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 🙏

前端性能收集器

目前收集指标如下,后续酌情新增

  const INDICATORS = {
    // DNS查询耗时
    dns: '',
    
    // TCP连接耗时
    tcp: '',
    
    // TTFB(首字节时间)
    ttfb: '',
    
    // 白屏时间
    firstPaintTime: '',
    
    // DOMContentLoaded耗时
    domReady: '',
    
    // 页面加载完成耗时
    load: '',
  };

安装

  npm i performance-collector --save

使用

  import getPerformance from 'performance-collector';

  getPerformance((indicators) => {
    console.log(indicators);
  });

兼容性

实现中使用了addEventListener,所以不兼容IE8-(不会回调)。 性能参数主要通过performance.timing接口计算而来,不支持此接口的浏览器只会计算loaddomReady两个指标,其他指标为空。
