Use Cases

A use case is a specific functionality that the application provides. This can be exposed through a controller to the outside world. Or it can be used internally by other use cases, jobs, cronjobs, etc.

Module

We create a module in each use case folder to keep the codebase clean and organized. This module imports the necessary dependencies for the use case.

@Module({
  imports: [
    TypeOrmModule.forFeature([User]),
  ],
  controllers: [GetUserController],
  providers: [GetUserUseCase],
  exports: []
})
export class GetUserModule {}
