CreateUserUsecase

Purpose

Executes this business operation according to domain rules implemented in the use case.

Trigger / entry point

  • Internal invocation through dependency injection (Inversify).

Inputs

Name Required Type Description
dto Yes object Use case input DTO (see implementation file).

Preconditions

  • Input DTO must respect constraints enforced by the implementation.
  • Caller context/authorization must satisfy business checks implemented in the use case.

Main flow

  1. Validates input/access constraints defined in execute and helper guards.
  2. Uses bddService dependency to read/write required domain data.
  3. Uses cryptService dependency to read/write required domain data.
  4. Initializes a coach subscription when initialSubscriptionPlanCode is provided for a newly created coach.

Outputs / side effects

  • Returns the use case result (entity/model/list or boolean depending on implementation).
  • May persist domain state changes through repository/service dependencies.
  • Logs execution errors through the logger service before normalization/rethrow.

Error cases / edge cases

  • Throws ERRORS.CREATE_USER_USECASE_USER_ALREADY_EXIST when repository reports an existing email.
  • Normalizes or references error code ERRORS.CREATE_USER_USECASE.

Dependencies

  • bddService
  • cryptService
  • initializeCoachSubscriptionUsecase
  • loggerService

}

Notes / limitations

  • This document is generated from code and should be updated whenever behavior changes in implementation.
  • If helper modules define additional rules, they are authoritative over this summary.
