react-browser-notifications

React component for the Javascript Notifications API. The Notifications API allows web pages to control the display of system notifications to the end user. These are outside the top-level browsing context viewport, so therefore can be displayed even when the user has switched tabs or moved to a different app. This component is supported in modern web browsers such as Chrome, Safari, Firefox, Opera, and Edge.

Methods

Once you have the reference of ReactNotifications by including the onRef={ref => (this.n = ref)} prop, you can call the below methods

// Returns true if the Notifications API is supported by the browser
this.n.supported()

// Triggers the browser notification
this.n.show()

// Close the notification, which is ID'ed by the tag prop
this.n.close(tag)

Properties

The ReactNotifications component accepts the following props

Name	Type	Req/Opt	Description
onRef	function	Required	This is required to reference the ReactNotifications component. Recommended: onRef={ref => (this.n = ref)}, where n is any variable name
title	string	Required	Title of the notification
body	string	Optional	Text to display in the body of the notification
icon	string	Optional	Link to image to be displayed as the icon
tag	string	Optional	Unique identifier for the notification. If this is not provided as a prop, an unique shortid is automatically generated for the notification
timeout	string	Optional	Indicates, in milliseconds, the duration for which the notification will remain displayed, if less than the default timeout. Default timeout is dependent on the browser (typically 4s or 5s). Maximum duration is the default timeout
interaction	boolean	Optional	Only available in Chrome. Setting this to true makes the notification remain displayed until the user interacts with the notification (clicks the Close button). timeout overrides interaction if both props are provided
onClick	function	Optional	Fired when the notification is clicked
