myuw-notifications

Getting started

Import the component as follows:

<!-- import the module -->
<script type="module" src="https://cdn.my.wisc.edu/@myuw-web-components/myuw-notifications@latest/myuw-notifications.min.mjs"></script>

<!-- fallback for browsers without ES2015 module support -->
<script nomodule src="https://cdn.my.wisc.edu/@myuw-web-components/myuw-notifications@latest/myuw-notifications.min.js"></script>

<myuw-notifications
  slot="myuw-notifications"
  limit="3"
  see-all-url="/"
>
  <span slot="myuw-notifications-empty">All caught up!</span>
</myuw-notifications>

Note: The evergreen "latest" version can be used for convenience, but in production settings it is recommended to use the latest release version specifically, and upgrade only after testing!

Displaying notifications

The component listens for the "myuw-has-notifications" custom event to tell it when there are notifications ready to display. You can use this event after fetching all notifications from a URL or to add a single notification to the list. Dispatch the event like so:

document.dispatchEvent(new CustomEvent('myuw-has-notifications', {
  bubbles: true,
  detail: {
    notifications: [yourNotificationsArray]
  }
});

Note: The component includes a CustomEvent polyfill for browsers that don't already support them

Minimum required properties

A single "notification" object must contain the following properties:

{
  "id": "",
  "title:" "",
  "actionButton": {
    "label": "",
    "url": ""
  }
}

Notes:

• The object corresponding to the notifications property MUST be an array, even if you're only displaying a single notification
• The component expects a data model similar to the one currently used in MyUW. Efforts to make this more generic or to allow adopters to establish their own data models are in progress.

Dismissing notifications

Users are able to remove notifications from the list by clicking a notification's "X" dismiss button. Removal from the DOM and from the component's list is handled automatically, but if you need to hook into the event for your own purposes (e.g. to trigger an analytics event), you can listen for the myuw-notification-dismissed event, like so:

document.addEventListener('myuw-notification-dismissed', (event) => {
  // The event passes a detail object with a single
  // property: "notificationId", which is the "id" value of
  // the dismissed notification
  var dismissedNotificationId = event.detail.notificationId;
  // Do what you want with this information!
}, false);

In addition, notifications can be dimissed by dispatching a myuw-notification-dismissed event with the field event.detail.dismissedFromOutside set to true, and event.detail.notificationId set to id of the notification you want to dismiss.

Configurable attributes

• see-all-url: If this optional attribute is provided, the component will display a "See all" link in the title row of the notifications list.
• limit: Limits the number of notifications displayed. If unset, notifications that exceed the height limit of the menu can be seen via scrolling.

Slots

• myuw-notifications-empty: Use this slot to insert markup you would like your users to see when there are no new notifications to view.
