Drupal, Decoupled Architecture
Evoluzione Enterprise senza ‘Big Bang’: lo Strangler Fig Pattern con Drupal
Rebuilding a Drupal portal from scratch takes months before it starts delivering value, and it concentrates all the risk into a single night’s release. At DrupalCamp Italy 2026 Adriano Cori presented the alternative we apply with the Strangler Fig Pattern, an incremental replacement in which the new Next.js frontend runs alongside Drupal on the same domain and replaces its theme one family of pages at a time. Each family of pages can be switched back to Drupal with a configuration change.
He also showed the limits of the method and the cases where decoupling is not needed. The Page Delivery modules, which we use to apply it, have been open source on drupal.org since 22 October 2026.
The Insight ‘Migrazione incrementale con Strangler Fig Pattern: disaccoppiare Drupal senza fermare il business’ explains how the coexistence works and which checks come before each family of pages is moved.
