Configure Components for Custom Tabs

Add the force:appHostable interface to an Aura component to allow it to be used as a custom tab in Lightning Experience or the Salesforce mobile app.

Components that implement this interface can be used to create tabs in both Lightning Experience and the Salesforce app.

Example Component

1<!--simpleTab.cmp-->
2<aura:component implements="force:appHostable">
3
4    <!-- Simple tab content -->
5
6    <h1>Lightning Component Tab</h1>
7
8</aura:component>

The appHostable interface makes the component available for use as a custom tab. It doesn’t require you to add anything else to the component.
