Architectural Modules

Medusa's architectural functionalities, such as emitting and subscribing to events or caching data, are all implemented in architectural modules. An architectural module is a package that can be installed and used in any Medusa application. These modules allow you to choose and integrate custom services for architectural purposes.

For example, you can use our Redis Event Module to handle event functionalities, or create a custom module that implements these functionalities with Memcached. Learn more about Medusa's architecture in this documentation.

This section of the documentation showcases official architectural modules and how to configure them in your application.
