# Notification

The Notification module includes a toolkit for defining notification templates and supports sending notifications through multiple channels, such as Gmail and in-app messaging. It also has the capability to store sent notifications for future reference.

The Notification plugin includes the following components:

• Notification Class: Defines the blueprint used to create specific notification objects.
• Notifier: The Notifier is the component responsible for sending notifications. It understands how to deliver notifications into a channel
• Channel: This specifies how the notification is delivered. Common channels include email, push notification, or in-app message.

Each channel includes the following components:

• Message: The final object obtained after successful data binding is used by the Notifier Channel
• Template Context: This provides details specific to the notification instance. This might be user information, order details, etc

The channel is composed of two main components:

• Template Entity: This represents the data structure containing the notification content.
• Service: This handles the logic of sending notifications, including triggering the template engine.

You may configure the settings to install plugin.
