Below is an example of a basic plain text editor using lexical, @lexical/react, and yjs

import {$getRoot, $createParagraphNode, $createTextNode} from 'lexical';
import {LexicalComposer} from '@lexical/react/LexicalComposer';
import {ContentEditable} from '@lexical/react/LexicalContentEditable';
import {PlainTextPlugin} from '@lexical/react/LexicalPlainTextPlugin';
import {CollaborationPlugin} from "@lexical/react/LexicalCollaborationPlugin";
import * as Y from 'yjs';
import {WebsocketProvider} from 'y-websocket';

function initialEditorState(editor: LexicalEditor): void {
const root = $getRoot();
const paragraph = $createParagraphNode();
const text = $createTextNode('Welcome to collab!');

function Editor() {
const initialConfig = {
// NOTE: This is critical for collaboration plugin to set editor state to null. It
// would indicate that the editor should not try to set any default state
// (not even empty one), and let collaboration plugin do it instead
editorState: null,
namespace: 'Demo',
nodes: [],
onError: (error: Error) => {
throw error;
theme: {},

return (
<LexicalComposer initialConfig={initialConfig}>
contentEditable={<ContentEditable />}
placeholder={<div>Enter some text...</div>}
providerFactory={(id, yjsDocMap) => {
const doc = new Y.Doc();
yjsDocMap.set(id, doc);

const provider = new WebsocketProvider(

return provider;
// Optional initial editor state in case collaborative Y.Doc won't
// have any existing data on server. Then it'll user this value to populate editor.
// It accepts same type of values as LexicalComposer editorState
// prop (json string, state object, or a function)
