Performance Accessible Extensible Text Editor Framework – Lexical

Lexical is an extensible JavaScript web text-editor framework with an emphasis on reliability, accessibility, and performance.

Lexical aims to provide a best-in-class developer experience, so you can easily prototype and build features with confidence. Combined with a highly extensible architecture, Lexical allows developers to create unique text editing experiences that scale in size and functionality.

Basic usage:

1. Implement the Lexical with React.

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 OnChangePlugin from "@lexical/react/LexicalOnChangePlugin";
import TreeViewPlugin from "./plugins/TreeViewPlugin";
import EmoticonPlugin from "./plugins/EmoticonPlugin";
import MyCustomAutoFocusPlugin from "./plugins/MyCustomAutoFocusPlugin";
import editorConfig from "./editorConfig";
import onChange from "./onChange";
export default function Editor() {
  return (
    <LexicalComposer initialConfig={editorConfig}>
      <div className="editor-container">
        <PlainTextPlugin
          contentEditable={<ContentEditable className="editor-input" />}
          placeholder={<Placeholder />}
        />
        <OnChangePlugin onChange={onChange} />
        <HistoryPlugin />
        <TreeViewPlugin />
        <EmoticonPlugin />
        <MyCustomAutoFocusPlugin />
      </div>
    </LexicalComposer>
  );
}
function Placeholder() {
  return <div className="editor-placeholder">Enter some plain text...</div>;
}

2. Create a rich text editor.

import ExampleTheme from "./themes/ExampleTheme";
import LexicalComposer from "@lexical/react/LexicalComposer";
import RichTextPlugin from "@lexical/react/LexicalRichTextPlugin";
import ContentEditable from "@lexical/react/LexicalContentEditable";
import { HistoryPlugin } from "@lexical/react/LexicalHistoryPlugin";
import AutoFocusPlugin from "@lexical/react/LexicalAutoFocusPlugin";
import TreeViewPlugin from "./plugins/TreeViewPlugin";
import ToolbarPlugin from "./plugins/ToolbarPlugin";
import { HeadingNode, QuoteNode } from "@lexical/rich-text";
import { TableCellNode, TableNode, TableRowNode } from "@lexical/table";
import { ListItemNode, ListNode } from "@lexical/list";
import { CodeHighlightNode, CodeNode } from "@lexical/code";
import { AutoLinkNode, LinkNode } from "@lexical/link";
import LinkPlugin from "@lexical/react/LexicalLinkPlugin";
import ListPlugin from "@lexical/react/LexicalListPlugin";
import LexicalMarkdownShortcutPlugin from "@lexical/react/LexicalMarkdownShortcutPlugin";
import ListMaxIndentLevelPlugin from "./plugins/ListMaxIndentLevelPlugin";
import CodeHighlightPlugin from "./plugins/CodeHighlightPlugin";
import AutoLinkPlugin from "./plugins/AutoLinkPlugin";
function Placeholder() {
  return <div className="editor-placeholder">Enter some rich text...</div>;
}
const editorConfig = {
  // The editor theme
  theme: ExampleTheme,
  // Handling of errors during update
  onError(error) {
    throw error;
  },
  // Any custom nodes go here
  nodes: [
    HeadingNode,
    ListNode,
    ListItemNode,
    QuoteNode,
    CodeNode,
    CodeHighlightNode,
    TableNode,
    TableCellNode,
    TableRowNode,
    AutoLinkNode,
    LinkNode
  ]
};
export default function Editor() {
  return (
    <LexicalComposer initialConfig={editorConfig}>
      <div className="editor-container">
        <ToolbarPlugin />
        <div className="editor-inner">
          <RichTextPlugin
            contentEditable={<ContentEditable className="editor-input" />}
            placeholder={<Placeholder />}
          />
          <HistoryPlugin />
          <TreeViewPlugin />
          <AutoFocusPlugin />
          <CodeHighlightPlugin />
          <ListPlugin />
          <LinkPlugin />
          <AutoLinkPlugin />
          <ListMaxIndentLevelPlugin maxDepth={7} />
          <LexicalMarkdownShortcutPlugin />
        </div>
      </div>
    </LexicalComposer>
  );
}
