Drupal Entity Reference Integrity
drupal-entity-reference-integrity is a Drupal module focused on keeping entity references consistent across content. It aims to detect and prevent broken references when entities are deleted, updated, or otherwise changed, so related content doesn’t silently point to missing or invalid targets.
This is useful in content-heavy Drupal sites where references drive navigation, listings, or business logic. Integrity checks and cleanup reduce hard-to-debug edge cases and help keep editorial workflows dependable as content models evolve. If you want to explore the implementation, see View Code.
Technical takeaway: treat entity references as first-class data relationships. By enforcing validation or cleanup at the module level, you can keep reference integrity aligned with your content lifecycle, which makes downstream rendering and integrations more reliable.
