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 🙏

channel

来自clojure世界的csp,用js(web界的C++)实现

使用方法

npm i -S channel.js
const channel = require('channel');
const ch = new channel();

let tosay = [];
let todo = [];

function helloing(){
  ch.go(function*(){
    let i = 0;
    while(true){
      i++;
      yield ch.take(ch.timeout(1000));
      yield ch.put(tosay, "hello world"+i);
    }
  });
}

function walking(){
  ch.go(function*(){
    while(true){
      yield ch.take(ch.timeout(3000));
      yield ch.put(todo, "walking...");
    }
  });
}

function watchHelloing(){
  ch.go(function*(){
    while(true){
      let msg = yield ch.take(tosay);
      console.log(msg);
    }
  });
}

function watchWorking(){
  ch.go(function*(){
    while(true){
      let msg = yield ch.take(todo);
      console.log(msg);
    }
  });
}

watchWorking();
watchHelloing();
helloing();
walking();
/*
hello world1
hello world2
walking...
hello world3
hello world4
hello world5
walking...
  .
  .
  .
*/

响应式编程

现在我们对回调的描述,不再是基于时间线了,而是基于状态,描述事件的发生是分离的。

感谢大clojure,一直以来对我的帮助,无论是基本的语法还是这个相对core.async而言比较肤浅的小工具,得到了许多很热心的老手及大牛的帮助。
