Advice on implementing spell checker

[soapwong703]

I am developing a Spell Check Plugin and encountering some challenges. I am currently using registerLexicalTextEntity to monitor all TextNode updates and transform them into SpellCheckNode to enable specialized functionalities. However, the getMatch function in registerLexicalTextEntity appears to only support synchronous operations, while I need to query an asynchronous API to retrieve spelling check results as the user types.

At the moment, I have created a demo using a synchronous mock function. I would greatly appreciate any advice on how to implement this feature effectively.

// useSpellCheck.tsx
  useEffect(() => {
    if (!autoSpellCheck) return;
    return mergeRegister(
      ...registerLexicalTextEntity(
        editor,
        getSpellCheckMatch,
        SpellCheckNode,
        $createSpellCheckNode_
      )
    );
  }, [$createSpellCheckNode_, autoSpellCheck, editor, getSpellCheckMatch]);
