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 🙏

异步队列同步化,支持递归嵌套

基于nodejs模块封装,同样适用于前端的异步同步化。

#安装

web版见:lib/queue_do_webjs.js

#原理和使用

文章见:http://www.html-js.com/?p=1474

支持异步同步化 同步化后成队列后执行回调方法 也可以异步处理队列,同时处理完毕后调用回调方法 具体见代码中的注释

  • @param array list 需要处理的数据的数组,作为参数传入handle_func第一个参数。
  • @param function handle_func 处理方法,第一个参数为数组的一个元素,第二个参数传入的是下一个loop方法,第三个参数是其loop的context
  • @param function next_func 队列处理完毕后调用的方法。
  • @param boolen isAsyn 是否异步,如果是true,则不会同步化,可以利用next_func获取处理完毕的信号

#一个例子,递归遍历某个文件夹下所有的图片并压缩到1000宽度。

几个异步方法的同步化: 下面的例子是同步去请求豆瓣三个api,最后请求完后显示出来的例子。 只是示例,完整程序的一部分,不能运行。
