Basic Text Editing
This code initializes a basic CKEditor 5 instance with classic build, allowing users to perform basic text editing tasks such as bold, italic, and underline.
import ClassicEditor from '@ckeditor/ckeditor5-build-classic';
ClassicEditor.create(document.querySelector('#editor'))
.then(editor => {
console.log('Editor was initialized', editor);
})
.catch(error => {
console.error(error);
});Custom Plugins
This code demonstrates how to initialize CKEditor 5 with custom plugins. In this example, only the Bold and Italic plugins are included, and the toolbar is customized to show only these options.
import ClassicEditor from '@ckeditor/ckeditor5-editor-classic/src/classiceditor';
import Essentials from '@ckeditor/ckeditor5-essentials/src/essentials';
import Bold from '@ckeditor/ckeditor5-basic-styles/src/bold';
import Italic from '@ckeditor/ckeditor5-basic-styles/src/italic';
ClassicEditor.create(document.querySelector('#editor'), {
plugins: [Essentials, Bold, Italic],
toolbar: ['bold', 'italic']
})
.then(editor => {
console.log('Editor was initialized with custom plugins', editor);
})
.catch(error => {
console.error(error);
});Real-time Collaboration
This code initializes CKEditor 5 with real-time collaboration features, allowing multiple users to edit the same document simultaneously and see each other's changes in real-time.

46.0.0 (July 9, 2025)
We are happy to announce the release of CKEditor 5 v46.0.0.
[!IMPORTANT]
This is a major release with significant amount of changes that may affect your CKEditor 5 integration. We strongly encourage you to read the entire update guide to understand all the changes. Pay special attention to:
- Unified exports and renames in the editor API: Many import/export names have changed
- Introduction of the default content styles: New default styling that may affect your content appearance These changes are designed to improve the long-term stability and maintainability of CKEditor 5, but they require careful attention during the upgrade process.
The new Line Height feature allows you to adjust the vertical spacing between lines of text, improving readability and visual harmony in your documents. This premium feature lets you set consistent line spacing across paragraphs and text blocks to enhance document accessibility and maintain visual hierarchy in your content.
Unneeded styles on block elements, such as tables and images, and General HTML Support nodes and attributes are finally eliminated when you hit the remove format button. The feature now cleans what it should, leaving the document structure untouched.
Working with styled lists becomes more intuitive as list markers (bullets and numbers) now automatically inherit text styling properties such as font size adjustments, text color changes, and font weight modifications (bold, italic).
This improvement makes it easier to create visually consistent and professional-looking lists without additional configuration. This improvement also supports Multi-level lists.
Important! This behavior is enabled by default, which means you may experience content change when you load the content to the editor 's new version (for the better in our opinion). But if this is not something you expect, you can opt out.
The Markdown feature dependencies have been modernized with a switch to the unified ecosystem, replacing the previous marked / turndown implementation. This change brings more consistent and symmetrical HTML ↔ Markdown conversion. By adopting remark and rehype from the same family of tools, we have created a more reliable and maintainable implementation that will better serve your document processing needs.
We have added the config.cloudServices.autoRefresh configuration property to disable the automatic token refresh mechanism. When it 's set to false, the token must be refreshed manually. This property opens up the ability to implement custom token handling if a certain use case requires this.
We have also introduced improvements to the addCommandThread command, which now supports creating comment threads on specified ranges. Additionally, it allows for creating a comment thread with an initial comment with the provided comment content.
Minor breaking change
The AddCommandThreadCommand#isEnabled property is no longer false when the current document selection is empty, as the command now allows for creating comment threads on custom ranges. If you previously used this property (for example, to provide a custom UI element), you should now use the observable AddCommentThreadCommand#hasContent property instead.
We have introduced dedicated methods for an easier way to get specific annotations related to a comment or a suggestion and vice versa.
After the big New Installation Method release (v42.0.0+), some developers upgrading from v41-x to v42-x were greeted by the does not provide an export named ... error. We addressed issues immediately as they were reported, but we knew it required a deeper are more comprehensive approach long-term.
With this release, we introduced a new, clear set of rules about internal imports, and also added re-exports if they were missing, changed the names of items to be more descriptive and avoid collisions, took care of internal methods that were already exported but not tagged, and cleaned up @deprecated code that was stale for some time.
If your build throws errors after the update, search and replace the old names with the new ones from the update guide. We have not changed the behavior of these APIs, just the names.
Last but not least, this release put us on the clean and straight path towards the deprecation of old installation methods. Please let us know if you have any questions on GitHub or support channels.
To improve the out-of-the-box experience and accessibility, we are introducing opinionated defaults for content styling. From this version, we ship a small defaults layer applied to .ck-content. These content styles are easily replaceable via CSS variable override. You may have already styled those things with more specific selectors.
While working on this initiative, we decided to standardize the CSS naming, too. All older variables that applied to the content styles now share the consistent --ck-content-* prefix. Read about the details in the update guide.
