Converting procedural Drupal hooks to OOP attributes involves replacing .module file implementations with #[Hook] attribute classes. This modern pattern enables maintainable, testable module code through clear separation of concerns in Drupal 11+.

Yes, you can use OOP hook patterns with Drupal 10 by implementing a LegacyBridge. This bridge maintains compatibility while allowing you to adopt the #[Hook] attribute pattern before upgrading to Drupal 11.

The #[Hook] attribute supports form alters, entity hooks, theme hooks, and event subscribers. These OOP patterns replace procedural implementations in .module files while providing clear separation of concerns.

Yes, PHP 8+ is required to use Drupal hook attributes because the #[Hook] attribute syntax relies on PHP 8 attribute features. You also need Drupal Core 10 or 11 for compatibility.

The best way to migrate existing module code to OOP hook patterns is to identify procedural hook implementations in .module files and convert them to #[Hook] attribute classes. Use a LegacyBridge for Drupal 10 compatibility during the transition.

Migrating from procedural .module hooks to OOP attribute patterns improves maintainability and testability of module code. The #[Hook] attribute approach provides clear separation of concerns compared to traditional procedural implementations.
