Notification creator

Title (title) Defines a title for the notification, which is shown at the top of the notification window.

Direction (dir)

The direction in which to display the notification. It defaults to auto, which just adopts the browser's language setting behavior, but you can override that behaviour by setting values of ltr and rtl (although most browsers seem to ignore these settings.)

auto Let device determine automatically. (default) ltr Left-to-right. rtl Right-to-left.

Language (lang) The notification's language, as specified using a DOMString representing a BCP 47 language tag.

Learn more about BCP 47 language tags. See the Sitepoint ISO 2 letter language codes page for a simple reference.

Badge image URL (badge) A USVString containing the URL of the image used to represent the notification when there isn't enough space to display the notification itself. Body text (body) A DOMString representing the body text of the notification, which is displayed below the title. Identifying tag (tag) A DOMString representing an identifying tag for the notification. Icon image URL (icon) A USVString containing the URL of an icon to be displayed in the notification. Image URL (image) A USVString containing the URL of an image to be displayed in the notification. Notify again? (renotify) A Boolean specifying whether the user should be notified after a new notification replaces an old one. The default is false, which means they won't be notified. Do not close automatically. (requireInteraction) A Boolean specifying whether the user should be notified after a new notification replaces an old one. The default is false, which means they won't be notified. Do not close automatically. (silent) A Boolean specifying whether the notification is silent (no sounds or vibrations issued), regardless of the device settings. The default is false, which means it won't be silent.

Descriptions of each field were taken from MDN. They used to have documentation for the DOMString, USVString,and Boolean types, but it seems some of them have since been removed, probably because they were confusing.
