co-log

基于log4js的nodejs日志库，支持requestId输出，支持koa.

Install

npm i co-log

Usage

import {Log} from 'co-log';

let log = new Log({path: '/opt/yourpath'});

Options

初始化参数

• 'path' - string类型，日志存放路径

const options= {
    path: '/opt/yourpath'
}

RequestId设置

log.setRequestId(string)

在function中设置requestId，所有console.log打印都带requestId

async function test() {
    log.setRequestId('ae21f206375744f0b6188f45b7f856d3')
    console.log({a:1})
    //[2022-11-24 23:18:47.160] [INFO] - ae21f206375744f0b6188f45b7f856d3 {a:1}
}

log.setRequestIdForKoa()

返回koa框架的中间件，所有api请求都自带requestId

const Koa = require('koa')
const app = new Koa()
//第一个引入log的中间件
app.use(log.setRequestIdForKoa());
