Altenate route provided by postlight (api-routes.php) using slug: http://www.bubs.loc/wp-json/postlight/v1/page/?slug=sample-page

• Additionally , files that turn the theme to a "headless one" (one focusing on providing json api data of posts, acf, ... have been added (commented out with instructions).
