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 🙏

Log output middleware for koa

Readme

koa-sam-log koa2的日志输出中间件

基于log4js 3.0.6版本

安装

npm install koa-sam-log --save

基本使用

const myLog = require('koa-sam-log');

// myLog函数传入一个appender和一些其他配置
app.use(myLog({ 
    type: 'dateFile',   //按日期创建文件,文件名为 filename + pattern
    filename: 'logs/',
    pattern: 'yyyy-MM-dd.log',
    alwaysIncludePattern: true
},{
    env: app.env,      //如果是development则可以同时在控制台中打印
    level: 'info'      //logger level
}));

app.use()之后,即可使用ctx.log.info(), ctx.log.error()等log4js的方法
