Questions tagged [lightning-out]

Lightning Out is a feature that allows Lightning Components to be used in pages that are run from non-Salesforce servers allowing components to be added to external apps. A JavaScript library is included in the page on the origin server. Markup is added to configure & activate the Lightning components app. Lightning Out pulls the components app into the page over a secure connection & inserts it into the DOM of the page.
