Message Stack

You are browsing documentation for an older version of Drupal, which is not supported any longer, and the information may not be correct. See current documentation for Contributed modules

Introduction

The message stack comprises three main modules: Message, Message Notify, and Message Subscribe.

The modules have been written with a pluggable architecture that supports customization and extensibility. Each module includes implementation examples that give a hint of the potential use cases and integration with other popular Drupal modules.

The modules' object oriented architecture make this suite well positioned to support Drupal 8 and beyond. A number of well known Drupal distributions such as Commerce Kickstart, Drupal Commons, ERPAL, and Open Atrium have already adopted the message stack and are a good place to see the versatility of these modules in action.

The basic components and dependencies of the message stack are shown below:
