Help implementing Slim

[NotionCommotion]

How can I get rid of the Factory class and instead put in in closure, and shorten $this->get('Factory')->get('Accounts')->read()) to something like $this->factory('Accounts')->read())?

 

Also, please provide constructive criticism of the below code other than my preliminary user authentication and logoff.

 

Thank you
