@wordpress/deprecated

Deprecated

Deprecation utility for WordPress. Logs a message to notify developers about a deprecated feature.

Installation

Install the module

npm install @wordpress/deprecated --save

This package assumes that your code will run in an ES2015+ environment. If you're using an environment that has limited or no support for ES2015+ such as lower versions of IE then using core-js or @babel/polyfill will add support for these methods. Learn more about it in Babel docs.

Hook

The deprecated action is fired with three parameters: the name of the deprecated feature, the options object passed to deprecated, and the message sent to the console.

Example:

import { addAction } from '@wordpress/hooks';

function addDeprecationAlert( message, { version } ) {
	alert( `Deprecation: ${ message }. Version: ${ version }` );	
}

addAction( 'deprecated', 'my-plugin/add-deprecation-alert', addDeprecationAlert );
