Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
@ckeditor/ckeditor5-utils
Advanced tools
@ckeditor/ckeditor5-utils is a utility library for CKEditor 5 that provides a variety of helper functions and classes to facilitate common tasks such as DOM manipulation, event handling, and data structures.
Event Handling
The EmitterMixin class allows you to add event handling capabilities to your classes. In this example, we create a class that extends EmitterMixin, instantiate it, and then set up an event listener for 'myEvent'. When 'myEvent' is fired, the listener logs a message to the console.
const { EmitterMixin } = require('@ckeditor/ckeditor5-utils');
class MyClass extends EmitterMixin() {}
const myInstance = new MyClass();
myInstance.on('myEvent', () => {
console.log('myEvent was fired!');
});
myInstance.fire('myEvent');
DOM Manipulation
The createElement function simplifies the process of creating and configuring DOM elements. In this example, we create a <div> element with a class and id, and then append it to the document body.
const { createElement } = require('@ckeditor/ckeditor5-utils');
const div = createElement(document, 'div', {
class: 'my-class',
id: 'my-id'
});
document.body.appendChild(div);
Data Structures
The Collection class provides a way to manage a collection of items. In this example, we create a new collection, add items to it, and then retrieve an item by its id.
const { Collection } = require('@ckeditor/ckeditor5-utils');
const collection = new Collection();
collection.add({ id: 1, name: 'Item 1' });
collection.add({ id: 2, name: 'Item 2' });
console.log(collection.get(1)); // { id: 1, name: 'Item 1' }
Lodash is a popular utility library that provides a wide range of functions for common programming tasks such as manipulating arrays, objects, and strings. Compared to @ckeditor/ckeditor5-utils, Lodash offers a broader set of utilities but does not include CKEditor-specific features like event handling and DOM manipulation.
jQuery is a fast, small, and feature-rich JavaScript library that simplifies HTML document traversal and manipulation, event handling, and animation. While jQuery offers powerful DOM manipulation and event handling capabilities similar to @ckeditor/ckeditor5-utils, it is a larger library and includes many features that may not be necessary for all projects.
EventEmitter3 is a high-performance event emitter for Node.js and the browser. It provides a simple and efficient way to handle events, similar to the EmitterMixin in @ckeditor/ckeditor5-utils. However, EventEmitter3 focuses solely on event handling and does not include other utilities like DOM manipulation or data structures.

43.1.0 (September 5, 2024)
We are happy to announce the release of CKEditor 5 v43.1.0.
This release includes important bug fixes and enhancements for the editor:
Block merge fields: In contrast to regular, inline merge fields, the block merge fields are designed to represent complex, block-level structures, such as a dynamically generated table, a row of products, or a personalized call-to-action segment. Block merge fields are supposed to be replaced by arbitrary HTML data when the document template is post-processed or exported to a PDF or Word file.
Nested dropdown menus: this release introduces a new UI component: nested dropdown menus. They can be used by feature developers to easily provide an advanced user interface where UI elements are organized into a nested menu structure.
Customizable accessible label: You can now configure the label for the accessible editable area through the editor settings, ensuring it fits your system’s needs.
Improved table and cell border controls: It is now easier to manage both table and cell borders. The table user interface now clearly indicates the default border settings, allowing you to set “no borders” (None
) for tables and cells without any additional configuration.
⚠️ In some cases this update may lead to data changes in the tables’ HTML markup when the editor loads them. However, visually nothing will change, and the experience will be the same.
The full list of enhancements can be found below.
