Once all registered callbacks are performed, the injector will be cleared.
Such feature currently we require the browser supporting WeakRef.
We offer both asynchronous and synchorized callback in customYtElements.whenRegistered, however, since _initializeProperties() and all other related layouting and rendering will be conducted immediately after component registration, synchorized callback is preferred.

Example 1:

// ==UserScript==
// @name         Testing
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @match        https://www.youtube.com/*
// @icon         https://www.google.com/s2/favicons?sz=64&domain=youtube.com
// @grant        none
// @run-at       document-start
// @require      https://greasyforks.org/scripts/465819-api-for-customelements-in-youtube/code/API%20for%20CustomElements%20in%20YouTube.js?version=1187694
// ==/UserScript==

(function () {
  'use strict';

  console.log('script started');
  customYtElements.whenRegistered('ytd-rich-grid-renderer', (proto) => {
    console.log('yt element is registered', proto.is);
    proto.calcElementsPerRow = () => 5;
  });

})();

Example 2

You might also check whether the injector function is garbage collected (GC) or not.


(function () {
  'use strict';

  console.log('script started');
  customYtElements.whenRegistered('ytd-rich-grid-renderer', (proto) => {
    console.log('yt element is registered', proto.is);
    proto.calcElementsPerRow = () => 5;
    if (typeof WeakRef === 'function') {
      console.debug('Is injector is cleared in memory? (#1)', proto._registered.__injector__.deref() === undefined);
      setTimeout(() => {
        console.debug('Is injector is cleared in memory? (#2)', proto._registered.__injector__.deref() === undefined);
      }, 5000);
    }
  });

})();
