✨ Features

• Framework Agnostic: Works with React, Vue, Angular, Svelte, or vanilla JavaScript
• Type Safe: Full TypeScript support with comprehensive type definitions
• Modular Architecture: Plugin-based system for extending functionality
• Performance Optimized: Efficient DOM manipulation and memory management
• XSS Protection: Built-in content sanitization and security
• Accessibility: WCAG compliant with keyboard navigation support

🚀 Quick Start

Basic Usage

import { createEditor, EditorConfig } from '@editora/core';

import "@editora/themes/themes/default.css";
// Create editor configuration
const config: EditorConfig = {
  content: '<p>Hello World!</p>',
  placeholder: 'Start typing...',
  onChange: (html) => {
    console.log('Content changed:', html);
  }
};

// Create editor instance
const editor = createEditor(config);

// Mount to DOM element
const container = document.getElementById('editor');
editor.mount(container);

With Plugins

import { createEditor } from '@editora/core';
import { BoldPlugin, ItalicPlugin, HeadingPlugin } from '@editora/plugins';

import "@editora/themes/themes/default.css";

const editor = createEditor({
  plugins: [
    BoldPlugin(),
    ItalicPlugin(),
    HeadingPlugin()
  ],
  content: '<h1>Welcome</h1><p>Start writing...</p>'
});

editor.mount(document.getElementById('editor'));

Theme Usage

import "@editora/themes/themes/default.css";
import "@editora/themes/themes/dark.css";
import "@editora/themes/themes/acme.css";

• Core/React wrappers: apply a scope on a parent, for example <div data-theme="dark">...</div> or <div data-theme="acme">...</div>.
• Web component: set theme directly on the element, for example <editora-editor theme="dark"> or <editora-editor theme="acme">.

Web Component Config Additions

When using <editora-editor> or element.setConfig(...), these config groups are supported:

  enableARIA?: boolean;
  keyboardNavigation?: boolean;
  checker?: boolean;
};

performance?: {
  debounceInputMs?: number;
  viewportOnlyScan?: boolean;
};

🔌 Plugin System

Create custom plugins by extending the base Plugin class:

import { Plugin, Editor } from '@editora/core';

import "@editora/themes/themes/default.css";
class CustomPlugin extends Plugin {
  name = 'custom';
  
  install(editor: Editor) {
    // Plugin initialization
    console.log('Plugin installed');
  }
  
  execute(command: string, ...args: any[]) {
    // Handle commands
    if (command === 'doSomething') {
      // Custom logic
    }
  }
}
