Properties

Property Details
blendMode Blend modes are used to create various effects by blending colors of top and background layers. normal blend mode is the default.
Valid values: average, color, color-burn, color-dodge, darken, destination-atop, destination-in, destination-out, destination-over, difference, exclusion, hard-light, hue, invert, lighten, lighter, luminosity, minus, multiply, normal, overlay, plus, reflect, saturation, screen, soft-light, source-atop, source-in, source-out, vivid-light, xor
disablePopup Indicates whether to allow a client to ignore popups defined by the service item.
id A unique identifying string for the layer.
itemId Unique string value indicating an item registered in ArcGIS Online or your organization's portal.
layerDefinition An object that defines the attribute schema and drawing information for a layer drawn using client-side graphics.
See layerDefinition properties table.
layerType String indicating the layer type.
Valid value of this property WFS
maxScale A number representing the maximum scale at which the layer will be visible. The number is the scale's denominator.
minScale A number representing the minimum scale at which the layer will be visible. The number is the scale's denominator.
mode Number where 0 means 'snapshot' and 1 means 'ondemand'.
opacity The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency.
popupInfo A popupInfo object defining the content of popup windows when you click or query a feature.
refreshInterval Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled.
showLabels Labels will display if this property is set to true and the layer also has a labelingInfo property associated with it. This property can get stored in the web map config and in the item/data.
showLegend Indicates whether to allow map authors the ability to control what layers should be shown in a client's legend.
title A user-friendly string title for the layer that can be used in a table of contents.
url The URL to the layer. If the layer is not from a web service but rather a feature collection, than the url property is omitted.
visibility Boolean property determining whether the layer is initially visible in the web map.
wfsInfo Object that defines and provides information about layers in a WFS service.

layerDefinition properties

Property Details
definitionExpression SQL-based definition expression string that narrows the data to be displayed in the layer.
drawingInfo Contains the drawing and labeling information.
featureReduction Feature reductions declutter the screen by hiding features that would otherwise intersect with other features on screen.
fields An array of field objects containing information about the attribute fields for the feature collection or layer.
geometryType A string defining the type of geometry. Possible geometry types are: esriGeometryPoint, esriGeometryMultipoint, esriGeometryPolyline, esriGeometryPolygon, and esriGeometryEnvelope.
spatialReference An object containing the WKID or WKT identifying the spatial reference of the layer's geometry.
