typescript为winston日志级别添加颜色

Question

我正在尝试为winston的日志级别添加颜色。输出仍然没有颜色。

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

您不需要重新定义级别和颜色，只需将colorize: true传递给您的控制台传输即可：

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

Answer 2

// 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.');
