Monaco Editor Binding for Yjs - Demo

This binding maps a Y.Text to the Monaco editor (the editor that power VS Code).

Features

• Shared Cursors

Example

import * as Y from 'yjs'
import { WebsocketProvider } from 'y-websocket'
import { MonacoBinding } from 'y-monaco'
import * as monaco from 'monaco-editor'

const ydocument = new Y.Doc()
const provider = new WebsocketProvider(`${location.protocol === 'http:' ? 'ws:' : 'wss:'}//localhost:1234`, 'monaco', ydocument)
const type = ydocument.getText('monaco')

const editor = monaco.editor.create(document.getElementById('monaco-editor'), {
  value: '', // MonacoBinding overwrites this value with the content of type
  language: "javascript"
})

// Bind Yjs to the editor model
const monacoBinding = new MonacoBinding(type, editor.getModel(), new Set([editor]), provider.awareness)

Also look here for a working example.

API

import { MonacoBinding } from 'y-monaco'

const binding = new MonacoBinding(type, editor.getModel(), new Set([editor]), provider.awareness)

Class:MonacoBinding

Styling

You can use the following CSS classes to style remote cursor selections:

• yRemoteSelection
• yRemoteSelectionHead

See demo/index.html for example styles. Additionally, you can enable per-user styling (e.g.: different colors per user). The recommended approach for this is to listen to awareness.on("update", () => ...)); and inject custom styles for every available clientId. You can use the following classnames for this:

• yRemoteSelection-${clientId}
• yRemoteSelectionHead-${clientId

(where ${clientId} is the Yjs clientId of the specific user).
