How to create custom singleton service and inject to other services?

[srindom]

We have creation of custom services documented here: https://docs.medusajs.com/advanced/backend/services/create-service

In your Medusa project you can place a file at /src/services/cool-stuff.js that default exports a service.

This service will automatically be registered in Medusa's dependency container as coolStuffService.

To use it in other services you would do something like:

class SomeService {
  // ...
  constructor({ coolStuffService }) {
    // ...
  }
}

To use it in an endpoint controller you can do:

const coolStuffService = req.scope.resolve("coolStuffService`)
