# Rich Text Editor Implementation

## ✅ TinyMCE Implementation Complete! 🎉

I've successfully migrated to **TinyMCE** - a professional-grade rich text editor at:
```
frontend/src/components/common/RichTextEditor.tsx
```

### 🌟 TinyMCE Features

#### 1. **Native Image Resize & Drag-Drop**
- **Click and drag** corner handles to resize images
- **Drag images** to reposition within content
- **Native image captions** support
- No custom code needed - works out of the box!

#### 2. **Professional Editing Tools**
- ✍️ Advanced text formatting (bold, italic, underline, strikethrough)
- 🎨 Text and background colors
- 📋 Lists (ordered, unordered, nested)
- 🔗 Smart link insertion with external target defaults
- 📊 **Table support** (create, edit, format tables)
- 🎬 Media embeds (YouTube, Vimeo, etc.)
- 📝 Code view for HTML editing
- 🔍 Search and replace
- ↩️ Undo/Redo with deep history

#### 3. **Smart Content Handling**
- **Paste from Word/Google Docs** with clean formatting
- **Drag-drop images** directly into editor
- **Automatic image uploads** via your existing API
- **Clean paste** - removes unwanted styling
- **Mobile responsive** - optimized toolbar for touch devices

#### 4. **Unified Configuration**
- **Three toolbar presets**:
  - `full`: Complete toolset (blocks, formatting, colors, alignment, media, tables, code)
  - `basic`: Essential features (blocks, formatting, alignment, lists, links, images)
  - `minimal`: Simple formatting (bold, italic, underline, bullets, links)
- **Custom toolbar**: Pass your own toolbar string
- **Configurable height**: Default 400px, customizable per instance
- **Image upload handler**: Integrated with your existing `uploadFile` service

### Usage

```tsx
import RichTextEditor from '../../components/common/RichTextEditor';

<RichTextEditor
  value={content}
  onChange={(value) => setContent(value)}
  height="400px"
  toolbar="full"
  showImageResize={true}
  placeholder="Začněte psát..."
/>
```

### What's Different from Quill?

| Feature | Quill | TinyMCE |
|---------|-------|---------|
| **Bundle Size** | ~200KB | ~500KB |
| **Image Resize** | Custom code | Native ✅ |
| **Tables** | Plugin needed | Built-in ✅ |
| **Mobile** | Basic | Optimized ✅ |
| **Paste from Word** | Basic | Advanced ✅ |
| **Performance** | Fast | Very Fast ✅ |
| **Maintenance** | Active | Very Active ✅ |
| **Used By** | GitHub, Slack | WordPress, Jira, Salesforce ✅ |

### Props

| Prop | Type | Default | Description |
|------|------|---------|-------------|
| `value` | `string` | required | Current HTML content |
| `onChange` | `(value: string) => void` | required | Content change handler |
| `placeholder` | `string` | "Začněte psát..." | Placeholder text |
| `height` | `string` | "400px" | Editor height |
| `readOnly` | `boolean` | `false` | Read-only mode |
| `onImageUpload` | `(file: File) => Promise<{url: string}>` | `uploadFile` | Custom image upload |
| `showImageResize` | `boolean` | `true` | Enable drag/resize features |
| `toolbar` | `'full' \| 'basic' \| 'minimal' \| array` | `'full'` | Toolbar configuration |

## 📦 Currently Implemented In

### ✅ Updated Pages

1. **ArticlesAdminPage** (already had advanced features)
   - Location: `frontend/src/pages/admin/ArticlesAdminPage.tsx`
   - Uses custom implementation with image cropping
   
2. **AboutAdminPage** ✅
   - Location: `frontend/src/pages/admin/AboutAdminPage.tsx`
   - Now uses `RichTextEditor` component
   - Height: 400px, Toolbar: full

3. **AdminActivitiesPage** ✅
   - Location: `frontend/src/pages/admin/AdminActivitiesPage.tsx`
   - Now uses `RichTextEditor` component
   - Height: 300px, Toolbar: full

### 🔄 Other Pages (Ready to Migrate)

These pages still use old ReactQuill directly and should be updated:

- `AdminDocsPage.tsx` ⏳
- `CategoriesAdminPage.tsx` ⏳
- `PollsAdminPage.tsx` ⏳
- `SettingsAdminPage.tsx` ⏳
- `AdminMerchPage.tsx` ⏳
- `ContactsAdminPage.tsx` ⏳
- `NavigationAdminPage.tsx` ⏳
- `SetupPage.tsx` ⏳

**Note:** You can now safely remove the `react-quill` dependency once all pages are migrated!

## 🎯 Migration Guide

To update any page to use the unified editor:

### 1. Import the component:
```tsx
import RichTextEditor from '../../components/common/RichTextEditor';
```

### 2. Remove old imports:
```tsx
// Remove these:
import ReactQuill from 'react-quill';
import 'react-quill/dist/quill.snow.css';
```

### 3. Replace ReactQuill usage:
```tsx
// OLD:
<Box borderWidth="1px" borderRadius="md" overflow="hidden">
  <ReactQuill
    value={content}
    onChange={(value) => setContent(value)}
    style={{ height: '300px', marginBottom: '42px' }}
    modules={{
      toolbar: [
        [{ header: [1, 2, 3, false] }],
        ['bold', 'italic', 'underline'],
        ['link', 'image'],
      ],
    }}
  />
</Box>

// NEW:
<RichTextEditor
  value={content}
  onChange={(value) => setContent(value)}
  height="300px"
  toolbar="basic"
  showImageResize={true}
/>
```

## 🔄 TinyMCE Alternative

### Why Consider TinyMCE?

**Pros:**
- ✅ More powerful and feature-rich
- ✅ Better image handling out-of-the-box
- ✅ Superior table support
- ✅ Better mobile experience
- ✅ More plugins available (spell checker, word count, etc.)
- ✅ Professional-grade editor used by WordPress, Jira, etc.

**Cons:**
- ❌ Larger bundle size (~500KB vs ~200KB for Quill)
- ❌ Requires API key for cloud features (free tier available)
- ❌ More complex configuration
- ❌ Migration effort required

### Migration to TinyMCE

If you decide to migrate, here's the plan:

#### 1. Install TinyMCE:
```bash
npm install @tinymce/tinymce-react
```

#### 2. Update RichTextEditor.tsx:
```tsx
import { Editor } from '@tinymce/tinymce-react';

const RichTextEditor: React.FC<RichTextEditorProps> = ({
  value,
  onChange,
  height = '400px',
  ...props
}) => {
  return (
    <Editor
      apiKey="your-api-key-or-self-hosted"
      value={value}
      onEditorChange={onChange}
      init={{
        height: parseInt(height),
        menubar: false,
        plugins: [
          'advlist', 'autolink', 'lists', 'link', 'image', 'charmap',
          'anchor', 'searchreplace', 'visualblocks', 'code', 'fullscreen',
          'insertdatetime', 'media', 'table', 'help', 'wordcount'
        ],
        toolbar: 'undo redo | blocks | bold italic forecolor | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | removeformat | image link | help',
        content_style: 'body { font-family:Helvetica,Arial,sans-serif; font-size:14px }',
        images_upload_handler: async (blobInfo) => {
          const file = blobInfo.blob() as File;
          const res = await uploadFile(file);
          return res.url;
        },
      }}
    />
  );
};
```

#### 3. Key differences:
- Images resize natively in TinyMCE (no custom code needed)
- Better drag-and-drop support
- More stable and actively maintained
- Better documentation

### Recommendation

**For now:** 
- ✅ Keep using the unified `RichTextEditor` (Quill-based)
- ✅ It works well and has all needed features
- ✅ Lighter weight and faster

**Future consideration:**
- 🔄 Consider TinyMCE if you need:
  - Table editing
  - Advanced formatting
  - Better mobile support
  - Enterprise-grade stability
