Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

logger-util

日志打印与写入文件

Usage

  npm install logger-util --save
  • 使用示例
var Logger = require('logger-util')
/*
 * 配置参数
 * logging: 是否打印日志
 * level: 打印级别,分为六种'TRACE','DEBUG','INFO','WARN','ERROR','FATAL',设置打印该级别及以上,默认'TRACE'
 * saving: 是否生成日志文件
 * folderName: 生成日志的文件夹名字,默认为:'操作日志记录',当`saving`设置为`true`生效
 */

 // 使用自定义配置参数
var logger = new Logger({
  logging: true,
  level: 'TRACE',
  saving: true,
  folderName: '操作日志记录'
})

// 使用默认参数
// var logger = new Logger()
  • 打印
// color 仅改变当前行输出颜色(仅shell)
// 可选颜色:white black red green yellow blue purple azure
// logger.trace() logger.debug() logger.info() logger.warn() logger.error() logger.fatal()

logger.trace('key', 'value', 'red')
logger.trace('key', 'value')

// 不设置key时,默认将当前打印级别作为key
logger.trace('test')
  • 日志

    当参数配置为true时,才会生成日志文件否则只是格式化输出,结束时必须调用 end(), 同时end()该方法将返回一个 promise 可用.then()接收返回的对象,用作其他业务处理

logger
.sb('jokerchiu')
.action('add')
.resource('npm')
.end()
.then(result => logger.debug(result))

logger
.sb('jokerchiu')
.action('add')
.resource('npm')
.detail({name: 'logger-util'})
.ip('127.0.0.1')
.status('success')
.end()

logger.save({
  sb: 'joker',
  action: 'delete',
  resource: 'npm',
  detail: 'logger-util',
  ip: '0.0.0.0',
  status: '失败'}).end()
