迁移到Winston 3并扩展Winston Logger

Question

我想将Winston Logger扩展到我的自定义记录仪。 在调用内部方法之前，我在哪里更新日志方法。

对于温斯顿2.4.x版 我这样做了。

var winston = require("winston");

var Logger = function(options){
  Logger.super_.apply(this, arguments);
}
util.inherits(Logger, winston.Logger);

Logger.prototype.log = function () {

  //some logic

  Logger.super_.prototype.log.apply(this, args);

};

Now, I am migrating to the Winston version 3.xx

I migrated the above code as

class Logger extends winston.createLogger {

  constructor(options) {
    super(options);
  }

  log() {

    //some logic

    super.log(args);
  };
}

The above code is able to create an instance of the logger and start logging the logs but it is not calling my log method instead it's only calling the inbuild Winston日志方法。
