javascript - winston : How to get logging with timestamp at the front

Question

如何配置Winston输出日志

2019-06-30 17:39:07:错误:奶酪已经腐烂

我尝试了这个，但它在末尾输出时间戳

const logger = winston.createLogger({
    format: winston.format.combine(
        winston.format.timestamp({format: 'YYYY-MM-DD HH:mm:ss'}),
        winston.format.simple()
    )
});

错误:奶酪已经腐烂! {“时间戳”:“2019-06-30 23:32:02”}

尝试下面的代码。我希望这能解决这个问题。您可以在myFormat自定义函数中按照自己需要的方式进行自定义

const myFormat = printf(({ level, message, label, timestamp }) => {
  return `${timestamp} : [${label}] : ${level}: ${message}`;
});

const logger = createLogger({
  format: combine(
    label({ label: 'right meow!' }),
    timestamp(),
    myFormat
  ),
  transports: [new transports.Console()]
});
