Collaboration in svelte-lexical

Collaboration is implemented using Yjs with y-websocket as the Connection provider.

Starting collaboration in the playground

There are two ways to start collaboration in the playground app.

Cross-tab communication (testing and development)

It works across tabs of a browser (no need to start a y-websocket server). Just start the playground app and turn on collaboration.

Svelte-lexical has a Split view that prvides a easier way to work with collaboration.

To start, add the following to the URL: /split/?isCollab=true

Or turn on, Split Split Screen and Collaboration from settings UI.

Start a collaboration server

1. Start the playground app (run pnpm dev from the /demos/playground folder)

2. Start the y-websocket server on localhost (run from /demos/playground folder)

   PORT=1234 pnpm y-websocket-server

3. Turn on Collaboration from settings in UI (or pass ?isCollab=true in the URL)

Properly boostrapping CollaborationPlugin

• set editor’s initialEditorState to null
• don’t use the HistoryPlugin with collaboration
• resolve path for Yjs in vite config

Yjs Synchronization issue with vite build in development mode [resolved]

Issue: Yjs was already imported. This breaks constructor checks and will lead to issues! (https://github.com/yjs/yjs/issues/438)
