New Experiment: Optimized Asset Loading Mode

In the upcoming Elementor v3.1.0, we created a new “Improved Asset Loading” mode, which reduces the amount of JS code loaded on the page by default. When activated, parts of the infrastructure code will be loaded asynchronously, only when needed.

Which Functionalities Already Support the New Improved Asset Loading Mode?

1. Widget JS Handlers

Up to Elementor v3.1.0, all widget handlers were loaded to every page by default, regardless of whether they are actually used on the page.

Starting in Elementor v3.1.0, when the “Improved Asset Loading” mode is active, each widget will dynamically load its handler, only when being used on the page.

A New Method For Attaching A JS Handler To An Element

In Elementor 3.1.0 version, we created a new method for attaching a JS handler to an element.

Up to Elementor 3.1.0, in order to attach a JS handler, we used a hook called addAction, and passed a function to it (addHandler):

const addHandler = ( $element ) => {
	elementorFrontend.elementsHandler.addHandler( ElementHandlerClass, {
	} );
elementorFrontend.hooks.addAction( 'frontend/element_ready/your-element-name.default', addHandler );
