如何旋转使用pino-multi-stream生成的日志文件？

npm install pino-multi-stream

const pino = require('pino');
const multistream = require('pino-multi-stream');
const fs = require('fs');

function rotateLogFile(logFilePath, maxFileSize) {
  const stats = fs.statSync(logFilePath);
  const fileSizeInBytes = stats.size;

  if (fileSizeInBytes >= maxFileSize) {
    const rotatedLogFilePath = `${logFilePath}.${Date.now()}`;
    fs.renameSync(logFilePath, rotatedLogFilePath);
  }
}

const logFilePath = 'path/to/log/file.log';
const maxFileSize = 1024 * 1024; // 1MB

const streams = [
  { stream: process.stdout }, // 输出到控制台
  { stream: fs.createWriteStream(logFilePath, { flags: 'a' }) } // 输出到文件
];

const logger = pino({}, multistream(streams));

logger.info('This is an info log message');
logger.error('This is an error log message');
