Getting Started with React

Install lexical and @lexical/react:

npm install --save lexical @lexical/react

Below is an example of a basic plain text editor using lexical and @lexical/react (try it yourself).

import {$getRoot, $getSelection} from 'lexical';
import {useEffect} from 'react';

import LexicalComposer from '@lexical/react/LexicalComposer';
import LexicalPlainTextPlugin from '@lexical/react/LexicalPlainTextPlugin';
import LexicalContentEditable from '@lexical/react/LexicalContentEditable';
import {HistoryPlugin} from '@lexical/react/LexicalHistoryPlugin';
import LexicalOnChangePlugin from '@lexical/react/LexicalOnChangePlugin';
import {useLexicalComposerContext} from '@lexical/react/LexicalComposerContext';

const theme = {
// Theme styling goes here

// When the editor changes, you can get notified via the
// LexicalOnChangePlugin!
function onChange(editorState) { => {
// Read the contents of the EditorState here.
const root = $getRoot();
const selection = $getSelection();

console.log(root, selection);

// Lexical React plugins are React components, which makes them
// highly composable. Furthermore, you can lazy load plugins if
// desired, so you don't pay the cost for plugins until you
// actually use them.
function MyCustomAutoFocusPlugin() {
const [editor] = useLexicalComposerContext();

useEffect(() => {
// Focus the editor when the effect fires!
}, [editor]);

return null;

// Catch any errors that occur during Lexical updates and log them
// or throw them as needed. If you don't throw them, Lexical will
// try to recover gracefully without losing user data.
function onError(error) {

function Editor() {
const initialConfig = {

return (
<LexicalComposer initialConfig={initialConfig}>
contentEditable={<LexicalContentEditable />}
placeholder={<div>Enter some text...</div>}
<LexicalOnChangePlugin onChange={onChange} />
<HistoryPlugin />
<MyCustomAutoFocusPlugin />
