A Flarum extension. Guests Online widget
Currently, guests are only calculated when using the Flarum default session driver (files). I might consider adding support for database, redis, etc in future. Let me know if you're interested in sponsoring any of these additions.
This will also install Forum Widgets Core as it relies on it.
Install with composer:
composer require ianm/online-guests:"*"composer update ianm/online-guests:"*"
php flarum migrate
php flarum cache:clear
