如何使用 winston 和 simple() 獲得自定義 output？

Question

我正在嘗試使用 winston 獲得以下格式： 2020-01-01 [INFO]: test the level part colorized，而不是我得到

info: test

我怎樣才能得到我正在尋找的格式？

import winston from "winston";

const format = winston.format.combine(
  winston.format.align(),
  winston.format.colorize(),
  winston.format.errors({ stack: true }),
  winston.format.printf(
    ({ level, message }) => `[${level.toUpperCase()}]: ${message}`
  ),
  winston.format.simple(),
  winston.format.timestamp({ format: "YYYY-MM-DD HH:mm:ss" })
);

export const logger = winston.createLogger({
  level: process.env.NODE_ENV === "production" ? "info" : "debug",
  transports: [new winston.transports.Console({ format })],
});

使用以下修復

import winston from "winston";

const format = winston.format.combine(
  winston.format(info => ({ ...info, level: info.level.toUpperCase() }))(),
  winston.format.align(),
  winston.format.colorize(),
  winston.format.errors({ stack: true }),
  winston.format.prettyPrint(),
  winston.format.simple(),
  winston.format.splat(),
  winston.format.timestamp({ format: "YYYY-MM-DD HH:mm:ss" }),
  winston.format.printf(
    ({ timestamp, level, message }) => `${timestamp} [${level}]: ${message}`
  )
);

export const logger = winston.createLogger({
  level: process.env.NODE_ENV === "production" ? "info" : "debug",
  transports: [new winston.transports.Console({ format })],
});
