System Tag Reference

System tags represent framework definitions and are not available in the Component Library.

• aura:application

  An app is a special top-level component whose markup is in a .app resource.

• aura:dependency

  The <aura:dependency> tag enables you to declare dependencies, which improves their discoverability by the framework.

• aura:event

  An event is represented by the aura:event tag, which has the following attributes.

• aura:interface

  Interfaces determine a component’s shape by defining its attributes. Implement an interface to allow a component to be used in different contexts, such as on a record page or in Lightning App Builder.

• aura:method

  Use <aura:method> to define a method as part of a component’s API. This enables you to directly call a method in a component’s client-side controller instead of firing and handling a component event. Using <aura:method> simplifies the code needed for a parent component to call a method on a child component that it contains.

• aura:set

  Use <aura:set> in markup to set the value of an attribute inherited from a component or event.
