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.


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

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

    alternative: 'vegetables',
    plugin: 'the earth',
    hint: 'You may find it beneficial to transition gradually.',
} );
