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 🙏

用于处理不重要且需要执行的任务

原理

js脚本只能在一个线程里运行 我们看到的页面是能是一个屏幕里面的数据,这里面如果涉及到已有数据计算,那么就需要花费时间,如果这个时间很长,那么用户就会感觉到卡顿 我们可以把任务拆分,让任务分层运行,当需要的时候再进行计算,这样就解决了卡顿的问题 我们可以把任务分为3层

    1. 常任务
    1. 次任务 常任务是js主线程里面依次执行的 次级任务是常任务执行完之后执行,不影响页面执行,此时最好搭配后端校验,避免产生不必要的错误数据
实现

任务 - {常任务:【1,2,3,4】,次任务:【1,2,3,4】} 常任务依次执行,遇到添加的常任务 则次插入常任务列表 次任务依次执行,遇到添加的常任务 则优先执行常任务,在执行次任务
