CORS_URL for HEROKU is only used for so-called social-feed-server. This component is not finalized and not ready for any use. Social-feed-server is not needed for the regular social-feed. Social-feed is front-end only component and it does not require back-end.
If you still intend to use specifically this component, CORS_URL is url of the website from which you plan to make cross domain requests to the server side.
