Return ajax_page_state['libraries'] via a header

Open on Drupal.org →
Created on 12 November 2024, 22 days ago

Problem/Motivation

We currently follow the existing pattern in core in which drupalSettings.ajaxPageState.libraries is returned with each request as a query parameter. The works to keep the asset libraries in sync. However, in core only automated processes see these urls. With HTMX if hx-push-url is used with true the url of the request is pushed to the location bar.

Proposed resolution

Given the work done in 📌 Compress ajax_page_state Fixed , move the transmission of page state from a query parameter to a header. The compression should keep this string well within the 8K bytes (8K UTF-8 characters) limit imposed by the most common web servers.

Refactor htmxDrupalPageState to place drupalSettings.ajaxPageState.libraries in an HX-Page-State header.
Refactor HtmxResponseAttachmentsProcessor::processAssetLibraries to begin with code to process the header. Just before this method is called the parent runs

$ajax_page_state = $this->requestStack->getCurrentRequest()->get('ajax_page_state');
$assets->setAlreadyLoadedLibraries(isset($ajax_page_state) ? explode(',', $ajax_page_state['libraries']) : []);
