Medusa and Module Container Resources

This reference provides the list of resources registered in the Medusa container and module containers.

Medusa Container Resources#

The following table lists all resources that you can resolve in your customizations outside a module (such as API routes, workflows, subscribers, and scheduled jobs).

Note: Refer to the Medusa Container documentation for more information on how to use these resources.

Tip: You can use the ContainerRegistrationKeys enum imported from @medusajs/framework/utils where specified.

Resource	Description	Registration Name
Medusa Configurations	The configurations defined in `medusa-config.ts`.	`configModule` or `ContainerRegistrationKeys.CONFIG_MODULE`
Logger	Utility to log messages to the terminal.	`logger` or `ContainerRegistrationKeys.LOGGER`
Query	Query to retrieve data across modules.	`query` or `ContainerRegistrationKeys.QUERY`
Link	Manage links between records of two modules' data models.	`link` or `ContainerRegistrationKeys.LINK`
Modules' main services	The main service of every module added in `medusa-config.ts`.	For custom modules, the registration name is the first parameter of `Module` exported in the `index.ts` file of the module. For Medusa's Commerce and Infrastructural Modules, use the `Modules` enum imported from `@medusajs/framework/utils`.

Module Container Resources#

The following table lists all resources that you can resolve in a module's services or loaders.

Note: Refer to the Module Container documentation for more information on how to use these resources.

Note: Use the ContainerRegistrationKeys and Modules enums imported from @medusajs/framework/utils where specified.

Resource	Description	Registration Name
Logger	Utility to log messages to the terminal.	`logger` or `ContainerRegistrationKeys.LOGGER`
Entity Manager	An instance of MikroORM's entity manager.	`manager` or `ContainerRegistrationKeys.MANAGER`
Base Repository	An instance of the base repository, used to run transactions and perform database operations.	`baseRepository`
Medusa Configurations	The configurations defined in `medusa-config.ts`.	`configModule` or `ContainerRegistrationKeys.CONFIG_MODULE`
Event Module's service	The service of the Event Module, used to emit events.	`event_bus` or `Modules.EVENT_MODULE`
Services generated by the service factory	The service of every data model passed to the `MedusaService` function that your module's service extends. The service has the methods described in the service factory reference.	Each service is registered as the camel-cased name of the data model. For example: `Brand` data model's service is registered as `brandService`. `DigitalProduct` data model's service is registered as `digitalProductService`.
Module services	You can resolve the module's services from one another, but not in loaders. Learn more in the Module Container documentation.	Each service is registered as the camel-cased name of the service. For example: `BrandModuleService` is registered as `brandModuleService`. `CmsService` is registered as `cmsService`.
