1 Introduction

Lightbox plugins have been a staple of Drupal-powered websites for over a decade. They allow editors to display images, videos, and other media in an overlay without navigating away from the current page — a pattern visitors expect on modern, media-rich sites.

1. Why CI-Driven Configuration Management Matters

Drupal's configuration system is one of the platform's greatest strengths — and one of its most reliable sources of pain. The ability to export and import every piece of site configuration as YAML files is powerful, but only if everyone agrees on who is responsible for moving those files between environments. In most teams, that agreement never quite exists.

The classic problems are well-known to anyone who has shipped a Drupal site:

Although support for Drupal 7 has already ended and no new updates will be released, all new modules are now being published for Drupal 11+, there are still many websites running on Drupal 7 that are unable to migrate to newer versions. There are valid reasons for this, especially for sites with a large amount of custom code.

Why this change?

• In Drupal 9, jQuery Cookie was removed from core and replaced with the js-cookie library. A BC shim (core/jquery.cookie) existed during Drupal 9 but was removed for Drupal 10.

This section is about updating the Drupal core from previous versions (including legacy Drupal 6 and Drupal 7) to the latest stable release. I will also publish articles here on how to update contributed modules for Drupal.

The Drupal CKEditor module is ending support for CKEditor 4. However, you still have the option to connect CKEditor 4 through custom modules and continue using it. Of course, using the new CKEditor 5 or later is preferable, but the legacy CKEditor module is still used by more than 140,000 sites (every fourth Drupal site!):

Prompt for ChatGPT to Rewrite jQuery to JavaScript

If you want to rewrite jQuery code into pure JavaScript using ChatGPT, navigate to chat.openai.com and enter the following clear, concise prompt:

Please rewrite the following jQuery code into vanilla JavaScript, maintaining the same functionality. Ensure compatibility with modern JavaScript standards (ES6+). Also, include usage of Drupal.behaviors if applicable. [Paste your jQuery code here]

I have huge number of configs and run usually config import with php -d memory_limit=-1 (disable memory limit for PHP):

 php -d memory_limit=-1 ./vendor/bin/drush config-import -y

But this time I got an error:
