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 🙏

koa2-heartbeat

koa2 心跳检查中间件

需求背景

对于node服务,我们希望有一个与业务无关的路由,可以检查该服务是否”正常运转“,比如访问http://localhost:3000/heart/check,返回heart check passed !!!

使用

koa2-heartbeat中间件提供两个参数

  1. beatReg

表示要访问的该路由的匹配规则。默认是/^\/heart\/check/,也就是以为/heart/check开头

  1. beatMsg

表示命中上述路由之后,返回的消息内容,默认是heart check passed !!!


const Koa = require('koa')
const heartbeat = require('koa2-heartbeat')
const app = new Koa()
const PORT = 3000

// 1. 默认用法
app.use(heartBeat())
// 2. 添加自己的规则
app.use(heartBeat(/^\/health\/check/, 'health check passed !!!'))

app.listen(PORT, () => {
  console.log(`app start at: ${PORT}`)
})
