OOP, Design Patterns and Drupal 8
summary
A custom Drupal 8 module on GitHub implements a presentation_manager service that builds a table of contents, provides getPrevious/getNext slide methods, and powers two configurable blocks (one a context-aware plugin that pulls node images) using dependency injection against the entity_type.manager interface. Routing files map URLs to controller methods (one loaded into the modal API), a table of contents trait lets a controller and block share build logic, libraries YAML loads a small JS, and Twig template suggestions attach the library — everything runs in the demo.
