About Multi-User Collaboration

The frontend implementation logic for collaboration is located in the @suika/suika-multiplayer package. This package copies @suika/suika (pure client-side) and adds multi-user collaboration logic, such as multiple cursors, and calls some interfaces, like getting the drawing name and current user information.

Multi-user collaboration is implemented using yjs and the hocuspocus library (a further wrapper around yjs).

If you want to implement multi-user collaboration, you need to implement backend RESTful API services that this package uses, and provide WebSocket services based on hocuspocus.

Additionally, you need to implement a frontend workspace project to manage drawings, supporting login, registration, creating drawings, opening drawings, deleting drawings, and authorization.
