Lightning Bundle Configurations Available in the Developer Console

Configurations make it easier to create a component or application for a specific purpose, like a Lightning page or Experience Builder site page, or a quick action or navigation item in Lightning Experience or Salesforce mobile app. The New Lightning Bundle panel in the Developer Console offers a choice of component configurations when you create an Aura component or application bundle.

Configurations add the interfaces required to support using the component in the desired context. For example, when you choose the Lightning Tab configuration, your new component includes implements="force:appHostable" in the <aura:component> tag.

Using configurations is optional. You can use them in any combination, including all or none.

The following configurations are available in the New Lightning Bundle panel.
Configuration Markup Description
Aura component bundle
Lightning Tab implements="force:appHostable" Creates a component for use as a navigation element in Lightning Experience or Salesforce mobile apps.
Lightning Page implements="flexipage:availableForAllPageTypes" and access="global" Creates a component for use in Lightning pages or the Lightning App Builder.
Lightning Record Page implements="flexipage:availableForRecordHome, force:hasRecordId" and access="global" Creates a component for use on a record home page in Lightning Experience.
Experience Builder Site Page (previously Lightning Communities Page) implements="forceCommunity:availableForAllPageTypes" and access="global" Creates a component that’s available for drag and drop in the Experience Builder.
