打字稿為Winston日志記錄級別添加顏色

Question

我正在嘗試為Winston的日志記錄級別添加顏色。 輸出仍然沒有顏色。

import { addColors , Logger, LoggerInstance, transports, AbstractConfigSet } from "winston";

let level = "debug";

const levels = {
        debug: 0,
        info: 1,
        warn: 2,
        error: 3
    };

const colors = {
        debug: 'blue',
        info: 'green',
        warn: 'yellow',
        error: 'red'
    };


export const log: LoggerInstance = new Logger({
  transports: [ new transports.Console() ],
    level,
    levels
});

addColors(colors);

Answer 1

// for winston 3
var winston = require('winston');

const logger = module.exports = winston.createLogger({
  transports: [new winston.transports.Console()],
  format: winston.format.combine(
    winston.format.colorize({ all: true }),
    winston.format.simple()
  )
});;;

logger.log('info', 'This is an information message.');

您不需要重新定義級別和顏色，只需傳遞colorize: true對控制台傳輸為colorize: true ：

new Logger({
    transports: [
        new transports.Console({
            colorize: true
        })
    ]
});
