温斯顿每日旋转文件 maxSize 不起作用

Question

代码如下。使用 winston daily rotate file 未创建新文件当达到 maxSize 即 2 mb 时，不会创建新文件。可能是什么问题呢？这是我的配置有问题的错误吗？我尝试添加删除扩展名或更改文件名，但它似乎不起作用

const customLevels = {
  levels: {
    debug: 3,
    info: 2,
    error: 1,
    critical: 0,
  },
  filename: {
    debug: path.join(
      __dirname,
      `../../logs/debug/%DATE%_debug`
    ),
    info: path.join(
      __dirname,
      `../../logs/info/%DATE%_info`
    ),
    error: path.join(
      __dirname,
      `../../logs/error/%DATE%_error`
    ),
    critical: path.join(
      __dirname,
      `../../logs/critical/%DATE%_critical`
    ),
  },
};

let logger = createLogger({
  levels: customLevels.levels,

  format: format.combine(
    format.timestamp({
      format: 'YYYY-MM-DD HH:mm:ss',
    }),
    format.simple()
  ),
  transports: [
    new transports.DailyRotateFile({
      filename: customLevels.filename.debug,
      maxsize: '2m',
      extension: '.log',
      level: 'debug',
    }),

    new transports.DailyRotateFile({
      filename: customLevels.filename.info,
      extension: '.log',
      maxsize: '2m',
      level: 'info',
    }),

    new transports.DailyRotateFile({
      filename: customLevels.filename.error,
      handleExceptions: true,
      maxsize: '2m',
      extension: '.log',
      level: 'error',
    }),

    new transports.DailyRotateFile({
      filename: customLevels.filename.critical,
      handleExceptions: true,
      extension: '.log',
      maxsize: '2m',
      level: 'critical',
    }),
  ],
  // exitOnError: false
});

您的代码具有键 maxsize，而实际上它应该是 maxSize。通常键和绑定名称是 JavaScript 中的驼峰式。您可以在 NPM 上看到这一点：

https://www.npmjs.com/package/winston-daily-rotate-file

其中给出了一个例子：

var transport = new (winston.transports.DailyRotateFile)({
    filename: 'application-%DATE%.log',
    datePattern: 'YYYY-MM-DD-HH',
    zippedArchive: true,
    maxSize: '20m',
    maxFiles: '14d'
  });

温斯顿每日旋转文件 maxSize 不起作用

Winston daily rotate file maxSize is not working
