Extending ConReg

Extension approach

The core extension seam is member lifecycle hooks fired from Member save and delete operations. For extension points with multiple, selectable, orderable implementations (pricing rules, mailing-list providers), ConReg uses Drupal plugins instead — see docs/development/plugins.md.

Example hook skeleton

<?php

use Drupal\conreg\Member;

function mymodule_convention_member_updated(Member $member): void {
  // Custom integration logic.
}

Design notes

• Prefer service injection in new code.
• Preserve hook argument type expectations used by existing submodules.
