DotKernel is a collection of

PSR-7 Middleware applications

built on top of Zend Expressive microframework.
It is composed of a set of custom and extended Zend Framework components.


Zend Expressive


DotKernel is built around the PSR-11 dependency container. We have chosen Zend Service Manager as our default implementation.

By default, no middleware in Expressive is templated. For DotKernel's Frontend application, we have chosen Twig as the default templating engine.

Among the various routing implementations compatible with Expressive, we have chosen FastRoute as DotKernel's default routing library.

Expressive, and consequently DotKernel is built around the PSR-7 standard. It uses Zend Diactoros as the PSR-7 implementation.
