Feature: #70583 - Introduced Icon API in JavaScript

Description

A JavaScript-based icon API based on the PHP API has been introduced. The methods getIcon() and getIcons() can be called in a RequireJS module.

When imported in a RequireJS module, a developer can fetch icons via JavaScript with the same parameters as in PHP. The methods getIcon() and getIcons() return Promise objects.

Importing

define(['jquery', 'TYPO3/CMS/Backend/Icons'], function($, Icons) {
});

Get icons

A single icon can be fetched by getIcon() which takes four parameters:

To use the fetched icons, chain the done() method to the promise.

// Get a single icon
Icons.getIcon('spinner-circle-light', Icons.sizes.small).done(function(spinner) {
	$toolbarItemIcon.replaceWith(spinner);
});
