如何在 React Query 中实现数据同步和冲突解决？

import { useQuery } from 'react-query';

const MyComponent = () => {
  const { data, isLoading, isError } = useQuery('myData', fetchMyData, {
    refetchOnMount: true,
    refetchInterval: 5000, // 设置为 5 秒自动重新查询一次数据
  });

  if (isLoading) {
    return <div>Loading...</div>;
  }

  if (isError) {
    return <div>Error occurred!</div>;
  }

  return (
    <div>
      {/* 渲染数据 */}
    </div>
  );
};

import { useMutation, useQueryClient } from 'react-query';

const MyComponent = () => {
  const queryClient = useQueryClient();

  const mutation = useMutation(updateData, {
    // 请求完成后执行回调函数
    onSettled: (data, error, variables, context) => {
      // 处理请求完成后的数据同步和冲突解决
      if (error) {
        console.error(`Error occurred: ${error}`);
        return;
      }

      // 更新查询缓存中的数据
      queryClient.setQueryData('myData', data);
    },
  });

  // 处理数据修改
  const handleUpdateData = () => {
    const newData = // 获取要修改的数据
    mutation.mutate(newData);
  };

  return (
    <div>
      <button onClick={handleUpdateData}>Update Data</button>
    </div>
  );
};
