CKEditor 5 editing engine

The package was moved to the main repository.
The CKEditor 5 editing engine implements a flexible MVC-based architecture for creating rich text editing features.
- 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
- 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.
