Contenido is a library with a set of tools to help you create your own rich text editor on top of draft-js without thinking about how to handle things.

// Custom Types
import { State } from '../../types';

const isLink = (editorState: State, customLinkKey?: string) => {
  const selectionState = editorState.getSelection();
  const contentState = editorState.getCurrentContent();
  const block = contentState.getBlockForKey(selectionState.getStartKey());
  const entityKey = block.getEntityAt(selectionState.getStartOffset());
  if (entityKey) {
    const entity = contentState.getEntity(entityKey);
    const entityType = entity.getType();
    return entityType === (customLinkKey ?? 'link');
  }
  return false;
};

export default isLink;
