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 🙏

Install

$ npm install @zhike/log-koa-middleware

Example

const logger = require('@zhike/log-koa-middleware')
const Koa = require('koa')

const app = new Koa()

//只打印requestBody
app.use(logger())

// 打印所有路径的headers中的content-type。只打印以/player2开头的路径的responseBody
app.use(logger({
    requestHeaders: ['content-type'],
    responseHeaders: ['content-type'],
    responseBodyWhiteList: ['/^\/player2/']
}))

Configuration Options

| 参数名 | 类型 | 说明 | | -------- | ----- | ------ | | reqId | String | 响应标识id(使用自定义的reqId需放在日志中间件前。如果为空且ctx.reqId为空则使用uuidv4自动生成reqId) | | requestHeaders | Array | 需要打印的request头部 (默认不打印) | | responseHeaders | Array | 需要打印的response头部 (默认不打印) | | responseBodyWhiteList | Array | 白名单,字符串数组,可为正则(对于正则匹配剔除部分路由,可在业务代码中的ctx.useResponseBodyOption=false跳过路由规则) | | responseBodyBlackList | Array | 黑名单,字符串数组,可为正则(对于正则匹配剔除部分路由,可在业务代码中使用ctx.useResponseBodyOption=false跳过路由规则) |

注意:

  1. 必会打印reqId,路径,方法,响应时间。
  2. 默认打印requestBody。
  3. 默认不打印responseBody。
  4. responseBodyWhiteList和不能和responseBodyBlackList同时传值
  5. responseBodyWhiteList和responseBodyBlackList暂未支持同一path不同method,后续会完善。
