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

By default, no middleware in Mezzio is templated. We use Twig as the default templating engine.

There are various routing implementations compatible with Expressive. We have chosen FastRoute as Dotkernel’s default routing library.

Mezzio, and consequently Dotkernel, is built around PSR-7. It uses Laminas Diactoros as the PSR-7 implementation.
