  }
});

🎨 Component System

Button Component

createButton({
  label: 'Bold',
  icon: '<i class="fas fa-bold"></i>',  // Font Awesome icons supported
  command: 'bold',
  onclick: handler
})

States:

• inactive - Transparent (default)
• hover - Light gray background
• focus - Blue outline (keyboard nav)
• active - Primary blue with white text
• disabled - Reduced opacity, not-allowed cursor

Select Dropdown Component

createSelect({
  label: 'Heading',
  command: 'formatBlock',
  icon: '<i class="fas fa-heading"></i>',  // Icons now supported in dropdowns
  options: [
    { label: 'Paragraph', value: 'p' },
    { label: 'Heading 1', value: 'h1' },
    { label: 'Heading 2', value: 'h2' }
  ]
})

Color Picker Component

createColorPicker({
  label: 'Text Color',
  command: 'foreColor',
  value: '#000000'
})

Range Slider Component

createRangeSlider({
  label: 'Line Height',
  command: 'lineHeight',
  min: '0.8',
  max: '2.0'
})

� Advanced Paste Cleanup

Intelligent Word Detection

Automatically preserves Word formatting when content is copied from Microsoft Word:

// Content from Word automatically keeps ALL formatting
pasteCleanup: {
  formatOption: 'cleanFormat' // Word content bypasses all filtering
}

Word Detection markers:

• mso- CSS classes and styles
• w: and o: XML namespaces
• Conditional comments [if...][endif]
• Microsoft Office schemas
• Word-specific XML tags

Word content gets:

• ✅ Headings preserved as headings
• ✅ Alignment maintained (left, center, right, justify)
• ✅ Indentation and margins kept
• ✅ Font sizes and families preserved
• ✅ Line spacing and gaps maintained
• ✅ Lists and bullets preserved
• ✅ Tables and table formatting kept
• ✅ Colors and styling preserved

Configurable Content Filtering

For non-Word content, apply advanced filtering:

pasteCleanup: {
  formatOption: 'cleanFormat', // 'prompt', 'plainText', 'keepFormat', 'cleanFormat'
  deniedTags: ['script', 'style'], // Remove unwanted tags
  deniedAttributes: ['id', 'title'], // Remove problematic attributes
  allowedStyleProperties: ['color', 'margin', 'font-size'] // Keep only safe styles
}

Advanced Tag Patterns

Use attribute-based filtering:

deniedTags: [
  'a[!href]',        // Remove links without href
  'a[href, target]'  // Remove links with both href and target
]

�🔧 Architecture & Design Patterns

Configuration-Driven

Everything is controlled via config objects - no hardcoded content:

const editor = new RTE('container', {
  toolbar: [
    {
      group: 'formatting',
      items: [
        { type: 'button', label: 'Bold', command: 'bold', icon: 'B' }
      ]
    }
  ]
});

Command Handler

Centralized command processing with history management:

• Executes 50+ commands
• Tracks history for undo/redo
• Sanitizes all input
• Handles complex operations (links, tables, media)

State Manager

Real-time button state tracking:

• Monitors active formatting
• Updates ARIA attributes
• Toggles CSS classes
• Tracks disabled states

ES6 Modules

Prevents global scope pollution:

import { RTE } from './editor.js';
import { CommandHandler } from './commands/handler.js';

BEM CSS Methodology

Predictable, maintainable styling:

.rte__btn { }           /* Block */
.rte__btn--active { }   /* Modifier */
.rte__toolbar-group { } /* Element */

♿ Accessibility (WCAG AA Compliant)

✅ Semantic HTML

• <header> for toolbar
• <main> for content area

✅ ARIA Support

• aria-label on all controls
• aria-pressed for toggle state
• aria-multiline="true" on editor
• aria-modal on dialogs

✅ Keyboard Navigation

• Tab through all controls
• Ctrl+B/I/U/Z/Y shortcuts
• Focus-visible states
• Escape to close dialogs

✅ Color Contrast

• 4.5:1 minimum ratio
• Clear state distinctions

🚀 Getting Started

Installation

# Install from local package
npm install ../rte-package

# Install Font Awesome for icons (if using DEFAULT_TOOLBAR)
npm install @fortawesome/fontawesome-free

Include Font Awesome

<!-- Via CDN -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.4.0/css/all.min.css">

Basic Usage (Recommended)

import RTE from 'rte-package';
import { DEFAULT_TOOLBAR } from 'rte-package/src/config/defaults.js';

// Use defaults - instant full-featured editor!
const editor = new RTE('editor-container', {
  toolbar: DEFAULT_TOOLBAR
});

// Or filter to specific groups
const minimalEditor = new RTE('editor-container', {
  toolbar: DEFAULT_TOOLBAR.filter(g => ['formatting', 'paragraph'].includes(g.group))
});

// Get content
const html = editor.getContent();

// Set content
editor.setContent('<h1>Hello</h1>');

// Save
document.getElementById('save').onclick = () => {
  saveToDatabase(editor.getContent());
};

With Custom Toolbar (Advanced)

const editor = new RTE('editor', {
  toolbar: [
    {
      group: 'formatting',
      items: [
        { type: 'button', label: 'Bold', command: 'bold', icon: '<i class="fas fa-bold"></i>' }
      ]
    }
  ]
});
