A plugin that makes Slick a first-class citizen of Play 2.x.

This module is about integrating Slick with Play Framework.

From the documentation:

The Play Slick module makes Slick a first-class citizen of Play. It consists of two features:

Integration of Slick into Play's application lifecycle. Support for Play database evolutions. Because Slick creates and manages both a connection pool and a thread pool, integrating Slick with Play boils down to ensure that all resources allocated by Slick are shutted down when a Play application is stopped (or reloaded).

The plugin has its own release cycle and therefore is not integrated into either core Play or Slick.
