⚠️ Migration Guide

Yjs is now decoupled from @blocknote/core. Instead of passing a collaboration option directly to the editor, you now wrap your editor options with the withCollaboration helper imported from @blocknote/core/yjs.

Before (< 0.52.0):

const editor = useCreateBlockNote({
  // ...other editor options
  collaboration: {
    provider,
    fragment: doc.getXmlFragment("document-store"),
    user: {
      name: "My Username",
      color: "#ff0000",
    },
  },
});

After (>= 0.52.0):

// Import the helper from the decoupled Yjs entrypoint:
import { withCollaboration } from "@blocknote/core/yjs";

const editor = useCreateBlockNote(
  withCollaboration({
    // ...other editor options
    collaboration: {
      provider,
      fragment: doc.getXmlFragment("document-store"),
      user: {
        name: "My Username",
        color: "#ff0000",
      },
    },
  }),
);

The collaboration object itself (provider, fragment, user, showCursorLabels, etc.) is unchanged — you only need to:

Import withCollaboration from @blocknote/core/yjs.
Wrap your editor options object with withCollaboration(...), keeping the collaboration property inside it.

The same applies when creating an editor with BlockNoteEditor.create(withCollaboration({ ... })).
