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 🙏

Test-Network-Speed

✨ 一个轻量的前端测网速工具,利用图片探测、并行 Ajax 请求技术测量你的环境网络下载速度。

Features

  • 💪TypeScript

  • 🎶 ES2015

  • ✔ Promise

  • 🎨 Ajax

Install

npm i test-network-speed

Usage

import nst from "test-network-speed";
(async function () {
  const speedByImg = await nst.getSpeedByImg("./example.jpg", 734208);
  const speedByAjax = await nst.getSpeedByAjax("./example.jpg");
})();
  • getSpeedByImg:

    利用图片探测技术测量网速。

    优势:完全不必担心跨域的限制,使用简单。

    劣势:资源必须是图片且需要预先知道图片大小,灵活性较差;测得网速误差较大

  • getSpeedByAjax:

    利用 Ajax 并行发起多次网络请求,测得较为准确的网速。

    优势:不需要提前知道资源大小,类型随意,灵活性较好,测得网速值贴近真实值

    劣势:有跨域问题,且服务器配置 CORS 需要允许客户端自定义请求头 Cache-Control 字段
