我采用了将输出流交换为我的流的想法。

const LogLater                = require ('./loglater.js');
var logfile=new LogLater( 'log'+( new Date().toISOString().replace(/[^a-zA-Z0-9]/g,'-') )+'.txt' );


var PassThrough = require('stream').PassThrough;

var myout= new PassThrough();
var wasout=console._stdout;
myout.on('data',(data)=>{logfile.dateline("\r\n"+data);wasout.write(data);});
console._stdout=myout;

var myerr= new PassThrough();
var waserr=console._stderr;
myerr.on('data',(data)=>{logfile.dateline("\r\n"+data);waserr.write(data);});
console._stderr=myerr;

loglater.js:

const fs = require('fs');

function LogLater(filename, noduplicates, interval) {
    this.filename = filename || "loglater.txt";
    this.arr = [];
    this.timeout = false;
    this.interval = interval || 1000;
    this.noduplicates = noduplicates || true;
    this.onsavetimeout_bind = this.onsavetimeout.bind(this);
    this.lasttext = "";
    process.on('exit',()=>{ if(this.timeout)clearTimeout(this.timeout);this.timeout=false; this.save(); })
}

LogLater.prototype = {
    _log: function _log(text) {
        this.arr.push(text);
        if (!this.timeout) this.timeout = setTimeout(this.onsavetimeout_bind, this.interval);
    },
    text: function log(text, loglastline) {
        if (this.noduplicates) {
            if (this.lasttext === text) return;
            this.lastline = text;
        }
        this._log(text);
    },
    line: function log(text, loglastline) {
        if (this.noduplicates) {
            if (this.lasttext === text) return;
            this.lastline = text;
        }
        this._log(text + '\r\n');
    },
    dateline: function dateline(text) {
        if (this.noduplicates) {
            if (this.lasttext === text) return;
            this.lastline = text;
        }
        this._log(((new Date()).toISOString()) + '\t' + text + '\r\n');
    },
    onsavetimeout: function onsavetimeout() {
        this.timeout = false;
        this.save();
    },
    save: function save() { fs.appendFile(this.filename, this.arr.splice(0, this.arr.length).join(''), function(err) { if (err) console.log(err.stack) }); }
}

module.exports = LogLater;

我自己简单地从温斯顿的例子，并添加了log(…)方法(因为温斯顿命名为info(..):

Console.js:

"use strict"

// Include the logger module
const winston = require('winston');

const logger = winston.createLogger({
    level: 'info',
    format: winston.format.json(),
    transports: [
        //
        // - Write to all logs with level `info` and below to `combined.log`
        // - Write all logs error (and below) to `error.log`.
        //
        new winston.transports.File({ filename: 'error.log', level: 'error' }),
        new winston.transports.File({ filename: 'combined.log' })
    ]
});

//
// If we're not in production then log to the `console` with the format:
// `${info.level}: ${info.message} JSON.stringify({ ...rest }) `
//
if (process.env.NODE_ENV !== 'production') {
    logger.add(new winston.transports.Console({
        format: winston.format.simple()
    }));
}

// Add log command
logger.log=logger.info;

module.exports = logger;

然后在代码中使用:

const console = require('Console')

现在你可以简单地在你的文件中使用正常的日志功能，它会创建一个文件并将其记录到你的控制台(在调试/开发时)。因为if (process.env。NODE_ENV !== 'production'){(如果你想让它也在生产环境中)…

你也可以看看这个npm模块: https://www.npmjs.com/package/noogger

努格

简单直接……

如果你正在使用forever来保持节点应用程序运行，那么输入forever list将显示console.log正在写入的日志文件的路径

你可以使用nodejs的Console构造函数

const mylog = new console.Console(
  fs.createWriteStream("log/logger.log"),
  fs.createWriteStream("log/error.log")
);

然后你就可以像使用普通的控制台类一样使用它了，例如:

mylog.log("Ok!"); // Will be written into 'log/logger.log'
mylog.error("Bad!"); // Will be written into 'log/error.log'

对于未来的用户。@keshavDulal答案不适用于最新版本。而且我无法找到针对最新版本3.3.3中报告的问题的适当修复。

不管怎样，在研究了一下之后，我终于把它修好了。下面是温斯顿3.3.3版本的解决方案

安装winston和winston-daily-rotate-file

npm install winston 
npm install winston-daily-rotate-file

创建一个新文件utils/logger.js

const winston = require('winston');
const winstonRotator = require('winston-daily-rotate-file');

var logger = new winston.createLogger({
  transports: [
    new (winston.transports.DailyRotateFile)({
      name: 'access-file',
      level: 'info',
      filename: './logs/access.log',
      json: false,
      datePattern: 'yyyy-MM-DD',
      prepend: true,
      maxFiles: 10
    }),
    new (winston.transports.DailyRotateFile)({
      name: 'error-file',
      level: 'error',
      filename: './logs/error.log',
      json: false,
      datePattern: 'yyyy-MM-DD',
      prepend: true,
      maxFiles: 10
    })
  ]
});


module.exports = {
  logger
};

然后在任何你想要使用日志导入模块的文件

const logger = require('./utils/logger').logger;

像下面这样使用记录器:

logger.info('Info service started');
logger.error('Service crashed');
