Interface Access Control

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

Possible values are listed below.

Modifier Description
global The interface can be extended by another interface or used by a component in any namespace.
public The interface can be extended by another interface or used by a component within the same namespace only. This is the default access level.

A component can implement an interface using the implements attribute on the aura:component tag.
