Notification and WebSocket

The Notification functionality in Moqui Framework is a user and topic based publish/subscribe tool that can be used to push notifications to server code by direct topic subscription or client applications by WebSocket. Other interfaces for client applications could be built for anything you'd like but the current OOTB implementation for this is WebSocket based and meant for notifications, screen pops, etc in web-based client applications.

NotificationMessage (server side)

The NotificationMessage interface in the Moqui Framework API is the primary object for generating notifications for one or more users and with a specific topic. The topic for a Notification is an arbitrary string identifier to distinguish different types of messages so that listeners (server side or client side) can listen for just the topics they know how to handle.

To generate a message first use the ExecutionContext.makeNotificationMessage() method which returns a NotificationMessage object. On that object call methods as needed to set the topic, title, type (info, success, warning, danger), message (Map or JSON body), and specify the user(s) and/or user groups that should receive the notification. For example:

ec.makeNotificationMessage().topic("TestTopic").type("info").title("Test notification message")

In this example a notification is sent to all users (via the Moqui automatic 'ALL_USERS' userGroupId) with the topic "TestTopic" and a message body in a Map or String object called 'messageMapOrJsonString'.
