Tentap Editor

TenTap Editor

A typed, customizable, and extendable rich text editor for React Native built on Tiptap and Prosemirror. TenTap provides a bridge architecture that enables seamless communication between React Native and a web-based editor, offering powerful editing capabilities with native mobile performance.

Core Functionality

TenTap Editor delivers comprehensive rich text editing capabilities through a WebView-based architecture that bridges React Native and Tiptap. It provides essential features including text formatting (bold, italic, underline, strikethrough), lists (bullet, ordered, task), headings, blockquotes, code blocks, images, links, colors, and highlights. The editor supports custom themes, dark mode, dynamic CSS injection, custom fonts, and full extensibility through custom bridge extensions.

When to Use

Use TenTap when building mobile applications requiring rich text editing, including chat interfaces, email composers, content management systems, note-taking apps, social media platforms, document editors, or any application where users need to format text beyond plain input. It offers both simple plug-and-play usage for standard features and advanced customization for specialized requirements.

Quick Start

Installation

React Native:

yarn add @10play/tentap-editor react-native-webview
cd ios && pod install

Expo:

npx expo install @10play/tentap-editor react-native-webview

Note: Expo Go supports only basic usage. For advanced features, use Expo Dev Client.

Basic Setup

The simplest implementation requires three components: useEditorBridge hook, RichText component, and Toolbar component.

import { KeyboardAvoidingView, StyleSheet } from 'react-native';
import { SafeAreaView } from 'react-native-safe-area-context';
import { RichText, Toolbar, useEditorBridge } from '@10play/tentap-editor';

export const BasicEditor = () => {
  const editor = useEditorBridge({
    autofocus: true,
    avoidIosKeyboard: true,
    initialContent: '<p>Start editing!</p>',
  });

  return (
    <SafeAreaView style={styles.fullScreen}>
      <RichText editor={editor} />
      <KeyboardAvoidingView
        behavior="padding"
        style={styles.keyboardAvoidingView}
      >
        <Toolbar editor={editor} />
      </KeyboardAvoidingView>
    </SafeAreaView>
  );
};

const styles = StyleSheet.create({
  fullScreen: { flex: 1 },
  keyboardAvoidingView: {
    position: 'absolute',
    width: '100%',
    bottom: 0,
  },
});

This creates a fully functional rich text editor with standard formatting capabilities. See references/Basic.tsx for the complete working example.

Core Concepts

Bridge Architecture

TenTap uses a bridge pattern to communicate between React Native and the Tiptap editor running in a WebView:

• EditorBridge: Main interface providing all editor commands accessible from React Native
• BridgeExtension: Typed classes that extend editor functionality by wrapping Tiptap extensions
• BridgeState: Real-time state object reflecting the editor's current status

This architecture enables powerful features while maintaining type safety and minimizing WebView-Native communication overhead.

Usage Patterns

Simple Usage: Pre-configured with TenTapStarterKit including all standard rich text features. Ideal for most use cases requiring standard formatting capabilities.

Advanced Usage: Custom bundling with Vite for full control over the web editor, custom Tiptap extensions, and specialized bridge implementations. Required when adding custom extensions beyond the pre-built bridges.

Essential APIs

useEditorBridge Hook

The primary hook for creating and configuring an EditorBridge instance.

Key Configuration Options:

• bridgeExtensions: Array of BridgeExtensions (default: TenTapStarterKit)
• initialContent: HTML string or JSON object for initial editor content
• autofocus: Auto-focus editor on mount (default: false)
• avoidIosKeyboard: Keep cursor visible above keyboard (default: false, works on both iOS and Android)
• dynamicHeight: WebView height matches content height (default: false)
• theme: Custom theme configuration for native components
• editable: Enable/disable editing (default: true)
• customSource: Custom HTML string for advanced setups
• onChange: Callback fired on content changes
• DEV / DEV_SERVER_URL: Development mode configuration for advanced setups

const editor = useEditorBridge({
  autofocus: true,
  avoidIosKeyboard: true,
  initialContent: '<p>Hello, world!</p>',
  bridgeExtensions: [...TenTapStartKit, CustomBridge],
  onChange: () => {
    // Handle content changes (debounce recommended)
  },
});

See references/useEditorBridge.md for complete API documentation.

State Management Hooks

useBridgeState: Subscribe to real-time editor state changes.

const editorState = useBridgeState(editor);

// Access state properties
editorState.isFocused;      // Editor focus state
editorState.isEmpty;        // Whether editor is empty
editorState.isBoldActive;   // Bold formatting state
editorState.canToggleBold;  // Whether bold can be toggled
editorState.headingLevel;   // Current heading level

BridgeState includes 30+ properties tracking formatting states, capabilities, and editor status. See references/BridgeState.md for complete property listing.

useEditorContent: Efficiently retrieve editor content with built-in debouncing.

const htmlContent = useEditorContent(editor, { type: 'html' });

// Alternative content types
const textContent = useEditorContent(editor, { type: 'text' });
const jsonContent = useEditorContent(editor, { type: 'json' });

// Custom debounce interval (default: 10ms)
const content = useEditorContent(editor, {
  type: 'html',
  debounceInterval: 100,
});

Configuring Extensions

Use configureExtension to customize Tiptap extension settings:

const editor = useEditorBridge({
  bridgeExtensions: [
    ...TenTapStartKit,
    PlaceholderBridge.configureExtension({
      placeholder: 'Type something amazing...',
    }),
    LinkBridge.configureExtension({
      openOnClick: false,
    }),
    HeadingBridge.configureExtension({
      levels: [1, 2, 3],
    }),
  ],
});

Extending Document Schema

Use extendExtension to modify the document schema:

CoreBridge.extendExtension({
  content: 'heading block+',
});

This configures the document to require a heading as the first node.

See references/BridgeExtensions.md and references/configureExtensions.md for complete extension reference and configuration examples.

Customization Guide

Theming

Apply custom themes to native components using the theme configuration:

const editor = useEditorBridge({
  theme: {
    toolbar: {
      toolbarBody: {
        backgroundColor: '#474747',
        borderTopColor: '#C6C6C6B3',
        borderBottomColor: '#C6C6C6B3',
      },
    },
    webview: {
      backgroundColor: '#1C1C1E',
    },
    webviewContainer: {},
  },
});

Dark Mode

Implement complete dark mode by combining native theme and web CSS:

import { darkEditorTheme, darkEditorCss } from '@10play/tentap-editor';

const editor = useEditorBridge({
  bridgeExtensions: [
    ...TenTapStartKit,
    CoreBridge.configureCSS(darkEditorCss),
  ],
  theme: darkEditorTheme,
});

See references/darkTheme.md and references/DarkEditor.tsx for complete dark mode implementation.

Custom CSS

Override or extend default CSS for any bridge extension:

const customCodeCSS = `
code {
  background-color: #ffdede;
  border-radius: 0.25em;
  color: #cd4242;
  padding: 0.25em;
}
`;

const editor = useEditorBridge({
  bridgeExtensions: [
    ...TenTapStartKit,
    CodeBridge.configureCSS(customCodeCSS),
  ],
});

Dynamic CSS Injection

Update CSS at runtime using the injectCSS method:

// Update bridge-specific CSS
editor.injectCSS(newCSS, CodeBridge.name);

// Add new stylesheet without overriding
editor.injectCSS(customCSS, 'custom-tag');

Custom Fonts

Integrate custom fonts by converting to base64 and configuring via CSS:

1. Convert font files using https://transfonter.org (check base64 option)
2. Export the stylesheet.css as a TypeScript string
3. Configure via CoreBridge CSS:

import { customFont } from './font';

const editor = useEditorBridge({
  bridgeExtensions: [
    ...TenTapStartKit,
    CoreBridge.configureCSS(customFont),
  ],
});

See references/customCss.md and references/CustomCss.tsx for complete CSS and font customization examples.

Advanced Setup

For custom Tiptap extensions or specialized editor behavior, use advanced setup with custom bundling.

Overview

Advanced setup provides:

• Full control over Tiptap extensions
• Custom bridge implementations
• Specialized editor configurations
• Development server integration

Process

1. Create editor-web directory: Separate folder for web editor code
2. Configure TypeScript: Set up web-specific tsconfig.json
3. Create editor files: index.html, AdvancedEditor.tsx, index.tsx
4. Set up Vite: Configure bundler with module aliases
5. Add build scripts: Package.json scripts for dev and production
6. Import custom bundle: Use generated HTML with customSource prop

Complete Example

// editor-web/AdvancedEditor.tsx
import { EditorContent } from '@tiptap/react';
import { useTenTap, TenTapStartKit } from '@10play/tentap-editor';
import { CounterBridge } from '../CounterBridge';

export const AdvancedEditor = () => {
  const editor = useTenTap({
    bridges: [...TenTapStartKit, CounterBridge],
    tiptapOptions: {
      extensions: [Document, Paragraph, Text],
    },
  });

  return <EditorContent editor={editor} />;
};

// In React Native app
import { editorHtml } from './editor-web/build/editorHtml';

const editor = useEditorBridge({
  customSource: editorHtml,
  // ... other config
});

Creating Custom Bridges

Implement custom bridge extensions for specialized functionality:

import { BridgeExtension } from '@10play/tentap-editor';
import { CharacterCount } from '@tiptap/extension-character-count';

export const CounterBridge = new BridgeExtension<
  typeof CharacterCount,
  { words: number; characters: number }
>({
  tiptapExtension: CharacterCount,
  extendEditorState: (editor) => ({
    words: editor.storage.characterCount.words(),
    characters: editor.storage.characterCount.characters(),
  }),
});

See references/advancedSetup.md and references/Advanced/ for complete advanced setup instructions and working examples.

Platform-Specific Considerations

iOS Keyboard Handling

When using React Navigation headers on iOS, configure KeyboardAvoidingView with proper offsets:

import { useSafeAreaInsets } from 'react-native-safe-area-context';
import { Platform } from 'react-native';

const HEADER_HEIGHT = 38;
const { top } = useSafeAreaInsets();
const keyboardVerticalOffset = HEADER_HEIGHT + top;

<KeyboardAvoidingView
  behavior="padding"
  keyboardVerticalOffset={Platform.OS === 'ios' ? keyboardVerticalOffset : undefined}
>
  <Toolbar editor={editor} />
</KeyboardAvoidingView>

// Add paddingBottom to RichText container on iOS
<View style={{ paddingBottom: Platform.OS === 'ios' ? HEADER_HEIGHT : 0 }}>
  <RichText editor={editor} />
</View>

See references/navHeader.md and references/NavigationHeader.tsx for complete iOS keyboard handling examples.

Avoid iOS Keyboard Option

The avoidIosKeyboard option helps keep the cursor visible when the editor is full-screen:

const editor = useEditorBridge({
  avoidIosKeyboard: true,  // Works on both iOS and Android
});

This automatically:

• Adds bottom padding equal to keyboard height
• Adjusts ProseMirror scroll threshold and margin
• Ensures cursor remains visible during typing
