It provides a set of HTTP helpers, middlewares, routes, controllers, models, etc; besides being able to handle Dependency Injection thanks to PHP-DI. I have used some different libraries, most of them from Symsonfy Framework and League. The router system works using League\Route, which is a router system made on top of Nikita Popov's Fast Route, and HTTP request and response, as long as other PHP globals are used within Zend Diactoros, based on PSR-7. The template engine is handled by Twig. I don't use Session vars neither store session-cookies, because for future integration I preferred using JWT approach to store session data. Hope you enjoy using it!
