Popup Monitor

Popup Monitor is a small utility to facilitate the monitoring of a popup window close action, which is especially useful for temporary popup windows (e.g. an authorization step).

Usage

A Popup Monitor instance offers an open function which accepts an identical set of arguments as the standard window.open browser offering. When the window is closed, a close event is emitted to the instance with the name of the closed window.

import PopupMonitor from '@automattic/popup-monitor';

const popupMonitor = new PopupMonitor();

popupMonitor.open( 'https://wordpress.com/', 'my-popup' );

popupMonitor.on( 'close', function ( name ) {
	if ( 'my-popup' === name ) {
		console.log( 'Window closed!' );
	}
} );

Methods

• open( url, name, features ): Proxies an identical call to window.open and begins to monitor the window open state.
• getScreenCenterSpecs( width, height ): A helper method for generating a feature (specification) string of a specific width and height at the center of the user's screen.
