## 💻 Code Comparison

### Component Definition

**Angular:**
```typescript
@Component({
  selector: 'app-ckeditor-wrapper',
  standalone: true,
  imports: [CommonModule, CKEditorModule, ReactiveFormsModule, FormsModule],
  template: `...`,
  styles: [`...`],
  providers: [{
    provide: NG_VALUE_ACCESSOR,
    useExisting: forwardRef(() => CkeditorWrapperComponent),
    multi: true
  }]
})
export class CkeditorWrapperComponent implements ControlValueAccessor {
  @Input() label: string = '';
  @Input() placeholder: string = 'Enter text here...';
  // ... more inputs
}
```

**React:**
```typescript
interface CKEditorWrapperProps {
  value?: string;
  onChange?: (value: string) => void;
  label?: string;
  placeholder?: string;
  // ... more props
}

const CKEditorWrapper = forwardRef<CKEditorWrapperRef, CKEditorWrapperProps>(
  (props, ref) => {
    const [editorValue, setEditorValue] = useState(props.value);
    // ... component logic
  }
);
```

### SSR Detection

**Angular:**
```typescript
constructor(@Inject(PLATFORM_ID) private platformId: Object) {
  this.isBrowser = isPlatformBrowser(this.platformId);
  
  if (this.isBrowser) {
    import('@ckeditor/ckeditor5-build-classic').then(module => {
      this.Editor = module.default;
    });
  }
}
```

**React:**
```typescript
const [isBrowser, setIsBrowser] = useState(false);

useEffect(() => {
  setIsBrowser(typeof window !== 'undefined');
}, []);

useEffect(() => {
  if (isBrowser && !CKEditor) {
    Promise.all([
      import('@ckeditor/ckeditor5-react'),
      import('@ckeditor/ckeditor5-build-classic')
    ]).then(([CKEditorComponent, ClassicEditorModule]) => {
      CKEditor = CKEditorComponent.CKEditor;
      ClassicEditor = ClassicEditorModule.default;
    });
  }
}, [isBrowser]);
```

### Template/JSX

**Angular:**
```html
<div class="ckeditor-wrapper">
  <label *ngIf="label">
    {{ label }}
    <span *ngIf="required">*</span>
  </label>
  <ckeditor 
    *ngIf="isBrowser && Editor"
    [editor]="Editor" 
    [config]="editorConfig"
    [(ngModel)]="value"
    (ngModelChange)="onEditorChange()">
  </ckeditor>
  <textarea 
    *ngIf="!isBrowser || !Editor"
    [(ngModel)]="value">
  </textarea>
</div>
```

**React:**
```tsx
<div className="ckeditor-wrapper">
  {label && (
    <label>
      {label}
      {required && <span>*</span>}
    </label>
  )}
  {isBrowser && isEditorReady && CKEditor && ClassicEditor ? (
    <CKEditor
      editor={ClassicEditor}
      config={editorConfig}
      data={editorValue}
      onChange={handleEditorChange}
    />
  ) : (
    <textarea
      value={editorValue}
      onChange={handleTextareaChange}
    />
  )}
</div>
```

## 🔧 Usage Comparison

### Basic Usage

**Angular:**
```html
<app-ckeditor-wrapper
  formControlName="description"
  label="Description"
  [required]="true"
  [maxLength]="5000">
</app-ckeditor-wrapper>
```

**React:**
```tsx
<CKEditorWrapper
  value={description}
  onChange={setDescription}
  label="Description"
  required={true}
  maxLength={5000}
/>
```

### Form Setup

**Angular:**
```typescript
// Component
export class MyComponent {
  form = this.fb.group({
    description: ['', [Validators.required, Validators.maxLength(5000)]]
  });
  
  constructor(private fb: FormBuilder) {}
}

// Template
<form [formGroup]="form">
  <app-ckeditor-wrapper formControlName="description"></app-ckeditor-wrapper>
</form>
```

**React:**
```typescript
// Component
function MyComponent() {
  const [description, setDescription] = useState('');
  const [touched, setTouched] = useState(false);
  
  const isValid = description.length > 0 && description.length <= 5000;
  
  return (
    <form>
      <CKEditorWrapper
        value={description}
        onChange={setDescription}
        onBlur={() => setTouched(true)}
        showError={touched && !isValid}
      />
    </form>
  );
}
```

### With Form Libraries

**Angular (Reactive Forms):**
```typescript
this.form = this.fb.group({
  title: ['', Validators.required],
  description: ['', [Validators.required, Validators.maxLength(5000)]],
  date: ['', Validators.required]
});
```

**React (React Hook Form):**
```typescript
const { control, handleSubmit } = useForm();

<Controller
  name="description"
  control={control}
  rules={{ required: true, maxLength: 5000 }}
  render={({ field }) => (
    <CKEditorWrapper
      value={field.value}
      onChange={field.onChange}
    />
  )}
/>
```

## 🎨 Styling

Both use **identical CSS** with minor syntax differences:

**Angular (Component Styles):**
```typescript
styles: [`
  .ckeditor-wrapper { width: 100%; }
  ::ng-deep .ck-editor__editable { min-height: 150px; }
`]
```

**React (CSS File):**
```css
.ckeditor-wrapper { width: 100%; }
.ckeditor-custom .ck-editor__editable { min-height: 150px; }
```
