An Adapter provides a way to extend the functionality of Fusio. It is i.e. possible to connect to different data sources or extend specific capabilities of the system. The following page lists available adapters. You can install an adapter through composer and then register the adapter class at the system:
composer require fusio/adapter-mongodb
php bin/fusio system:register "Fusio\Adapter\Mongodb\Adapter"
This page lists all adapters which have the keyword fusio-adapter
in their composer json file.
