将数据从MongoDB加载到React状态

import React, { useState, useEffect } from 'react';
import MongoDBDriver from 'mongodb'; // 假设这是MongoDB的驱动程序库

const MyComponent = () => {
  const [data, setData] = useState([]);

  useEffect(() => {
    // 在组件加载时执行数据库查询
    const fetchData = async () => {
      const client = new MongoDBDriver.MongoClient('mongodb://localhost:27017');
      await client.connect();

      const db = client.db('mydatabase');
      const collection = db.collection('mycollection');
      const query = { /* 查询条件 */ };
      const options = { /* 其他选项 */ };

      const result = await collection.find(query, options).toArray();
      setData(result);

      await client.close();
    };

    fetchData();
  }, []); // 空数组表示仅在组件加载时执行一次

  return (
    <div>
      {/* 在这里使用数据 */}
      {data.map(item => (
        <div key={item._id}>{item.name}</div>
      ))}
    </div>
  );
};

export default MyComponent;
