Hi, I'm Dao Duc Trung.

I originally developed this module to solve a specific need for my website, ddt.one: notifying users via email when content they have "flagged" (bookmarked, subscribed, etc.) gets updated. While it was built for my personal use case, I believe it provides a solid foundation for anyone needing similar functionality in Drupal 11, so I released it publicly.

Flagger Notify integrates with the Flag module to send automated email notifications to users when a node they have flagged is updated.

• Queue-Based Processing: Notifications are added to a queue and processed via Cron, ensuring performance is not impacted during content updates.
• Smart Debounce: If a node is edited multiple times in a short period, only one notification is queued per cycle.
• Per-Flag Configuration: Set different email templates for different flags (e.g., "Bookmark" vs "Follow").
• Translation Ready: Fully translatable configuration for multilingual sites.
• Access Control: Respects node permissions. If a user loses access to view a node (e.g., it is unpublished), they will silent skip receiving the notification.
• Debug Mode: detailed logging of queue operations and email content (including raw HTML) for testing.

• Drupal Core: ^11
• Flag module
• Token module
• User module (Drupal Core) - Required for user notifications.

1. Place the module structure in your modules/custom directory.
2. Enable via Drush:

   drush en flagger_notify

3. Ensure dependencies are installed.

1. Go to Configuration > System > Flagger Notify (/admin/config/system/flagger-notify).
2. Global Defaults: Set a fallback email subject and body.
3. Flags: Check the flags you want to enable. You can then override the email subject/body for that specific flag, or leave it empty to use the global default.
4. Tokens: Use the Token browser to insert dynamic values (e.g., [node:title], [user:display-name], [node:url:absolute]).
