Add the force:appHostable
interface to a Lightning component to
allow it to be used as a custom tab in Lightning Experience or Salesforce1.
Components that implement this interface can be used to create tabs in both Lightning Experience and Salesforce1.
Example Component
<!--simpleTab.cmp-->
<aura:component implements="force:appHostable">
<!-- Simple tab content -->
<h1>Lightning Component Tab</h1>
</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.
