How can I get the current user role in my web app? I'm working on web app with a Drupal 8 back-end which is accessed by the D8 REST API.  I need to get the current user role so I can manage some options by role. Is there an existing REST route for getting the role and/or ID of the currently authenticated user.  I've had success with other REST routes like http://example.com/drupal/user/1?_format=hal_json, but this returns the user with id=1. What i'd like is http://example.com/cms/user/me?_format=hal_json
Any suggestions?
I have just used views to get this working.

Duplicate the default people view and rename it current_user.
Add a rest export route eg. rest/users/current_user.
Add a filter for current user. (User: Current = yes)
Save all.
Retrieve the current user via http get request on example.com/rest/user/current_user?_format=hal_json

Thanks to QueenVictoria for the advice.
