将 Winston Logger 从 2.4.4 迁移到 3.x... 新的传输让我迷路了

Migrating Winston Logger from 2.4.4 to 3.x... The new transports have me lost

所以我正在尝试从 Winston 2.x 迁移到 3.x,但是它在设置传输方面发生了相当大的变化,我似乎无法让它工作我之前已经设置好了,更不用说改进它了。 我想要的控制台

[human-readable-date] [level(colourised)] : [text string], [formatted JSON]

在 2.4 中,我打印了 JSON,未格式化,这就足够了,但改进总是好的。

这是我的旧配置文件

const winston = require("winston");
require("winston-mongodb");
const config = require("./mongoDb").config;
const url = config.URL;

const tsFormat = () =>
  `${new Date().toLocaleDateString()} ${new Date().toLocaleTimeString()}`;

const logger = new winston.Logger({
  transports: [
    new winston.transports.Console({
      timestamp: tsFormat,
      colorize: true
    }),
    new winston.transports.MongoDB({
      timestamp: tsFormat,
      db: url,
      level: "debug",
      autoReconnect: true
    })
  ]
});
module.exports = logger;

--编辑--

这是我目前所在的位置

const winston = require("winston");
require("winston-mongodb");
const config = require("./");
const mongo = require("./mongo");

const logger = winston.createLogger({
  transports: [
    new winston.transports.Console({
      format: winston.format.combine(
        winston.format.colorize(),
        winston.format.timestamp({
          format: "YYYY-MM-DD HH:mm:ss"
        }),
        winston.format.align(),
        winston.format.printf(
          info => `${info.timestamp} ${info.level}: ${info.message}`
        )
      )
    }),

    new winston.transports.MongoDB({
      db: `${config.mongoURI}/${config.mongodb}`,
      level: "debug",
      tryReconnect: true,
      storeHost: true
    })
  ]
});
module.exports = logger;

但我无法让所需的 JSON 部分正常工作,或者无法将其发送到 mongodb

获得了与我喜欢的本地风格相似的结果 pino-pretty

能够打印出错误堆栈和其他元数据对象。

代码:

I added an additional custom field for a namespace because my app creates a child logger for each file rather then exposing the "root" logger using logger.child({ label: namespace })

winston.format.combine(
  winston.format.timestamp({ format: 'YYYY-MM-DD HH:mm:ss' }),
  winston.format.errors({ stack: true }),
  winston.format.colorize(),
  winston.format.printf(
    ({ timestamp, level, label, message, stack, ...rest }) => {
      const namespace = label ? `(${label})` : ''
      const errStack = stack ? `\n${stack}` : ''
      const meta =
        rest && Object.keys(rest).length
          ? `\n${JSON.stringify(rest, undefined, 2)}`
          : ''
      return `[${timestamp}] ${level}: ${namespace} ${message} ${meta} ${errStack}`
    }
  )
)

结果:
