retrieve user context from service layer

How can I directly retrieve user information in my service layer?

// Something like that:
const user = getSecurityContext().authenticatedUser()

If I am on the Controller Layer I would use:

@Post()
  create(@AuthenticatedUser() user: any, @Body() createArticleDto: CreateArticleDto) {
    this.logger.debug(`create user now`, user);
    return this.articlesService.create(user, createArticleDto);
  }

But then I need to pass it down to all my services…

Is there a better way to do it?

Thanks for the additional code and sorry if I wasn’t clear.

I do have access to the user instance inside the Controller layer because AuthGuard is in my module. I was just trying to avoid passing down the user from Controller Layer to Service Layer. Having access to the request makes it possible to parse the token in the Service Layer (as per provided code) but it is inefficient since it was already parsed in the controller layer and I thought there would be another way to re-use it.

I will read more on cls-hooked.
