Component Access Control

The access attribute on the aura:component tag indicates whether the component can be extended or used outside of the component’s namespace.

Possible values are listed below.

Modifier Description
global The component can be used by another component or application in any namespace. It can also be extended in any namespace if extensible="true" is set on the aura:component tag.
public The component can be extended or used by another component, or used by an application within the same namespace only. This is the default access level.

Components aren’t directly addressable via a URL. To check your component output, embed your component in a .app resource.
