CKEditor 5 editing engine

Dependency Status

The CKEditor 5 editing engine implements a flexible MVC-based architecture for creating rich text editing features.

Architecture overview

Custom data model. CKEditor 5 implements a tree-structured custom data model, designed to fit multiple requirements such as enabling real-time collaboration and complex editing features (like tables or nested blocks).
Virtual DOM. CKEditor 5's editing engine features a custom, editing-oriented virtual DOM implementation that aims to hide browser quirks from your sight. No more contentEditable nightmares!
Real-time collaborative editing. The editor implements Operational Transformation for the tree-structured model as well as many other mechanisms which were required to create a seamless collaborative UX. Additionally, we provide cloud infrastructure and plugins enabling real-time collaborative editing in your application! Check the collaboration demo.
Extensible. The entire editor architecture was designed for maximum flexibility. The code is event-based and highly decoupled, allowing you to plug in or replace selected pieces. Features do not directly depend on each other and communicate in standardized ways.
Schema-less core. The core makes minimal assumptions and can be controlled through the schema. This leaves all decisions to plugins and to you.
Modular architecture. Not only can the core modules be reused and recomposed but even the features were implemented in a highly granular way. Feel like running a headless CKEditor 5 with a couple of features in Node.js? Not a problem!
Framework for building rich-text editors. Every use case is different and every editor needs to fulfill different goals. Therefore, we give you the freedom to create your own editors with custom-tailored features and UI.
Heavily tested from day one. CKEditor 5 comes with 3x more tests than React itself. All packages have 100% code coverage.
8+ years of support. It is not yet another framework to be gone next year or a hyped proof-of-concept to fail in a real-life scenario. We have over 15 years of experience in creating rich text editors and invested over 4 years in designing and building your next future-proof rich text editor of choice.

Documentation

For a general introduction see the Overview of CKEditor 5 Framework guide and then the Editing engine architecture guide.
