| 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 pop-up windows when you click or query a feature. |
| 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. |

layerDefinition properties
| Property | Details |
|---|---|
| definitionExpression | SQL-based definition expression string that narrows the data to be displayed in the layer. |
| definitionGeometry | An extent object used to filter features for StreamLayer. Only features that intersect the extent are displayed. |
