Decoupling Drupal From Its Frontend System to Use in an Existing Website

The ability to create and publish content in real-time without knowing HTML or the ability to program is a common feature of many websites. This capability allows individuals to produce web content regardless of their technical ability. Producing web content is a common feature of many content management systems (CMS). Some websites don't allow direct creation and publication of content, so a possible solution to address this shortcoming is integrating a CMS into these websites. This article describes how Drupal, a CMS, was added to an existing Symfony website to allow users to publish content in real-time. Implementation details about integrating Drupal into the existing website using Headless Drupal are shared.
