Text Editor Component Selection for JSON Formatters

'use client'; // Needed if using hooks or interactivity

import React, { useRef, useEffect, useState } from 'react';
// Assume 'some-editor-library' is your chosen library (CodeMirror, Monaco, etc.)
// You would import the actual editor core and JSON mode/language support
// import EditorComponent from 'some-editor-library';
// import 'some-editor-library/modes/json'; // Example for CodeMirror

interface JsonEditorProps {
  value: string;
  onChange: (newValue: string) => void;

  useEffect(() => {
    // Placeholder for editor initialization logic
    // This is where you'd instantiate CodeMirror.Editor, monaco.editor.create, etc.
    // You would configure it with JSON mode, themes, options
    // For example (CodeMirror concept):
    /*
    if (editorRef.current && !editorInstance.current) {
      editorInstance.current = CodeMirror(editorRef.current, {
        value: value,
        mode: 'application/json',

      });
      editorInstance.current.on('change', (instance) => {
        onChange(instance.getValue());
      });
    }
    */

    // For Monaco Editor, it might look different:
    /*
    if (editorRef.current && !editorInstance.current) {
       // Need to load the editor and its language first
       require.config({ paths: { 'vs': 'path/to/monaco-editor/min/vs' }});
       require(['vs/editor/editor.main'], () => {
         editorInstance.current = monaco.editor.create(editorRef.current, {
           value: value,
           language: 'json',
           automaticLayout: true, // Handle resizing
           // Other options like minimap, wordWrap etc.
         });
         editorInstance.current.onDidChangeModelContent(() => {
           onChange(editorInstance.current.getValue());
         });
       });
    }
    */

    // Cleanup function
    return () => {

        // editorInstance.current.toTextArea(); // CodeMirror
        // editorInstance.current.dispose(); // Monaco
      }
    };
  }, []); // Empty dependency array ensures this runs only once on mount

  useEffect(() => {
    // Update the editor content when the 'value' prop changes externally
    // Check if the current editor value is different to avoid infinite loops

import React, { useState } from 'react';
// Import your JsonEditor component
// import JsonEditor from './JsonEditor'; // Assuming the file is named JsonEditor.tsx
