• Error: Editor encountered an error
• Destroyed: Editor has been destroyed

Event System

The editor supports a rich event system:

interface EditorEvents {
  // Lifecycle events
  editorWillMount: () => void;
  editorDidMount: (editor) => void;
  
  // Content change events
  change: (value: string, event) => void;
  'update:value': (value: string) => void;
  
  // State events
  loading: (state: LoadingState) => void;
  error: (error: EditorError) => void;
  ready: () => void;
}
