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 🙏

recursion

如果有一组数据需要并发处理, 但是处理服务无法支持这么大的 QPS, 则可以将数据拆分,依次处理

import recursion from "@lijixuan/recursion";

const list = [];
for (let i = 0; i < 100000; i++) {
  list.push(i + 1);
}
console.time('recursion');
let index = 0;
// 将数据拆分,每一秒处理300条数据 
recursion(list, 300, function (value) {
  index += 1;
  console.log('Current content : %s', value);
  if (index === list.length) {
    console.log(index, list.length);
    console.timeEnd('recursion');
  }
});

参数定义

recursion(array, Qps, time, callback);

| 参数 | 是否必填 | 描述 | | ------ | ------ | ------ | | array | 是 | 一组数据 | | Qps | 否 | 单次处理的并发量 | | time | 否 | 每次数据处理间隔 | | callback | 否 | 回调函数 |

使用方法

const list = new Array(1000);
recursion(list, 10, 500, (value) => {
  console.log(value);
})

// 每次并发处理10个数据,每次处理间隔时间为500毫秒
const list = new Array(1000);
recursion(list, 10, (value) => {
  console.log(value);
})

每次并发处理10个数据,无间隔时间
const list = new Array(1000);
recursion(list, (value) => {
  console.log(value);
})
并发处理所有数据, 与使用 for 功能类似,该形式无任何意义,建议使用 for 循环处理
