The Locate component animates the Map or Scene to the user's current location.

This component uses the browser's Geolocation API which is only available in secure contexts, such as HTTPS. Note that localhost is considered "potentially secure" and can be used for easy testing in browsers that support Window.isSecureContext.

autoDestroyDisabled

Property
autoDestroyDisabled: boolean

If true, the component will not be destroyed automatically when it is disconnected from the document. This is useful when you want to move the component to a different place on the page, or temporarily hide it. If this is set, make sure to call the destroy method when you are done to prevent memory leaks.

Attribute
auto-destroy-disabled
Default value
false

geolocationOptions

Property

goToLocationDisabled

reflected
Property
goToLocationDisabled: boolean

Indicates whether to navigate the view to the position and scale of the geolocated result.

Attribute

goToOverride

Property
goToOverride: (((view: MapView | SceneView, goToParameters: GoToParameters) => void))

graphic

Property
graphic: Graphic

The graphic used to show the user's location on the map.

Attribute

referenceElement

Property

By assigning the id attribute of the Map or Scene component to this property, you can position a child component anywhere in the DOM while still maintaining a connection to the Map or Scene.

Attribute

scale

Property
scale: number

Indicates the scale to set on the view when navigating to the position of the geolocated result, after a location is returned from the track event.

Attribute
scale
Default value
null

state

reflected
Property
state: "disabled" | "error" | "feature-unsupported" | "locating" | "ready"

The current state of the component.

Attribute
state

view

Property

The view associated with the component.

Note: The recommended approach is to fully migrate applications to use map and scene components and avoid using MapView and SceneView directly. However, if you are migrating a large application from widgets to components, you might prefer a more gradual transition. To support this use case, the SDK includes this view property which connects a component to a MapView or SceneView. Ultimately, once migration is complete, the Locate component will be associated with a map or scene component rather than using the view property.
