Quick Start

For framework-agnostic usage, start with the Vanilla JS quick start or the Vanilla JS example.

For React applications, install Lexical with the official React bindings:

npm install lexical @lexical/react

import { $getRoot, $getSelection } from 'lexical';
import { LexicalComposer } from '@lexical/react/LexicalComposer';
import { PlainTextPlugin } from '@lexical/react/LexicalPlainTextPlugin';
import { ContentEditable } from '@lexical/react/LexicalContentEditable';
import { HistoryPlugin } from '@lexical/react/LexicalHistoryPlugin';
import { LexicalErrorBoundary } from '@lexical/react/LexicalErrorBoundary';

const initialConfig = {
  namespace: 'MyEditor',
  onError: (error) => console.error(error),
};

function Editor() {
  return (
    <LexicalComposer initialConfig={initialConfig}>
      <PlainTextPlugin
        contentEditable={<ContentEditable />}
        ErrorBoundary={LexicalErrorBoundary}
      />
      <HistoryPlugin />
    </LexicalComposer>
  );
}

Try it yourself:
