Module Description

This module is a generic interface for event pushing backends. It defines a single hook, push_event/3 that forwards the event to all registered backends. Each backend decides how and if to handle the event in its push_event/2 implementation.

The events are standardized as records that can be found in mod_event_pusher_events.hrl file. Common events like user presence changes (offline and online), chat and groupchat messages (incoming and outgoing) are already hooked up to the frontend via mod_event_pusher_hook_translator which is a proxy between various hooks and push_event/3 hook handler.


  • backends (required, list) - Specifies backends to register with the frontend, along with arguments that will be passed to the backend. Currently supported backends include sns, push and http_notification. Refer to their specific documentation to learn more about their functions and configuration options.
