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

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 such language features and APIs, you should include the polyfill shipped in @wordpress/babel-preset-default in your code.

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
);

Logs a message to notify developers about a deprecated feature.

	plugin: 'the earth',
	hint: 'You may find it beneficial to transition gradually.',
