What is @ckeditor/ckeditor5-utils?
@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.
What are @ckeditor/ckeditor5-utils's main functionalities?
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' }
Other packages similar to @ckeditor/ckeditor5-utils
lodash
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
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
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.
