定义组件

'use client'

import React, { useEffect, useRef } from 'react';

import * as monaco from 'monaco-editor';

const CodeEditor = ({ code, language, onChange, theme }) => {
    const editorRef = useRef(null);

    useEffect(() => {
        const editor = monaco.editor.create(editorRef.current, {
            value: code,
            language: language,
            theme: theme,
            lineNumbers: 'on',
            lineDecorationsWidth: 10,
            lineNumbersMinChars: 3,
            fontSize: 16,
            fontFamily: 'Consolas, "Courier New", monospace',
            automaticLayout: true,
            minimap: {
                enabled: false,
            },
            scrollBeyondLastLine: false,
            scrollbar: {
                vertical: 'hidden',
                horizontal: 'hidden',
            },
            wordWrap: 'on',
        });

        editor.onDidChangeModelContent(() => {
            onChange(editor.getValue());
        });
        // 组件卸载时销毁编辑器
        return () => {
         editor.dispose();
        };
    }, [theme,language]);

    return <div ref={editorRef} style={{ height: '80%', width: '1000px'}} />;
};

export default CodeEditor;

组件使用：

import {Typography, Flex, Row, Col, Space, Input, message, Button, Dropdown, Select} from 'antd';


export default function Page() {
    const [code, setCode] = useState<string>('');
    const [language, setLanguage] = useState<string>('python');
    const [theme, setTheme] = useState<string>('vs-light');

    const handleCodeChange = (value: string) => {
        setCode(value);
    };

    const handleChangeLanguage = (value: string) => {
        setLanguage(value);
        console.log(`selected ${value}`);
    };

    const handleChangeTheme = (value: string) => {
        setTheme(value)
        console.log(`selected ${value}`);
    };

	//......
