.0030989113829,
"tilt": 77.24010183113229,
"position": {
"x": 795277.8187824533,
"y": 6569001.517765303,

"spatialReference": {
"wkid": 102100
}
}
}
}
}
}
}|
Switch view between 2D and 3D
The bundle viewmodeswitcher provides a tool to change the view within an app between 2D and 3D.

ArcGIS web maps and web scenes
Required Bundle: portal-webitem-map
map.apps can load web maps or web scenes from Portal for ArcGIS or ArcGIS Online. The full configuration is taken directly from web map or scene and an additional map configuration is not required inside the app.
To add an element, the section "ArcGIS Online and Portal for ArcGIS" → "ArcGIS Web Maps and Web Scenes" can be used in the live configuration. A simplified search for elements is available in this dialog.
Alternatively, the values can be set in the manual configuration.
{
"portal-webitem-map": {
"Config": {
"portalItem": {
"id": "31874da8a16d45bfbc1273422f772270",
"portal": "https://myserver/arcgis"
}
}
}
}If the portal URL parameter is ommitted, the element is loaded from the Portal for ArcGIS defined in the configuration.
