Introduction

The MagicMirror core has the ability to send notifications to modules. Or even better: the modules have the possibility to send notifications to other modules.

Additional technical information on the notifications can be found in the modules' documentation:

System notifications

The system sends three notifications when starting up:

Notification	Payload	Description
`ALL_MODULES_STARTED`	none	All modules are started. You can now send notifications to other modules.
`DOM_OBJECTS_CREATED`	none	All dom objects are created. The system is now ready to perform visual changes.
`MODULE_DOM_CREATED`	none	This module's dom has been fully loaded. You can now access your module's dom objects.
`MODULE_DOM_UPDATED`	none	This module's dom has been updated and re-rendered. You can now access your module's (updated) dom objects. This notification is sent in response to a call to `updateDom`.

Default module notifications

These notifications are sent by the default modules:

Take a look in the wiki to see if 3rd party modules send notifications you might want to use.
