I have a visualforce page that using Lightning Out App to show aura component to Non Authentication user. And when I click the button to save record on Aura Component and the result return successfully then the visualforce page need to close on the browser tab.
I have check on this document about communication about Lightning component and Visualforce page. https://developer.salesforce.com/blogs/developer-relations/2017/01/lightning-visualforce-communication.html
But this one show an example using visualforce page in lightning component using iframe so I want to know is there any other suggestion for communicate between LC and visualforce page when using Lightning out app.
