Bubble notifications



Bubble notifications is a JavaScript system developed as part of MediaWiki for displaying notifications on a web page.

Features

 * Multiple notifications: It can display multiple notifications at the same time.  Each can be closed independently.


 * Automatic closing: A notification can be configured to automatically close after a short period of time.  This is enabled by default, but individual features using this system may choose to disable it for specific notifications where needed.

This enables an improved user experience where one would otherwise cause old, incomplete, or duplicate notifications to be visible ([https://www.w3.org/TR/notifications/#tags-example example use cases])
 * Tagging: A notification can optionally be given a name (or "tag").  When a new notification is created with the same name as an older one that is still active, the older one is replaced with the new one.

API
The entry point for the bubble notifications is the   method. Some examples:

The format is:  , available options are:


 * – A boolean indicating whether the notification should automatically be hidden after shown or if it should persist.
 * – Number of seconds for timeout of auto-hide notifications.
 * – An optional string. When a notification is tagged only one message with that tag will be displayed.  Trying to display a new notification with the same tag as one already being displayed will cause the other notification to be closed and this new notification to open up inside the same place as the previous notification.
 * – An optional title for the notification. Will be displayed above the content, usually in bold.
 * – An optional string for the type of the message used for styling: Examples: "info", "warn", "error"
 * – A boolean indicating if the autoHide timeout should be based on time the page was visible to user or if it should use wall clock time.
