What is @ckeditor/ckeditor5-watchdog?

@ckeditor/ckeditor5-watchdog is a package designed to enhance the stability and reliability of CKEditor 5 by providing mechanisms to monitor and automatically recover from editor crashes. It ensures that the editor remains operational even in the face of unexpected errors.

What are @ckeditor/ckeditor5-watchdog's main functionalities?

Editor Watchdog

The Editor Watchdog monitors a single CKEditor 5 instance and automatically restarts it in case of a crash. This ensures that the editor remains available to the user.

const { EditorWatchdog } = require('@ckeditor/ckeditor5-watchdog');
const ClassicEditor = require('@ckeditor/ckeditor5-editor-classic/src/classiceditor');

const watchdog = new EditorWatchdog(ClassicEditor);

watchdog.create(document.querySelector('#editor'), {
    // Editor configuration.
}).catch(error => {
    console.error('Error initializing the editor:', error);
});

Context Watchdog

The Context Watchdog monitors a CKEditor 5 context, which can include multiple editor instances. It ensures that all editors within the context are restarted in case of a crash, maintaining the overall stability of the editing environment.

const { ContextWatchdog } = require('@ckeditor/ckeditor5-watchdog');
const Context = require('@ckeditor/ckeditor5-core/src/context');

const watchdog = new ContextWatchdog(Context);

watchdog.create({
    // Context configuration.
}).then(context => {
    // Create editors within the context.
}).catch(error => {
    console.error('Error initializing the context:', error);
});

react-error-boundary

react-error-boundary provides a reusable component for handling JavaScript errors in React components. It offers a way to catch errors in the component tree and display a fallback UI. While it is not specific to CKEditor, it serves a similar purpose of enhancing application stability by managing errors gracefully.

redux-saga

redux-saga is a library that aims to make application side effects (e.g., asynchronous actions) easier to manage, more efficient to execute, and better at handling failures. It provides mechanisms to handle errors and retries, which can be compared to the watchdog functionality in terms of ensuring application robustness.

raven-js

raven-js is the official browser JavaScript client for Sentry, a real-time crash reporting system. It captures and reports errors in web applications, providing insights into crashes and helping developers to fix issues. Similar to @ckeditor/ckeditor5-watchdog, it focuses on monitoring and recovering from errors.

Changelog

44.1.0 (December 16, 2024)

We are pleased to announce the latest CKEditor 5 release, focusing on performance enhancements and key bug fixes to improve your editing and collaboration experience.

Release Highlights

⚡ Performance enhancements: Part 3

This release introduces another set of performance related improvements, focused on faster editor initialization for huge documents. The initialization time was lowered by further 15% to 45%, depending on the tested sample.

The combined improvements introduced in recent releases amount to around 65%-80% lower loading time in total, which means the editor will load 3-5x faster. As the gain is not linear, bigger documents see even better improvement (more than 10x faster).

Moreover, all these improvements positively impact document save time (editor.getData()), which should help with autosave issues, among others.

We still actively work in this area, so you may expect even more editor load and save efficiency improvements in the upcoming releases.

🔨 Bug Fixes and improvements

• Comments enhancements:
  • Data export options: We introduced the showCommentHighlights option in editor.getData(), that changes the comment marker conversion, allowing for styling comments in the output. Perfect for showing what was commented in Export to PDF, for example.
  • Inline mode improvements: We addressed a problem where comment annotations in inline mode did not close properly when clicking elsewhere in the content.
  • Thread management: We resolved an issue where creating a new thread was not interrupted when the corresponding marker was removed from the content, ensuring better stability during collaborative editing.
• Revision History update:
  • Restore functionality: We disabled the ability to restore the current (edited, not saved) revision, as it represents current content, so there is nothing to restore. At the same time, using it led to some non-obvious behaviors.
• Image handling: We resolved an issue where images in the uploading state could be deleted when dragged and dropped within the editor. Keep dragging, even when it is not there 🙈.

🎄 Happy holidays!

As the holiday season approaches, we extend our warmest wishes to our community and users. Thank you for your continued support, and we look forward to bringing you further enhancements and exciting features in the coming year.
