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 🙏

automated-chrome-performance

基于puppeteer自动化采集指定url的性能数据(基于performance api)

  • 由于网络环境、浏览器启动等等原因,单次采集的数据会波动,所以采用运行多次取平均值的方式减小误差。默认一个页面会在puppeteer内打开100次,返回平均值。
  • 由于第一次启动浏览器话费时间较长,数据明显比后续打开页面采集的数据差异较大,故第一次的数据当脏数据过滤掉。

example

const getPerlog = require('automated-chrome-performance');
const test1 = 'https://www.baidu.com';
const test2 = 'https://www.taobao.com';
(async () => {
  var t1 = await getPerlog({url:test1, count: 10})
  var t2 = await getPerlog({url:test2, count: 10})
  for(var k in t1) {
    console.log(k, t1[k], t2[k])
  }
})()

options

  • url
    • 页面url地址
  • count
    • 执行次数,默认执行100次
  • headless
    • 是否开启headless,默认true
